Re: Regex to remove data

Something like this should do the trick:

#! perl
use strict;
use warnings;

my @lines = <DATA>;

s/ ^ [A-Z\s]+ $ //x for @lines;

print for @lines;

__DATA__
AAAAAAAA
AAAA AAAAAAA
AAAA AAA AAA
Leave me intact PLEASE
[download]

Output:

 0:10 >perl 369_SoPW.pl
Leave me intact PLEASE

 0:13 >
[download]

Update 1: Note that this will also remove blank (i.e. empty) lines.

Update 2: Changed

print "@lines";
[download]

print for @lines;
[download]

to address the issue of leading spaces raised by Anonymous Monk, below.

Hope that helps,

This is good, but the OP did say he wanted to remove the lines from a "large file", but your approach reads the entire file into an in-memory array (`@lines`) and processes that. Check out my reply below for an example that loads only one line into memory at a time (the `-n` switch assumes `while (<>)`).	[reply] [d/l] [select]

Thanks,though it adds a leading space to each line	[reply]
