I've inherited a complex shell script running on OSX that gets run on a crontab. Within the script I would like to periodically read everything in the terminal window and write it to another file... sort of as a log file that I can review later.
Im trying to capture things that have been ECHO'd within the script as well as any error messages displayed on the terminal. (ie /Users/topher/program.sh: line 58: Permission denied)
Is this possible? What command can read from the terminal or output of the program?
