Solaris 11 - run a simple BASH script on computer startup

I need to have a simple BASH script run on my Solaris 11 machine automatically whenever the computer (re)starts. It should be run with root permissions and after the computer has fully booted. What is the easiest way to do that?
Thank you
Dusan

Hi user9368043
Yes, that should be right, and be intended this way.
See /etc/rc3.d/README and the following part from smf(5):
Legacy Startup Scripts
Startup programs in the /etc/rc?.d directories are executed
as part of the corresponding run-level milestone:
/etc/rcS.d milestone/single-user:default
/etc/rc2.d milestone/multi-user:default
/etc/rc3.d milestone/multi-user-server:default
Your question concerning upgrading to Solaris 11.1:
In the Gnome menus, you should look for (and start)
System --> Administration --> Update Manager
Let it do its work. It will give you a new boot environment, containing Solaris 11.1. Possibly, you have to perform upgrading twice. With "beadm activate", see beadm(1M), you can go back to Solaris 11.0 whenever you want.
"Local" parts of your zfs root pool, like /usr/local, home directories, /root, and so on, should be in separated file systems, and be mounted outside the root pool before upgrading. They are availlable then from any boot environment, and will not be duplicated. See more in zfs(1M), zpool(1M).
I strongly recommend upgrading. Solaris 11.1 is great.

Simple BASH script to update subversion files

This is just a simple BASH script that will update all .svn files in a specified directory. If an update fails, it will attempt to update all the subdirectories in the failed one, so as much will be updated as possible. Theoretically, you should be able to supply this script with only your root directory ( / ), and all the .svn files on your computer will be updated.

Simple bash scripting help needed..

I want to learn som simple bash scripting in order to automate various tasks.. Im totally noob, so bear with me
First of all I would like to set configs without using nano.. is there a simple command for this? For example if i want change my hostname in /etc/rc.conf.. how can i print the current vallue and how can i change it`?
i was thinking something like this to get the current value:
# cat /etc/rc.conf | grep HOSTNAME=
which returns HOSTNAME="myhostname"
how can i change this value with one or more commands whitout touching the rest of the file?

A slightly naive solution:
CHOICE="lisa"

if [ "`echo \" $NAMES \" | grep \" $CHOICE \"`" ]; then
echo "this is how you do it"
fi
The extra spaces inside the escaped quotes are to ensure that only a whole word is "matched".
You can also replace the elif's with a loop through a list of "the other variables". Then you'd use the loop variable instead of $CHOICE above.
grep can check on word-bounderies with \< and \>, or with the -w switch. The -q switch suppresses any messages and exits with exit-code 0 when the first match is found:
if echo "${NAMES}" | grep -qw "${CHOICE}"; then
Nice and readable, should work, but i haven't tested it
EDIT:
Procyon wrote:CHOICE="lisa"
NAMES="homer marge lisa bart maggie"
if [[ $NAMES =~ $CHOICE ]]; then echo match; fi
This one also matches elisa, ie. no check on word bounderies. You should be carefull with that

Running a simple shell script

Not being a regular user of terminal on OSX, I have managed to forget how to run a simple shell script. The purpose of the script is to rename a set of files contained in a specific directory. Here is a sample of the script I wrote some time back:
mv product_22.jpg 080688614423.jpg
This command repeats for each file I need to rename. My recollection is that I simply put the actual script text file in the same directory as the images to be renamed and drag the script file into a new terminal window and hit enter to run. When I try this however I receive the following error:
ord2: Permission denied
Can anyone help me out here? I'm running 10.2.8. I seem to beforgetting a critical step somewhere along the way.
Thanks
Mac OS X (10.2.x)

Have you set the execution bit for the script? When not, use: chmod 755 script.

Solaris sends SIGKILL to bash script?

I have this bash script that just loops forever (until stopped), it outputs data to files and runs various other commands to display information on the terminal. The problem I'm having is that solaris seems to send SIGKILL to this script after it's been running for a period of time. Typically a few hours. As far as I can tell there's doesn't appear to be anything obviously wrong with the script. Why would solaris send a SIGKILL?? I know it's a sigkill from the exit code 137.
Anyone have any suggestions?? I'm running Solaris 8.
Thanks

No idea, it doesn't really make sense.
You could check if there is anything in crontab or similar which kills processes of idle users, but thats a bit of a long-shoot.
Make your script log to a file frequently, so you can figure out when to determine if its always around the same time, and in which part of the script.
If Solaris would send it a kill signal it wouldn't be SIGKILL.

Running java in Bash script

Hi all,
I need to run a bash script in Linux which will then run a java program. I managed to run the script successfully (and running the java program eventually) by doing ./myScript. However, when my script is being called by some other programs, the java program doesn't run. I've check the classpath and path, seems everything is in place. I tried having this :
java myjavaProg
in myScript, it doesn't work.
I also tried this, it doesn't work as well :
java -classpath /usr/local/nagios/libexec myjavaProg
Anyone has any idea why? Thanks in advance.

I'd suggest editing your bash script, replacing the java call with one that invokes a class with a clearer sense of what it's doing. I mean, write a small class that creates a file in /tmp or something, so you can be more sure whether or not it's being invoked.
Perhaps your java program is running, but it's behaving differently in these circumstances.

Why does do shell work differntly from running the same bash script in terminal?

i have the following a/s:
set scriptPath to quoted form of ((POSIX path of (path to me)) & lnThumb)       set ftn to ""      repeat           try                do shell script scriptPath & " " & ppath & " " & ftn                exit repeat           on error error_message number error_number                 if error_number is not -128 then                     set ftn to (choose file with prompt "select folder thumbnail" default location dir without invisibles)                     set ftn to quoted form of the POSIX path of ftn                end if           end try      end repeat
calling this bash script:
#!/bin/bash -f   cd "$1" rm ./folderthumb.jpg   if [ $# -gt 1 ] then      ft=${2/#"$1"\//} else      ft=$(awk '/folderIcon=/{printf("%s",$1)}' meta.properties | sed s/folderIcon=// )      if [ 0$ft -eq 0 ]       then          exit 1      fi      ft="thumbs/"$ft fi ln -s $ft ./folderthumb.jpg exit 0
which works as expected when run from the cli:
tomw> /Applications/imageProc/fixJAlbum.app/Contents/Resources/Scripts/lnThumb.sh `pwd` `pwd`/thumbs/P1040161.JPG   tomw> ls -l folderthumb.jpg lrwxr-xr-x 1 tomw admin 19 Oct 22 10:36 folderthumb.jpg -> thumbs/P1040161.JPG
but fails to strip the common directory when called from do shell:

[Systemd] - How to tell if a service is running in a bash script

I need a bash script to query systemd (systemctl or systemd or?) to see if a given service is running. Is there a way to do it talking to systemd directly, not by looking for a pid file or seeing if a process is running? Thank you.

Good point.
I'd say that, in the case of "RemainAfterExit=yes" services, it's not really black and white. The effects of the service are active, even if the service itself has exited, but it's up to the user to decide whether or not that's "running" in their opinion.

HOW DO I RUN A UNIX BASH SCRIPT FROM JAVA??

HI. Here's a tricky little problem i have. There's a unix bash script that has some commands in it, that manipulate a file. It appends a certain string variable to a file called users. The users file is an ordinary text file.
I know this script to work perfectly, when i invoke it like this directyl from the command line: ./addusers.sh
or even: bash /downloads/selinux/policy/addusers.sh
Now, i have a java program, and its meant to just execute that script. It doesnt throw any Exceptions at runtime. But when i look at the users file, and expect it to have an extra line that was the string variable, the file is UNTOUCHED!
Again, direct command line invocation works, but not from java. Here's what my invocation from java looks like:
Process p = Runtime.getRunTime().exec("bash downloads/selinux/policy/addusers.sh");
The strange thing is, i tried a different bash command. I tried:
Process p = Runtime.getRunTime().exec("mkdir /temporary");
and this worked!
so why not the other one??
I cant figure it out.

You say:
bash /downloads/selinux/policy/addusers.sh
And you say in Java:
Process p = Runtime.getRunTime().exec("bash
downloads/selinux/policy/addusers.sh");
As if a leading / would be missing from the Java
version...nyix says:>
...OK sorry about that. i DO have a / in front of the downloads.... section in the java method. So its:
Process p = Runtime.getRunTime().
exec("bash /downloads/selinux/policy/addusers.sh");
HELP please?

Another simple bash script to clean pacman cache

here is a simple script that I have written which cleans pacman cache folder in a way that only the packages which are now "updated" in the repositories, will get removed. This is different from what "pacman -Sc" does. pacman -Sc also removes any package which is not installed, while this script keeps all the packages which are updated whether they are installed or not.
The functionality is some how like what "apt-get autoclean" does in debian.
to use this script you need to run it with "list" or "clean" arguments. you can also use the "help" argument for more help.
I hope it helps

1. `echo -e 'foo\nbar\nbaz'` gets long and unreadable quickly. Instead, use here documents:
cat <<EOF
What should I do?
Valid Argument are "list", "clean" or "help"
EOF
2. Use a case command, looks cleaner:
case "$1" in
list) ... ;;
clean) ... ;;
help|-h|--hep) ... ;;
# Check if the user is sure!
echo "This might take a while based on the amount of cached packages."

then
echo "Exiting on user request"
exit 0
else
echo "Invalid answer"

Try:
read -p "hello: " -r
echo $REPLY
And again, `case` should be cleaner in this case.
# Process the packages
cd $DIR #change to cache directory.
pacman -Sl | awk '{ print $2" "$3; }' > $TMPFILE
While you quoted a lot, you left these two out. "$DIR" and "$TMPFILE" should be quoted, otherwise whitespaces will break the code.
for f in $(ls $DIR)
Apart from the same missing quotes, calling `ls` is a waste here. The following is sufficient and (maybe surprisingly) more accurate:
for f in *
How is it more accurate? Run this test script:
#!/bin/bash
DIR=/tmp/foo
mkdir -p "$DIR"
cd "$DIR"
touch a\ b c$'\n'd
for i in *; do
printf '+%s+\n' "$i"
done
printf '%s\n' ---
for i in $(ls $DIR); do
printf '+%s+\n' "$i"
done
Let's not go too far here. Just get the idea.
do
pname=$(file $f | cut -d: -f1) #Produces filename, like: fetchmail-6.3.19-1-i686.pkg.tar.xz"
Calling `file` here is, again, unnecessary. Also, filename of a package can contain ":", e.g., vi-1:050325-1-i686.pkg.tar.xz, which breaks your code.
Don't complicate things:
pname=$f
spname=$(echo $pname | sed 's/-[0-9][0-9]*.*//g') #removes package version: fetchmail
Broken for ntfs-3g-2011.4.12-1-i686.pkg.tar.xz, nvidia-173xx-utils-173.14.31-1-i686.pkg.tar.xz, etc... Something less lousy:
sed 's/$-[^-]\+$\{3\}$//' <<< "$pname"
pver=$(echo $pname | sed 's/.*-$[0-9\-\.][0-9\-\.]*-[0-9\-\.][0-9\-\.]*$.*/\1/g') #using pacman -Qi for all files takes a lot of time.
Although this might work for now, this would break if we had an architecture that starts with a digit, e.g. 686. Something less lousy:
sed 's/$.*$-$[^-]\+-[^-]\+$-[^-]\+$/\2/' <<< "$pname"
if [ $(echo $pver | grep '[^0-9\-\.\-\-]' | wc -l) != 0 ] #checks if package version is alright
then
pver=$(pacman -Qpi $f | grep Version | awk '{print $3}')
fi
Again, calling `wc` here is a waste. Anyway, why is this check necessary at all?
newpver=$(grep -e "^$spname " $TMPFILE | awk '{ print $2 }')
if [[ $newpver != $pver ]]
then
$ACTION $f
fi
done
rm -f $TMPFILE
echo "Outdated packages processed successfully!"
exit 0
The post is getting too long, so so much from me. If there's anything you don't understand yet, read bash(1).
If I sound harsh or anything, don't be discouraged. Just keep reading, keep improving.

Repcheck - A Simple Bash Script To Monitor Remote Repos Commits

Hello all,
I'm using a few git/svn packages from the AUR, and only recently realized that while to PKGBUILD itself is able to pull and build the latest version, the package version in the AUR will not update, unless a new PKGBUILD is pushed by the maintainer, and so my update monitor isn't aware of those remote updates.
I've looked for a convenient way to track such changes, but all I could find were "live" monitors that run constantly and check for updates in a given repo in a set interval.
It didn't fit my needs, so I wrote a script myself.
The script basically maintains a file containing repo address and current revision number (for SVN) or hash (for GIT).
Whenever an update operation is done, all remote hashes are compared to those stored in the file and if updates are found, a notification is sent.
In case of GIT repos, the script also tries to find corresponding AUR package (I couldn't find a standard for SVN addresses...).
It is up to the user to update currently installed version to latest remote version if he wants, script only displays notification.
Dependencies:
- bash
- git
- subversion
- libnotify
* EDIT *
Updated script in next post.

Simple bash script in SL to remove files

1. SL on MBP
2. launch Terminal
3. pico remove-files
4. in my script are two simple rm /path to file type statements
5. save file in user/bin directory
6. type name of command
7. get "command not found" error
no wonder 99.9999% of the world doesnt program - why doesnt this simple setup work right ?

Chris Chamberlain1 wrote:
just guessing, if it type ./remove-files this script works.
That's the traditional way to invoke a program or command file if its location is not in your path. If that file is in /usr/bin and /usr/bin is in your path, I'm not sure why your situation doesn't work. On my Mac the directory bin in /usr is owned by root:wheel. If yours is the same, how did you manage to create your script there without permission manipulations? What exactly did you mean when you first mentioned "save file in user/bin directory"? Did you really mean /usr/bin or something else? If you meant some other location, you might want to add that location to your path with this command:
PATH=yourotherdirectory:$PATH

IIRC you need spaces

between '[' and another character.
Edit: Got it.
current_state=cat /home/phil/.screen_state
This is plain wrong. I get 'Permission denied' too.
Try
current_state=$(cat /home/phil/.screen_state)

A bash script to backup system only with modified files

Hi,
I've made a simple bash script to exam which files are modified and needed to be backed up.
It will use:
1. the hash in Pacman's database (/var/lib/pacman/local/<pkg_ver>/files
2. if no hash in the database, calculate it by our self from cache (/var/cache/pacman/pkg/<pkg_ver>.pkg.tar.gz
3. if no cache found, compare build date and last modified date
4. otherwise, this file better be backed up.
Currently it will only print which files are needed to be backed up, but no backup actually happens. (dry run)
And it is only in early development stage, please be careful.
USAGE:
<the script name> <where to backup files, a directory> <the files, or directories, separated by space, that are going to be examined>...
Here is the code.
#!/bin/bash
# usage:
# $1: file to backup
function do_backup() {
echo
function smart_bak() {

Thanks for this script. Nice work.
Can we traverse the pacman.log backwards up and rollback each operation (including "installed" in this). Something like:
history=$(tail -n +$(grep -m 1 -n "$1" "$LOG" | cut -d ":" -f 1) "$LOG" | tac | grep -E "(upgraded|installed)" | cut -d " " -f 3-)
