UNIX for Dummies Questions & Answers

Hi,

I have a very large file that contains a listing of all files on the system. I need to create a listing from that file of all files that start with the following format: s???_*, whereas the '?' represents characters, so the file name begins with an 's' followed by three other characters and then an 'underscore', ie soap_box.dat. I've tried a variety of find, grep and awk commands but not getting the results I need. Tried looking at the man pages but must not be getting the correct format of the commands. Thank you.

Can you post few starting lines of that file?

Basically a listing as if you did an 'ls -l command

/input/288383/test/soap_box.dat
/input/393939/test/stan_man.dat
/input/238280/test/pick_up.dat
etc.

lists all files from top directory down through the tree.

Try:

Code:

egrep '/s..._[^/]+$' file

Thank you, it worked!
