Shell Programming and Scripting

Good evening All,

I have a perl script to pull out all occurrences of a files beginning with xx and ending in .p. I will then loop through all 1K files in a directory. I can grep for xx*.p files but it gives me the entire line. I wish to output to a single colum with only the hits found. This script needs to search for more than one occurrence per line regardless of the position or surrounding text.

Desired output:

Code:

xx1.p
xx3.p
xx4.p
asdfxx.p

Code:

#!/usr/bin/perl -w
$test = "xx1.p  xx2.r \n (xx3.p) ( xx4.p ) \n xx5.r xx.p.pxx \n asdfxx.p \n xxixiadsf.xx.p  \n xx4.p {xx5.p}   (  xx6.p)";
while ($test =~ /(xx.*\.p)/g) {
       print "$1\n";
}

Output

Code:

xx1.p
xx3.p) ( xx4.p
xx5.r xx.p.p
xx.p
xxixiadsf.xx.p
xx4.p {xx5.p}   (  xx6.p

Any help would be appreciated.
Thank you,
Cammy
