I tried your command but it didn't work. Guess it would've helped if I specified on what type Unix system I was trying to use this on: AIX 5.X Not sure if it makes a difference though. Appreciate if you can let me know whether I can use it still or should I try something different. Thanks for your quick reply, Dan.
I'm doing a script with the Shell. I need that it only show the number of running processes.
Ex:
echo "There are `command` running processes"
Thnx!

Hi All,
Is there a way in which a long running command can terminate by itself inside a script? I need something like below:
echo Start
<command>
exit
If the <command> is taking more than say 100 seconds to complete, the script should exit without manual intervention.
Thanks,

Hi All, Need an urgent help, I have a requirement to find long running unix processes.. I have tried the below commands, but not succeed. I need to arrange the unix processess in an order of elapsed time (high to low) that runs in a system.

The end result that I'd like is to terminate any process on my ps -u username list that extends beyond 20 minutes. I know for a fact that this process will be named l.exe, but I don't know the number in between and I won't know the PID. Is there a way to use grep or pidof to do this task every 20... (2 Replies)
Hi,
I need a script to kill the process if it running for long time.
Inputs for the scripts:
1.test.sh (will be running fron cron scheduler)
2.1 hr (ie threshold_time - if the test.sh is running for more than 1 hr test.sh has to kill)
Thanks,

shell-quote
SHELL-QUOTE(1) User Contributed Perl Documentation SHELL-QUOTE(1)NAME
shell-quote - quote arguments for safe use, unmodified in a shell command
SYNOPSIS
shell-quote [switch]... arg...
DESCRIPTION
shell-quote lets you pass arbitrary strings through the shell so that they won't be changed by the shell. This lets you process commands
or files with embedded white space or shell globbing characters safely. Here are a few examples.
EXAMPLES
ssh preserving args
When running a remote command with ssh, ssh doesn't preserve the separate arguments it receives. It just joins them with spaces and
passes them to "$SHELL -c". This doesn't work as intended:
ssh host touch 'hi there' # fails
It creates 2 files, hi and there. Instead, do this:
cmd=`shell-quote touch 'hi there'`
ssh host "$cmd"
This gives you just 1 file, hi there.
process find output
It's not ordinarily possible to process an arbitrary list of files output by find with a shell script. Anything you put in $IFS to
split up the output could legitimately be in a file's name. Here's how you can do it using shell-quote:
eval set -- `find -type f -print0 | xargs -0 shell-quote --`
debug shell scripts
shell-quote is better than echo for debugging shell scripts.
debug() {
[ -z "$debug" ] || shell-quote "debug:" "$@"
}
With echo you can't tell the difference between "debug 'foo bar'" and "debug foo bar", but with shell-quote you can.
save a command for later
shell-quote can be used to build up a shell command to run later. Say you want the user to be able to give you switches for a command
you're going to run. If you don't want the switches to be re-evaluated by the shell (which is usually a good idea, else there are
things the user can't pass through), you can do something like this:
user_switches=
while [ $# != 0 ]
do
case x$1 in
x--pass-through)
[ $# -gt 1 ] || die "need an argument for $1"
user_switches="$user_switches "`shell-quote -- "$2"`
shift;;
# process other switches
esac
shift
done
# later
eval "shell-quote some-command $user_switches my args"
OPTIONS --debug
Turn debugging on.
--help
Show the usage message and die.
--version
Show the version number and exit.
