`ps -ax` gets cut off when run from cron

Carl Lerche

Hello,

I have a simple ruby script that writes the content of `ps -ax` to a
file, when I call it myself, it runs fine, however when I set the
script in a cron job and cron calls it, the output is truncated at 80
characters, which is quite annoying. Any ideas as to why this is? I
have my PATH set in the crontab:

PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

Thanks,
Carl Lerche

Code? Remember that cron jobs run in a different environment, often with
different permissions.

Try `ps -axwww` instead.

Hey, that did it! Dumb of me not to check the man pages for ps...
didn't think of it.

Thanks for the help!
