A good start is to use find. If you want to do something to each of the files, then something like:

#!/bin/bash
for file in $(find $1 -type f -iname '*.c'); do
  (What to do with the files, replacing filename with $file)
done

[tpl]

or try grep: "ls -R |grep *.c"

[sdousley]

or try grep: "ls -R |grep *.c"

This would work if it was JUST the filenames that you wanted, but if you also wanted their location, then the find method would be preferable since it includes that information. iirc, ls -R simply shows each directory's list under the folder name eg:

folder:

file1
file2
file3

folder2:

file4
file5
file6

Hi ,
After getting all the .c files i will store it in a file and i have to read the file and get the names of the .c files one by one up to end of the file. How can i read one line at a time from a file.

If you use the find method i posted above, you dont need to post the file names out to a file, just include what you want done to the file in the loop.
