Hello Justino.
I think I understand. You want to check that a string starts with
'-key' and ends with '-5L'. You'll need a regular expression with
these ingredients:
^ - matches only at the start of a string
$ - matches only at the end of a string
. - matches any character
putting these together within a regular expression 'match'
operation:
m/^-key.*-5L$/
(the * lets the . match any number of characters)
You can test your string like this:
if ($string =~ m/^-key.*-5L$/) {
:
}
Hope this helps,
Rob
