Need a small script to grep file details from around 2000 files.

Hi,

I have a directory were printer definitions are stored there are more than 2000 printer definitions in it and each printer definition looks as below :-

root@segotl0269# cat qpl00361

* VPSX Printer definition file (QPL00361) *

NLSEQ = 0D0A
RETAIN = 7

=======================================

So i want to grep printer name starting with QFRxxx as prefix with IP address for that printer among 2000 printer definitions in the directory.

Thanks in Advance.

1. show some example output you want
2. looks like the filename is the same as the printer name, so search by filename then grep for the IP (I'm assuming you want the TCPHOST field).
3. write some code and test it; come back if you get stuck and show us your code.

In the meantime, you'll want these

Can't you simply grep it, as:

Code:

~$ grep 'QFR*' qpl00361

OR

~$ awk '/QFR/ && /TCPHOST/ {print $0}' qpl00361

And as Chris said, be little specific and show us some example, so people could suggest something helpful.

PS: Please use [code][code] around command and output that you share.

check out this thread:
http://www.linuxquestions.org/questi...e-grep-819347/

or you can use vi editor to search

vi qpl00361

:s/QFR/

Thanks Chris and Shiva for the suggestion and link..
Going through those :)
