Run a bash script in debug mode, show output and save it on a file

Sends both stdout and stderr to the pipe which captures the data in the file 'out.test' and sends to stdout of tee (likely /dev/tty unless redirected). Works on Bourne, Korn and Bash shells.

Know a better way?

If you can do better, submit your command here.

What others think

just running set -x first accomplishes the same thing

or, add set -x within your script at the point you want to turn debugging on

Comment by nottings 221 weeks ago

Also debugging can be turned on at the top of the script when declaring the shell type: #!/bin/bash -x

Comment by hellspawn 221 weeks ago

thanks hellspawn! didn't know that, but it makes sense.

Comment by nottings 220 weeks and 6 days ago

Thanks chaps. Made a lot of people at my place very happy.

Comment by mccalni 218 weeks and 6 days ago

How is it debugging? Does is it just more verbose?

It would be cool if there was a "safe-mode" where it blocks all writes to devices.

Comment by matthewbauer 190 weeks ago

see

http://www.davidpashley.com/articles/writing-robust-shell-scripts.html

for tips for safer, more robust coding

Comment by nottings 131 weeks ago

Inside script "set -x" turns on debugging. "set +x" turns off debugging. Bash example:

set -x; ls; ps; set +x
