Since it seems you are looking for a theory, and not code...
One approach to how a script could pause would be:
Code:
LOOP:
Do your stuff
Check to see if file exists
If so, then wait for something to happen
(such as, keystroke entry or file to be deleted)
goto LOOP
Thus, if the file does not exist - say PauseMyProgram.txt - then you will continue with the LOOP'ing. So if you want to pause your script, simply create the file PauseMyProgram.txt and your script will wait until you satisfy your next requirement.
I guess I posted in wrong forum before. How do I pause another process and then restart it on linux? The other process doesn't listen for anything.
Thanks for any help you can offer.

The problem that I'm having is that I do not know how large the rsync'ed zip file is going to be. Right now I'm using a sleep command before I... (4 Replies)

I recently would like to write a shell script that

All,
Is there some way to have my KSH script pause, until the word "DONE!" appears in the logfile /logs/log.txt?
Difficulty: The word "DONE!" may already be present in logs from the past. So I anticipate tail -0f may (somehow?) need to be done in the background, instead of grepping in a... (16 Replies)

pause
pause(2) System Calls pause(2)NAME
pause - suspend process until signal
SYNOPSIS
#include <unistd.h>
int pause(void);
DESCRIPTION
The pause() function suspends the calling process until it receives a signal. The signal must be one that is not currently set to be
ignored by the calling process.
If the signal causes termination of the calling process, pause() does not return.
If the signal is caught by the calling process and control is returned from the signal-catching function (see signal(3C)), the calling
process resumes execution from the point of suspension.
RETURN VALUES
Since pause() suspends thread execution indefinitely unless interrupted by a signal, there is no successful completion return value. If
interrupted, it returns -1 and sets errno to indicate the error.
ERRORS
The pause() function will fail if:
EINTR A signal is caught by the calling process and control is returned from the signal-catching function.
