Top Forums Shell Programming and Scripting Question about Shell Programming Post 18221 by LivinFree on Tuesday 26th of March 2002 03:22:10 AM

Cleaning up, in many cases that I've seen in shell scripting, means removing any temp files, unsetting any variables that may make it into a shell session (doesn't happen all that often - most scripts are run as a child process, as opposed to "sourced", or run as a string of commands in the current process), and handling signals properly (if the job runs as a daemon, does it ignore the SIGHUP signal correctly? What does the script do when it hits an error, or something it doesn't know how to deal with?).
Any other things to watch out for, anyone?
