filesize from a file which has the list of files.
i have a file myfile. it has the below entries
/temp/firstfile
/temp/secondfile
and many more..

okay, now, i want to addup all the space occupied by this file

hmmm, but i met with a problem in getting each file out.
i did a silly command like more myfile | grep temp | ls -ltr

and it failed me....

any help. thanks!

This should work.

files=`cat myfile`
total=0
for i in $files
do
size=`ls -l $i| awk '{print $5}'|sed 's/ //g'`
total=`expr $total + $size`
done
echo $total

I think there is a way with a single ls | awk but can't remember how to do it off the top of my head.

Here's a different way:

l -a `cat myfile` | awk '{total += $5} END {print total}'

If you want to store the total in a variable:

files=`cat myfile`
total=`l -a $files | awk '{total += $5} END {print total}'`
