howto catch output of bashinstruction
 

Hello,

I have made a small script for a backup routine, if i run in manualy it goes fine but when i put in a cron, there is a part that goes wrong.
I am 7 zipping a directory but thats failing, since 7 zip does not has his own log file i can't check the problem.
When i run the 7z instruction manualy it goes fine and 7z displays what he is doing in the shell, so what i want to do is catch the output 7z generating while called by cron.

Thx

Redirection is your friend....

capture the normal output of the command into a file:
command [arguments and stuff] > logfile

capture the errors into a file:
command [arguments and stuff] 2> logfile


To do both:
command [arguments and stuff] &> logfile
