In one of my OS X scripts, I used the following to check the running process.
ps -aux | grep '/etc/bkupexec/agent.be'
However, it doesn’t always work. I didn’t know exactly why. On one occasion, I found that if I run the script in a wide window and it works every time. I knew that it’s related to the window size then. How do I set it so that the script runs regardless the window size. The answer is right in the manual page.
-w Use 132 columns to display information, instead of the default which is your window size. If the -w option is specified more than once, ps will use as many columns as necessary without regard for your window size.
After I changed the script to
ps -auxww | grep '/etc/bkupexec/agent.be'
, it runs flawlessly every time.
