redirecting output in bash scripts

s_siouris · 05-13-2006, 06:32 AM

Hi all,
I have a bash script and I know how to redirect output to either the screen or file. What I am looking for though is to have the output on both screen and file. I have seen the the "tee" command might be what I want, but I haven't managed to get it working.

Any ideas on how to do this?

An example for tee:

Code:

pu@slackw:~$ echo "test output" | tee outputfile
test output
pu@slackw:~$ cat outputfile
test output
pu@slackw:~$

So basically just run your script with

Code:

 ./myscript | tee outputfile

great! this is what I want, thanks.

is there any way of including this in the script so that I only type "./myscript" ? I was thinking of some combination with "set" and "tee" (inside the sript)

cheers for your help

I'd suggest a wrapper script, i.e. myscript is "./mysubscript | tee outputfile". This way you can run the script either with or without tee.
