so if i use my your code in my example (my bash is version is 3.00.16)
Code:
#!/bin/bash
VAR="serial=1234"
[[ $VAR =~ ^[a-zA-Z]+?=[\.\/a-zA-Z0-9_-]+?$ ]] && printf '$VAR is ok: %s\n' "$VAR" || printf '$VAR is not ok: %s\n' "$VAR"
Did you notice that I changed the regex?
The Perl regular expressions are more powerful, in bash you don't have (and you don't need it in this case) the non-greedy operator ?.
You also don't need to escape the characters inside the character class.
Quote:
I get ...
Code:
# /tmp/test.sh
$VAR is not ok: serial=1234
can you see what im doing wrong here ?
m sure the regex is OK, because as you can see from my perl and egrep examples above, it all matches fine ?
Try modifying the regular expression as in my previous post.

Why is only hello3 being printed? There must be some kind of syntax problem because the file list definitely includes all the file extensions line by line.

Test::Email(3pm) User Contributed Perl Documentation Test::Email(3pm)NAME
Test::Email - Test Email Contents
SYNOPSIS
use Test::Email;
# is-a MIME::Entity
my $email = Test::Email->new(@lines);
# all-in-one test
$email->ok({
# optional search parameters
from => ($is or qr/$regex/),
subject => ($is or qr/$regex/),
body => ($is or qr/$regex/),
headername => ($is or qr/$regex/),
}, "passed tests");
# single-test header methods
$email->header_is($header_name, $value, "$header_name matches");
$email->header_ok($header_name, $value, "$header_name matches");
$email->header_like($header_name, qr/regex/, "$header_name matches");
# single-test body methods
$email->body_is($header_name, $value, "$header_name matches");
$email->body_ok($header_name, $value, "$header_name matches");
$email->body_like($header_name, qr/regex/, "$header_name matches");
# how many MIME parts does the messages contain?
$email->parts_ok($parts_count, "there were $parts_count parts found");
# what is the MIME type of the firs part
my @parts = $email->parts(); # see MIME::Entity
$parts[0]->mime_type_ok('test/html', 'the first part is type text/html');
DESCRIPTION
Please note that this is ALPHA CODE. As such, the interface is likely to change.
Test::Email is a subclass of MIME::Entity, with the above methods. If you want the messages fetched from a POP3 account, use Test::POP3.
Tests for equality remove trailing newlines from strings before testing. This is because some mail messages have newlines appended to them
during the mailing process, which could cause unnecessary confusion.
This module should be 100% self-explanatory. If not, then please look at Test::Simple and Test::More for clarification.
METHODS
"my $email = Test::Email->new($lines_aref);"
This is identical to "MIME::Entity->new()". See there for details.
"$email->ok($test_href, $description);"
Using this method, you can test multiple qualities of an email message with one test. This will execute the tests as expected and will
produce output just like "Test::Simple::ok" and "Test::More::ok". Keys for $test_href are either "body", or they are considered to be
the name of a header, case-insensitive.
single-test methods
The single-test methods in the synopsis above are very similar to their counterparts in Test::Simple and Test::More. Please consult
those modules for documentation.
Please note that tests for equality remove newlines from their operands before testing. This is because some email messages have
newlines appended to them during mailing.
"my $ok = $email-"parts_ok($parts_count, $description);>
Check to see how many MIME parts this email contains. Each part is also a Test::Email object.
"my $ok = $email-"mime_type_ok($expected_mime_type, $description);>
Check the MIME type of an email or an email part.
EXPORT
None.
