I want to get out put as folows:
to start with I have a input file (inputfile.txt) that contains following data:
and file1.txt & file2.txt are in the current directory. there is a chance that they file may not exist.
I tried for loop, wc -l, grep, cut but the out put is not very satis factory.
Don't hesitate to give me any go-to or pointer to finding the solution. I don't expect you to do my work ;-)
100 HE01 {number of line in this file} {file created on time stamp}
200 LTXS {number of line in this file} {file created on time stamp}
(if the file does not exist then it should say FILE NOT AVAILABLEto start with I have a input file (inputfile.txt) that contains following data:
100 HE01 file1.txt 200 LTXS file2.txt
and file1.txt & file2.txt are in the current directory. there is a chance that they file may not exist.

#!/bin/ksh
cat inputfile.txt|while read v w x
do
if [ -e $x ]
then
num_lines=`wc -l $x|sed -e 's/ *//' -e 's/ .*$//'`
time_stamp=`ls -l $x|awk '{print $6 "_" $7 "_" $8}'`
echo "$v $w $x $num_lines $time_stamp"
fi
done
That will give you output like this (when both files exist - either one would just not do anything if they weren't there)
100 HE01 file1.txt 3 Oct_25_22:27
200 LTXS file2.txt 12 Oct_25_22:27
Hope that helps

Thank you Mike,
This was perfect. This is exactly what I was looking for!
I guess I cannot thank you enough :-)

Pick your poison, I guess - cat or redirect STDIN.
Thanks for the alternative suggestion

Mike (eggi),
your suggestion is correct. I hit this bug with the cat option: http://osdir.com/ml/shells.bash.bugs.../msg00023.html
Some how if you cat and pipe then the varibales are all converted to local variables within the while loop. I had to use the redirect input to over come the issue: Here is how I did it finally:

Cool - that's good to know. I've never hit that bug, but I'll be sure not to now
BTW, Credit GhostDog with the suggestion to redirect, I suggested using cat, so I don't deserve the thanks - but it's the thought, or gesture, that counts
Take it easy
