Help me with a bash alias [SOLVED]

I want to make a bash alias to `alias tailc=tail -n40 $1 | column -t` so I put that in my ~/.bash_profile but it does not stop after 40 lines. It goes for the whole file. What am I doing wrong?

+1 - Make a function.  And `column -t` rocks.  I have been looking for a way to tail my server logs with the output being nicely formatted.  Thanks for this post.
tailc() { tail -n 40 "$1" | column -t; }

  • [solved]Need help with a bash script for MOC conky artwork.

    I need some help with a bash script for displaying artwork from MOC.
    Music folders have a file called 'front.jpg' in them, so I need to pull the current directory from MOCP and then display the 'front.jpg' file in conky.
    mocp -Q %file
    gives me the current file playing, but I need the directory (perhaps some way to use only everything after the last  '/'?)
    A point in the right direction would be appreciated.
    thanks, d

    You should also quote the variables and output in double quotes to make the code robust, e.g.
    filename="$(mocp -Q %file)"
    dirname="${filename%/*}"
    cp "$dirname"/front.jpg ~/backup/art.jpg
    Without the quotes, whitespace will break the code. Even if you don't expect whitespace in any of the paths, it's still good coding practice to include the quotes imo.
    thanks for the tip.
    here it is, anyhow:
    #!/bin/bash
    filename=$(mocp -Q %file)
    dirname=${filename%/*}
    cp ${dirname}/front.jpg ~/backup/art.jpg
    then in conky:
    $alignr${execi 30 ~/bin/artc}${image ~/backup/art.jpg -s 100x100 -p -3,60}
    thanks for the help.

  • [SOLVED] Trying to make command into bash alias

    Here is a command I would like to make into an easy to use bash alias:
    #Copy results of a find to somewhere
    find -iname "*something*" -exec cp '{}' /path/to/copy/results/to \;
    I realize there are usually several ways to do something in the shell, so if a better way of course I'm all for any tips but if I wanted to make this an alias so that I just had to do:
    alias pattern pathtocopyto
    How would I? I have tried:
    alias findcp="find -iname "$1" -exec cp '{}' $2/ \;"
    But this does not work, says it cannot find the search term when I ran it in a test dir full of properly named files and dirs.
    TIA for any help

    Yeah, I already found that post but the solution is not there. I'm not trying to use echo to set hostname manually, I'm trying to see why my hostnamectl command (and other *ctl comands) doesn't work, and there's no solution on that thread, just a workaround.
    I have systemd 195 and polkit 0.107 installed.
    EDIT: I replaced sysvinit with systemd-sysvcompat; then enabled syslog-ng, NetworkManager, and cronie services using systemctl enable; then I uninstalled initscripts. I'm not sure where during that process the commands started working, but they work now. But, that doesn't help people trying to migrate without having to replace sysvinit or remove initscripts first.
    This is a problem because the wiki explicitly says to migrate rc.d settings to the new files used by systemd. However, since the *ctl commands don't work at this point, it's impossible for the user to know how to make the config files manually without intimate knowledge of their formats without using *ctl commands.
    For example, how is one supposed to complete step one on the following wiki section? https://wiki.archlinux.org/index.php/Sy … stallation
    As you can see in those instructions, there is no information on how to create the new config files other than using *ctl commands, which don't even work at that stage. Some of the examples show a sample file, but the problematice ones are the ones that don't show a sample file.
    For example, how do you make /etc/adjtime without timedatectl?
    The wiki says that timedatectl [...] "will generate /etc/adjtime automatically; no further configuration is required", but then the Failed message in my original post is displayed.
    I think I will change the wiki to offer a better walk through when I get the chance to migrate to systemd on my desktop which has many daemons and modules.

  • HELP me with my K7N2 delta ilsr

    Can anyone help me with this problem. I have just upgraded to MSI's K7N2 delta ilsr motherboard. Its all working quite well apart from the fact that the pc wont start up from cold....at all.
    When I start the pc from an off state, it runs up the fans and drives, but does not post.
    The diagnostic led pannel on the back of the pc shows that the cpu is faulty or not installed correctly.
    If I then press the reset button, the pc posts, and boots up just fine.
    It does this EVERY time I start up.
    I have tried re installing the cpu, which is an XP 2800+ 333 barton, but to no avail.
    I have asked a few questions on other forums, but I cant solve it.
    These are the suggestions so far.
    1. the psu (I have a Tsunami 400 atx psu) could not be giving out enough power on initial startup, but once the pc is running, it has enough to boot the pc from a reset.
    2. The mobo or the bios could be at fault. I have not flashed the bios, or upgraded it in any way from original, so is there an issue with the original bios on these boards, and 2800 barton chips??? Could it be a mobo fault? The pc runs fine once the machine is booted.? how do I test it?
    3. The cpu could be faulty? but would this not stop it running fuull stop?
    4. my ram. I have a single stick of OCZ 512mb pc3200 ddr, which I was told would make the pc fly. Not shure on that statement, but is this ram compatible?? could this be the problem?
    Im fairly new to the upgrade side of things, and I need some help with this one.
    Also, Id be really greatfull if some one could talk me through flashing my bios to the latest version, as the thought of doing this narks me a bit...I dont want to mess it up and get a dead pc...

  • Help me with  this assignment

    can anyone out there help me with this assignment ????? i`ll attach the file to this topic
    In this assignment, you are to write a Java applet, using arrays, to simulate the functions of a drinks-vending machine.
    The assignment requirements described below are broken down into 2 stages of development, described in this document
    as 'Basic Requirements' and 'Additional Features'. You are advised to do your programming progressively in these
    stages. An Activity Plan has also been specified for you to follow. Refer to the 'Grading Criteria' on page 5 to have
    an idea of how the different components are graded.
    1.     1. BACKGROUND
    A company intends to build computerised drinks-vending machines to enlarge its business portfolio. You have been tasked to develop a
    Java applet that simulates the operation of such a machine to determine if it will meet their needs.
    2.     1. BASIC REQUIREMENTS
    The machine should have a wide range of drinks available. A customer can choose a drink according to the following criteria:
    a)     a) Category of Drinks
    �     � Beverages
    �     � Soft Drinks
    (For beverages, there is choice of whether sugar and/or creamer is required, for which there is an additional charge.)
    b)     b) Type of Beverages
    �     � Hot
    �     � Cold
    Once a customer has specified the drink he wants, the amount payable is displayed. The unit prices to be displayed are as follows:
    Drinks     Price per Cup/Packet ($)
    Beverage:     Coffee     1.00
         Tea     1.20
         Milo     1.40
         Horlicks     1.35
         Chrysanthemum     1.00
         Ginger     0.80
    Soft Drinks:     Apple     1.40
         Orange     1.40
         Pineapple     1.50
         Carrot     2.00
         Longan     1.20
         Bandung     1.00
    (For beverages, a request for sugar or creamer attracts an additional charge of $0.10 each. Creamer is not applicable for
    chrysanthemum and ginger.)
    The customer may then confirm his order by entering the amount payable (this symbolises his payment for the drink). Whenever the
    payment input is not correct, an appropriate error message is displayed, whereupon the customer has to re-enter the amount again.
    When the correct amount is paid, the required drink is dispensed.
    For any drink that is out of stock, a message is shown, stating that it is not available. Each time a drink is dispensed, the stock for that
    drink is updated (For beverages, the stock is stored in units of servings for each cup.) To simplify the testing, you may start the simulation
    by setting the stock for each drink to 10 packets or cup-servings.
    3.     2. ADDITIONAL FEATURES
    In addition, the simulator can have the following features:
    a)     a) Smart Graphical User-Interface (GUI)
    You may build upon the basic requirements by recommending alternative drinks of the same category, whenever a requested
    drink is not available (as signified from the stock). In this case, only drinks which are available (i.e., in sufficient stock) are
    displayed for the customer to choose. And if only soft drinks are available, the selections for creamer and sugar should be disabled.
    b)     b) Multiple Orders
    A customer could order more than one drink. The system could allow him to specify as many drinks as he wants, prompting him
    for an appropriate payment, and then dispensing the drinks accordingly, subject to availability. This may also entail the extension
    of the graphical user-interface.
    c)     c) Sales Analysis
    Periodically, the total revenue accumulated since the last collection is printed in descending order of sales for each drink sold,
    together with a grand total. The cash is then cleared from the machine. This feature requires password-protection.
    d)     d) Replenishment of Stock
    Periodically, the stock is checked to determine how much of each drink needs to be replenished. For this purpose, a list of the
    drinks with the corresponding quantity on hand is printed in ascending order of stock level. Drinks with insufficient stock are
    topped up to a level of 10 servings or packets. This feature also requires password-protection.
    e)     e) Any other relevant features
    You are limited only by your creativity. You can add any other relevant features for this project. Please consult your tutor before
    you proceed.
    To qualify for the full marks for this section, you need to implement 2 features, at least one of which must be either (a) or (b) above.
    4.     3. ACTIVITY PLAN
    Suggestions for Getting Started
    There are many ways that you could complete this assignment. The most important part is to think about the entire project first so that
    it is easy to integrate the various pieces. You should also consider what type of graphics you want to incorporate.
    a)     a) Analysis
    1. Understand the program specification and the requirements before attempting the project.
    b)     b) Program Design
    2.     Work out the GUI components (e.g., TextFields, CheckBoxes, ChoiceBoxes, Buttons, etc.) needed to get the user input.
    3.     3. Work out the main logic of the program using modular programming techniques; i.e. use methods appropriately. E.g., tasks that perform
    4.     4. a well-defined function or those that are repeated should be coded as methods. For example, you can write the methods, displayBill(),
    5.     5. makePayment(), computeTotal(), dispenseDrink(), etc. You need to think carefully about the return type and the parameters of each
    6.     6. method.
    7.     7. You are required to use arrays appropriately for this assignment. Marks will be deducted for inefficient use or non-usage of arrays.
    c) Implementation & Testing
    8.     8. Write the method definition of each method ONE at a time.
    9.     9. Test your program logic to make sure that it works. In the interim, you can use �g.drawString(�);� or �System.out.println(�);� to print
    10.     10. out intermediate results so that you can see whether your program is working correctly. You may not want to bother about error-checking
    11.     11. at this point. You should test each method as soon as it is written, as it is much easier to debug your program in this way.
    5.     4. DELIVERABLES
    By Monday, 25th February before 5:00 p.m., hand in the following to the School of ICT Administrative Office at Block 31, level 8:
    �     � A copy of the printout of your .java file.
    �     � A diskette labelled with your name, group, student ID. The diskette should contain ALL the necessary files (.java, .html, and .class)
    to run your applet.
    �     � The above in an envelope topped with the Assignment Completion Report (see pages 6, 7 & 8). Page 6 is for you to paste on top
    of your envelope whilst pages 7 and 8 are for you to document your Test Plan, and write your comments (including any
    special instructions to run your program) - to be inserted into the envelope.
    In your .java program, you are to include a blocked comment at the top stating:
    q     q Your name, group, student ID.
    q     q Assumptions (if any) or any deviations from the specified requirements.
    q     q Any features that you would like to highlight.
    6.     5. WALK-THROUGH OF PROGRAM
    Monday 25th February at 9:30 a.m. SHARP
    In the walk-through, you will be asked to give short, written answers to some questions about your program. These questions will assess
    your basic understanding of the code that you are handing in. If you fail to display adequate understanding of your own program, you can
    be down-graded by up to two letter grades from what you would have normally received. It is also possible that you will be called to
    perform a demonstration cum explanation of your work if it is suspected that you have copied someone else�s work. Lesson: do your own
    work and you will have no problem!
    7.     6. GRADING CRITERIA FOR PROGRAMMING
    Correct and robust implementation of basic features     55 %
    Additional features     20 %
    Programming style:�     � Program design�     � Appropriate use of arrays�     � Appropriate use of variables, methods, and parameters�     � Proper usage of control structures (e.g. if/else, loops)     15 %

  • Will Apple help me with this issue?

    Dear Sir or Madam，
    I am a student in China, I really need your help, my iphone now problems bothers me! HELP ME PLEASE!!!
    As I bought my iPhone 4s(16GB,White) in the USA from Sprint, full price with tax,  unlocked ,it was excepted to be a global phone. But now I come across with some problems in China  using local carrier.Now I am in China, not the normal use of the phone, I rely on odd jobs to earn, very not easy, English is not my mother tongue, maybe there are many grammatical mistakes, I hope you'll forgive me! Mobile phone can not be used normally I am very sad, I can not contact the parents and friends, can not let them worry about me, I've tried all means, including the upgrade to 6.1, but still can not solve the problem, I think maybe I am in China, so can not be used normally, at this moment I am very anxious, because of the time difference, it is later I can send mail, you can see it, please help me, a Chinese student's request!
    I tried all the possible solutions from the Internet, and the Official solution offered by Apple (http://support.apple.com/kb/TS4459), but it doesn't seem to work.
    Will Apple help me with this issue? Please do.THANK YOU VERY MUCH!!!

    We are not Apple, and Apple does not unlock phones. Sprint will unlock phones, but you have to qualify. One of the qualifications is to have been a customer in good standing for a period of time. You can check their website for what that is. After that, they can unlock the GSM side of the phone for International use, that is it. If you are on a CDMA carrier, then it cannot be unlocked. Are you trying to use a local SIM card in China?
    Your only option is to contact Sprint to see if you qualify for an unlock. Only they can unlock it. Sprint is one of the poorest choices to take to another country.

  • Help required with upgrading to OS5 on curve 8520

    Hello everyone,
    I'm using an unlocked version of the bb curve 8520 and want to upgrade my bb device os to v5.0. (current version- 4.6.1)
    I tried using the application loader on the bb website (NA & India both) but it just tells me that my OS is updated and that i will be notified if there are any updates available. I would be really grateful if someone could help me update my os.
    Solved!
    Go to Solution.

    Hello,
    Your warranty is not endangered. You are free to use any carriers OS package on your BB. Your carrier may, however, refuse to provide you with support (including Warranty evaluation/service) until you fall back to their supported device OS level. But your warranty per se is not endangered.
    Good luck!
