standard output redirect from script

njia_1 — Sun, 31 Jul 2005 21:04:52 GMT

Hi

I want a osiping running at backgrund all the time but redirect the standard output to a file so I can monitor it.

I tried this

# at now
osiping NSAPs 2>&1 /tmp/osiping.log
crtl D

but it is not working, the osiping is running but I see nothing in that file.

thanks
Nan

Hi,

Could you try using

osiping NSAPs >/tmp/osiping.log

for only redirecting standard output.

HTH,

You have to try as,

# osiping NSAPs 1>/tmp/osiping.log 2>&1 &

If you use & you can monitor log file in same terminal.

It will run into background and you can monitor it as,

# tail -f /tmp/osiping.log

Problem in your script is, you are redirecting standard error to standard output but did not redirect standart output to log file.

hth.
