What is the best way to minimize the new line in order to search the items in a big file.
Code:
perl -lne '$x=" "; /(crash_report_\d+)/ && ($x = "$1 "); while(/(generate_check_\d+)/g){ $x .= "$1 " }; ($x !~ /^\s+$/) && print $x' file

This User Gave Thanks to balajesuri For This Post:

Yes Balajesuari....

It works....

What i observe it search for crash_report_ and generate_check_

How about seraching only for crash_ and generate_

I think the script needs to undergo with some changes for this.Can you tell me what changes are required.

Observe the two regular expressions
1. /(crash_report__\d+)/
2. /(generate_check_\d+)/

You may make desired changes to these two regular expressions as required.
