I want to get a substring from a string based on given delimiter, for example:
with delimiter "|",
I want to get one substring at each time with the order number the substring in the whole string,
given 1 to get "foo",
given 2 to get "bar",
given 3 to get "baz",
I guess it could be done with sed and an regular expression, but I don't know how to write it.

Hi ,

echo abc 123 def 456 | sed 's|\(*\) \(*\)|\1|'

text::glob
Text::Glob(3) User Contributed Perl Documentation Text::Glob(3)NAME
Text::Glob - match globbing patterns against text
SYNOPSIS
use Text::Glob qw( match_glob glob_to_regex );
print "matched
" if match_glob( "foo.*", "foo.bar" );
# prints foo.bar and foo.baz
my $regex = glob_to_regex( "foo.*" );
for ( qw( foo.bar foo.baz foo bar ) ) {
print "matched: $_
" if /$regex/;
}
DESCRIPTION
Text::Glob implements glob(3) style matching that can be used to match against text, rather than fetching names from a filesystem. If you
want to do full file globbing use the File::Glob module instead.
Routines
match_glob( $glob, @things_to_test )
Returns the list of things which match the glob from the source list.
glob_to_regex( $glob )
Returns a compiled regex which is the equivalent of the globbing pattern.
glob_to_regex_string( $glob )
Returns a regex string which is the equivalent of the globbing pattern.
SYNTAX
The following metacharacters and rules are respected.
"*" - match zero or more characters
"a*" matches "a", "aa", "aaaa" and many many more.
"?" - match exactly one character
"a?" matches "aa", but not "a", or "aaa"
Character sets/ranges
"example.[ch]" matches "example.c" and "example.h"
"demo.[a-c]" matches "demo.a", "demo.b", and "demo.c"
alternation
"example.{foo,bar,baz}" matches "example.foo", "example.bar", and "example.baz"
leading . must be explictly matched
"*.foo" does not match ".bar.foo". For this you must either specify the leading . in the glob pattern (".*.foo"), or set
$Text::Glob::strict_leading_dot to a false value while compiling the regex.
"*" and "?" do not match /
"*.foo" does not match "bar/baz.foo". For this you must either explicitly match the / in the glob ("*/*.foo"), or set
$Text::Glob::strict_wildcard_slash to a false value with compiling the regex.
BUGS
The code uses qr// to produce compiled regexes, therefore this module requires perl version 5.005_03 or newer.
