When I say

cat pnm.txt > trace.txt

It sends output of  the command to a file trace.txt.
is there any way to send the command
'cat pnm.txt'
to a file. ?

Hi

   echo "cat pnm.txt" > file.txt

   will create a file named file.txt with the
  contents "cat pnm.txt"

Thanks for your suggestion. I already know that. I'm looking for some way by which I'll be able to execute the command as well as spool it to a file.

On ksh
It sends the output of 'cat pnm.txt' to the file trace.txt.
It doesn't send "cat pnm.txt" to the trace.txt

hmm, do you need:
   echo "cat pnm.txt"|awk '{printf "echo %s >trace.txt\n",$0; print $0;}'|sh

Thanks all !!!

I didn't find the exact solution what I was looking for. I guess unix doesn't provide such simple option.

"ahoffmann"'s answer is more close to what I was looking for.
