Determine string in Perl.
Hi,
I have a little Perl question.
I need to determine the last word in the following string:
h t t p://abc.def.com/hijklm
The output should be the string hijklm.
h t t p is of course http.
The string between the slashes always differs.
The string after the last slash always differs.
Any idea how to do this ?
Best regards,
ejdv

I know how to ping in Perl. That is easy. What I am wondering is if there is a way for Perl to determine whether the ping was successful or not. Or do I need to save the results out and parse the results seperately looking for the #of tries and successful revieves.
Thanks. (1 Reply)

Trying to find out how to discover if the first 2 characters of a string are "22"
Not sure how.
I could use
if ]; then echo "yes";fi
But I think that will only grab the pattern 22 and not the first 2 digits. (5 Replies)

perl::critic::policy::builtinfunctions::prohibitstringysplit
Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySUser(Contributed Perl DocumPerl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit(3)
NAME
Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit - Write "split /-/, $string" instead of "split '-', $string".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The "split" function always interprets the PATTERN argument as a regular expression, even if you specify it as a string. This causes much
confusion if the string contains regex metacharacters. So for clarity, always express the PATTERN argument as a regex.
$string = 'Fred|Barney';
@names = split '|', $string; #not ok, is ('F', 'r', 'e', 'd', '|', 'B', 'a' ...)
@names = split m/[|]/, $string; #ok, is ('Fred', Barney')
When the PATTERN is a single space the "split" function has special behavior, so Perl::Critic forgives that usage. See "perldoc -f split"
for more information.
CONFIGURATION
This Policy is not configurable except for the standard options.
