Read and Edit Text Files

I wanted to find out if there is a way to read linux
configuration files, edit parameters in them and save them using
coldfusion. I know PHP has the capability to do this, but I don't
know if CF does and how powerful it is.

If it's plain text, just write it into a textarea and let
your users edit it there. When they submit, use cffile to overwrite
the text file.
There are other ways to allow users to edit text in a web
app, such as the "contenteditable" attribute in IE, but the basic
idea remains the same.
Or do you mean that the app will alter the files
automatically? If that's the case, then regular expressions would
likely be the way to go.

Read and Write Text Files

How do I add text from an input text box from flash to a text

have an:
on (release) {
//script
Lets say the URL is "/scene_detail.doc". I can also use .txt
files, but I'd much prefer someone to tell me how to do this with
DOC files. Thanks in Advanced!

Flash cannot write files. You must have some sort of
serverside script do
this, something like ColdFusion, php, asp, perl or cgi.
There is a sample here that writes to an XML file with php:

Here is one that writes to a text file with perl:

Will PS express on Win.8.1 read and edit a PSD file?

Hi, I am trying to find a reliable program to open PSD files for a business card i have had created. I may want to change the verbage around on the template. I searched the microsoft store for programs and PH express came up but did not describe if the program will read and edit PSD files.
Can anyone provide some feed back on this?
Or provide another option besides purchasing PS?
Thank you.

Updated: i installed PS express and shocker... it doesnt evan acknowledge the PSD file in my folder.
so i read somewhere that i may be able to edit a PSD with an older version of photshop., but i am running Win. 8.1 ...
can someone suggest a older more echonomical version of PS that will read and edit PSDs???
need help... thank you.

HOW TO WRITE AND READ FROM A TEXT FILE???

How can I read from a text file and then display the contents in a JTextArea??????
Also how can I write the contents of a JTextArea to a text file.
Extra Question::::::: Is it possible to write records to a text file. If you have not idea what I am talking about then ignore it.
Manny thanks,
your help is much appreciated though you don't know it!

Do 3 things.
-- Look through the API at the java.io package.
-- Search previous posts for "read write from text file"
-- Search java.sun.com for information on the java.io package.
That should clear just about everything up. If you have more specific problems, feel free to come back and post them.

Help with reading in a text file and arrays

I need to read in a text file with info like this for example
dave
martha
dave
billy
I can read the information into an array and display the names but what I need to do is display how many times the same name is in the file for example the output should be
dave 2
martha 1
billy 1
How can I accomplish this? Would I use a Compareto Method to find
duplicate names?

Hi,
I would recommend storing them in a Hashtable.. something like this:
Hashtable names = new Hashtable() ;
String s ;
while( ( s = bufferedReader.readLine() ) != null ) {
    if ( names.contains( s ) ) {
       names.put( s , new Integer( names.get(s)+1 ) ) ;
    else {
       names.put( s , new Integer( 1 ) ) ;
}Then the hashtable will contain a set of keys and values, which are the names and counts respectively.

Read and write from and to text file

Hi All,
I am trying to read some portion of a text file and make measurement and calculation with those numbers and write back to the same text file and also to a excel file. I need to create a 2 D array of 20 by 20 from the text file values and write to front panel table and to text file. but I am having problem with it, obviously I am new to this. Please help me. thanks much
~ Johnny

Hi Lynn,
the requirement is to move C1 and C2 to each position that is given in the text file in steps and percentage value.
for example C1 has to go to first step (5%) and C2 has to go thru all steps, 5% to 95% , in 5 percent increment.
each 100 steps translates to 1 percent increment in the capacitor value.
at the end, I need to enter the measured data (values of C1 for each step, vesus all values of C2 for all steps) and enter them at the bottom of the text file's table where it starts at : "IMPEDANCE_REAL in Ohmone line per C1 position, containing all values for the different C2 positions" and do the same for where it says "IMPEDANCE_IMAGINARY in Ohmone line per C1 position, containing all values for the different C2 positions"
the reason I read the file twice, is that if it read it once, I couldn't connect it to spreadsheet string to array vi.
as you can see, I also like to use the write to measurement file and build table express vi's to display the table on the front panel and save the data to ni data file format so later I convert it to excel too.
any thoughts?
thanks for your help

Reading through a text file and then sorting

I'm having a lot of problems with this.
I have to read through a text file and I have to split the string up so that it is seperated into individual tokens. A line from the text file looks like this. addEvent(new Bell(tm + 9000)). I have to grab the addEvent, new, Bell, tm and 9000 and store it in a linkedlist. After reading through the whole text file I have to sort the the linked list based on the number. ie: 9000. Is there any way to do this? I currently break up the text file using a StringTokenizer object but then i am uncertain on how to add it to a linked list and then sort each line based on the number. Any help would be appreciated.
Joe

Sorry to bother you Ben but I just can't get my head wrapped around this. Here is exactly what I have to do:
After reading, Events must be stored in the EventSet according to the time they are to occur. Assume that no time number is more than 8 digits long. Restart() must be able to deal appropriately with any order of the Events. To accomplish this have Restart() save the relevant Event information in an LinkedList of strings and sort the Events by time before adding each event to EventSet. Use the <list>.add() to set up your linked list. This is shown in c09:List1.java and Collections.sort(<list>) shown in c09:ListSortSearch. Modify the Bell() to output a single "Bing!". When you read in a Bell event generate the appropriate number of Bell events as indicated by rings. These must be set to the correct times. This is an alternative to generating the new Bell events within Bell(). It will allow them be sorted into their correct time sequence. At this point the output of the program should be identical the original program.
After the intitial start, when restarting Restart() must provide to the user the option to recreate the EventSet from the linked list or read in a new file (supplied by the user). This must be achieved by prompting the user at the console. Please also allow the user the option to quit the program at this stage.

Help needed regarding reading in a text file and tokenizing strings.

Hello, I require help with a task I've been set, which asks me to read in a text file, and check the contents for errors. The text file contains lines as follows.
surname:forename:1234:01-02-06
I can read in the file, but dont know how to split the strings so each token can be tested (ie numbers in the name tokens)
However, I am not allowed to use regex functions, only those found in java.io.*
I think i should be putting the tokens into an array, but have had no luck so far in doing so. Any help would be appreciated.

public class Validator {
     public static void main(String args[]) {
          String string = "Suname:Forename:1234:01_02-06";
          String stringArray[] = string.split(":");
          System.out.println (validateLetters(stringArray[0]));//returns true
          System.out.println (validateNumbers(stringArray[3]));//returns false
     static boolean validateLetters(String s) {
             for(int i = 0; i < s.length(); i++) {
             char c = s.charAt(i);
             if ((c < 'A' || c > 'Z') && (c < 'a' || c > 'z')) {
                     return false; //return false if one of characters is other than a-z A-Z
             }//end if
             }//end for
             return true;
     }//end validateLetters
     static boolean validateNumbers(String s) {
             for(int i = 0; i < s.length(); i++) {
             char c = s.charAt(i);
             if ((c < '0' || c > '9') && (c != '-')) {
                     return false; //return false if one of characters is other than 0-9 or -

Read and Edit a PDF File

Dear Friends,
I would like to know if it is possible to read and edit the same pdf file using Java. ie my PDF file named "Sample.pdf" has contents like
First Name = &F_NAME
Last Name =&L_NAME
what I want is to parse the Sample.pdf file and look for &F_NAME and replace it with "Jacob" and &L_NAME and replace it with "Abraham" so that the contents within that pdf file look like
First Name = Jacob
Last Name =Abraham
Please let me know if it is possible to do like this. All suggestions are welcome. Thanks in advance.

Read in a text file and parse at spaces

I need to read in a text file, then split it at the spaces (after each word)
then I would like to save each sentence (maybe as a String Buffer)
(chek each word to see if a .?! is at the end to determine the end of a sentence)
Then I need to add the word END to the end of the StringBuffer
then store each sentence as an element in an arrayList.
Please Help.

Cant you just store the entire text file into a really big String, then split it at each "."?
String text = "";
//read file into text
String[] sentences = text.split(".");

Remotely editing text files in Windows WinRM/PSExec/Powershell/cmd

Hi!
How can I remotely edit a text file in Windows?
I am running and administering a number of Windows 7 workstations and Windows Server 2012 machines. I would like to be able to remotely edit text files on any of these machines. I can connect to any of these machines via psexec or powershell remoting. I
can also connect via rdp, but for the workstations I would rather not kick the user off unless I absolutely have to.
For example, we manage state configuration using
Salt. Local configuration files are stored in C:/salt/conf. I would like to be able to edit these config files on the fly.
This question on Stack Overflow covers the same topic, but none of the answers are particularly satisfying. Some of the possible solutions
are:
Remote Desktop: as I say, I would rather not have to kick a user off their workstation
Edit a file over a UNC path: this only works for files on a share, and setting up arbitrary shares for quick edits seems like a bad idea.
Install some manner of ftp or ssh server on all the target computers. This would certainly work, but it is it necessary with WinRM already active? I feel like installing and configuring extra software across all the machines in my organisation would be
a last resort.
Edit with a command line editor (e.g. vim, emacs) over a remote powershell session. This doesn't work. I don't understand the technical details, but a powershell remote session isn't interactive in the same way that ssh connections are.
Edit using powershell's -replace operator, out-file and add-content cmdlets. This works, but is hardly the same as a fully featured text editor.
Retrieve content from the remote, edit locally, and post back to the remote. This works, and is arguably the best solution I've found. Code sample from SO:
PS C:\Users\Meredith> Invoke-Command -Session $ps -ScriptBlock {get-content c:/inetpub/myapp/web.config} > web.config
edit web config
PS C:\Users\Meredith> get-content web.config | Invoke-Command -Session $ps -ScriptBlock {set-content c:/inetpub/myapp/web.config}
The last two options are the workflow that I've been using for now. Regex replacement for very simple changes, and copying to local and editing there for more complicated ones. Neither is ideal, but they work. It just feels incredibly old fashioned.
I'm considering writing a plugin to my editor of choice (vim) to perform the remote fetch and save, to make my workflow a little bit smoother. Before I try that, I just want to know if there's anything that I've missed, or misunderstood.
Cheers

What is the "redirector"?
I posted the same question to Stack Overflow, and was told about administrative shares. I wasn't aware of this, and it's exactly what I wanted. I can open the filetree of a remote machine with the path \\machinename\c$\. Perfectly simple, now that I know
the answer.

How to read from a text file one character at a time?

Some additional comments:
You really don't want to read any file one character at a time, because it is highly inefficient. More typically, you read the entire file into memory with one operation (or at least a large chunk, if the file is gigantic) and then do the rest of the operations in memory. One easy way to analyze it one byte at a time would be to use "string to byte array" and then autoindex into a FOR loop, for example.
Of course you could also read the file directly as a U8 array instead of a string.
