IF you are at the command line, CTRL-C will stop the command - unless watch is called from inside a shell script with SIGINT trapped. (bash or ksh trap command)
If watch is a separate process,
where pid == process id of the process will terminate the process.
On Linux I could use the `watch` command to loop a command X times. Is there a similar command on AIX? If not, is there a way to write a loop on the command line to do this?
Linux: watch -d -n 60 'db2 list applications show detail | grep Connect | wc -l'
AIX: ??? (2 Replies)

Hi there,
I was wondering if there was a way in UNIX that I could set up a running script that monitors a certain folder (and all the folders and files contained within it) so that if any file changes then it will be the change logged within a log file. I dont know if this is possible in Unix... (6 Replies)
Hi all,
I am trying to create a file that shows the CPU usage, constantly updating (similar to TOP).
So far i have a file (called test) containing:

and then I ran the command:

WATCH(1) Linux User's Manual WATCH(1)NAME
watch - execute a program periodically, showing output fullscreen
SYNOPSIS
watch [-dhvt] [-n <seconds>] [--differences[=cumulative]] [--help] [--interval=<seconds>] [--no-title] [--version] <command>
DESCRIPTION
watch runs command repeatedly, displaying its output (the first screenfull). This allows you to watch the program output change over time.
By default, the program is run every 2 seconds; use -n or --interval to specify a different interval.
The -d or --differences flag will highlight the differences between successive updates. The --cumulative option makes highlighting
"sticky", presenting a running display of all positions that have ever changed. The -t or --no-title option turns off the header showing
the interval, command, and current time at the top of the display, as well as the following blank line.
watch will run until interrupted.
NOTE
Note that command is given to "sh -c" which means that you may need to use extra quoting to get the desired effect.
Note that POSIX option processing is used (i.e., option processing stops at the first non-option argument). This means that flags after
command don't get interpreted by watch itself.
EXAMPLES
To watch for mail, you might do
watch -n 60 from
To watch the contents of a directory change, you could use
watch -d ls -l
If you're only interested in files owned by user joe, you might use
watch -d 'ls -l | fgrep joe'
To see the effects of quoting, try these out
watch echo $$
watch echo '$$'
watch echo "'"'$$'"'"
You can watch for your administrator to install the latest kernel with
watch uname -r
(Just kidding.)
BUGS
Upon terminal resize, the screen will not be correctly repainted until the next scheduled update. All --differences highlighting is lost
on that update as well.
Non-printing characters are stripped from program output. Use "cat -v" as part of the command pipeline if you want to see them.
