Identifying words containing a specific substring in a sentence (was: a simple question)
Tip: This is a beginners list, therefore many questions will be simple.
Aim for more descriptive subject lines and life will be easier for
users of the list archives.

For the following string:

What is the command to extract the substrings with "xyz" in them? In
this case, I'd like to get two strings "axyzb" and "cxyzd".
The useful functions here are "grep" and "split" (perdoc -f grep and so
on).
#!/usr/bin/perl
use strict;
use warnings;
my $string = " axyzb cxyzd ";
my @list_of_words = split /\ /, $string;
my @list_of_words_containing_xyz = grep /xyz/, @list_of_words;
foreach my $word (@list_of_words_containing_xyz) {
print $word, "\n";
}
or, in less verbose form:
foreach (grep(/xyz/,split(/\ /, " axyzb cxyzd "))) { print
$_, "\n"; }
