In a simplified format...can be optimized..

Assuming you have redirected the o/p of the first command to a file name "file".

Code:
#!/bin/sh

while read line
do
first=$( echo $line | cut -c 1 )
if [ $first == "/" ]; then
  echo $line
fi
done < file


cheers,

consider that you are redirected your output of the first command to a file called output1

So the content of the output1 file will be as follows

Code:
release.label.2010.03.02
objects:
/project/path/to/some/file_name.ksh
/project/path/another/file_name01.dat

To extract the files from that you can use the following commands

Code:
cat test | grep "^/.*\.*" test

So now it will extract the file names from that output and will give the following as the result
Code:
/project/path/to/some/file_name.ksh
/project/path/another/file_name01.dat

Now you can pass the above result to the third command using pipe

i was trying that but was told not to create any files. So now i put the output in a variable.
I tried this code using Devtakh's idea & it worked:
Code:
for v in ${var1}
do
   first=$( echo $v | cut -c 1 )
   if [ $first == "/" ]; then
        mycommand $v
   fi
done

Thanks people. Smilie
