Hi,

that looks like it wouldn't even work on the command line. How about the following:

Code:

/home/devin/Desktop/bla.sh 2>&1 | /bin/gzip - > /home/devin/Desktop/bla.log.gz

Oops, you actually explicitly asked why it wouldn't work. Hmm..

Firstly you have "&>" which will background the process and send the stdout to the file /home/devin/Desktop/bla.log (Perhaps you wanted ">&" or "2>&1" which will send stderr to stdout). Next you have a pipe, "|" to "exec /bin/gzip"... there a number of issues here. Why the "exec"? And gzip will only take stdin as input if given "-" as the input file etc, and you've already redirected the output of your script to bla.log.

HTH,

Evo2.

yes, you can but it depends on the size of that file. See the man page of mailx: http://linux.die.net/man/1/mailx, you can try something like this:
echo "this is the log file of ... at ...." | mailx -s <subject> -a <attachment> <your address>
