Filter filenames by pattern

Question

I need to search for files in a directory that begin with a particular pattern, say "abc". I also need to eliminate all the files in the result that end with ".xh". I am not sure how to go about doing it in Perl.

I have something like this:

opendir(MYDIR, $newpath);
my @files = grep(/abc\*.*/,readdir(MYDIR)); # DOES NOT WORK

I also need to eliminate all files from result that end with ".xh"

Thanks, Bi

Answer 1

try

@files = grep {!/\.xh$/} <$MYDIR/abc*>;

where MYDIR is a string containing the path of your directory.

Answer 2

opendir(MYDIR, $newpath); my @files = grep(/abc*.*/,readdir(MYDIR)); #DOES NOT WORK

You are confusing a regex pattern with a glob pattern.

#!/usr/bin/perl

use strict;
use warnings;

opendir my $dir_h, '.'
    or die "Cannot open directory: $!";

my @files = grep { /abc/ and not /\.xh$/ } readdir $dir_h;

closedir $dir_h;

print "$_\n" for @files;

Answer 3

opendir(MYDIR, $newpath) or die "$!";
my @files = grep{ !/\.xh$/ && /abc/ } readdir(MYDIR);
close MYDIR;
foreach (@files) { 
   do something
}
