Shell Programming and Scripting

Hello all,

I have the following 2 questions..

1) I would like to capture the output of an echo command to 2 different files at the same time. This does not seem to work. Any ideas?

echo ==== started on `date` ==== >> res1.log res2.log


2) Would it be possible to just get the 5th and 6th column of df -k output as listed below?

use% Mounted on

10 /d1
20 /d2

Thanks

Use awk to get it.

Code:

df -k | awk '{ print $5 "  " $6}'

What you want capture in 2 different files ?
You can use for loop with 2 iterations to echo to 2 different files.

Thanks Ynilesh for the quick response..I already tried using awk but as my df output is slightly different, I don't get the expected output as some of the FileSystem names are slightly longer.

df -k
