To get only the last word of a commands output:

my ($variable) = `echo $line` =~ /(\w+)$/;

[download]

The parentheses around $variable enforce list context, which assigns the only pattern match of /(\w+)$/ (which is the last word of the command output) to $variable instead of just evaluating whether the string matches that pattern.

Had the parentheses been omitted, $variable would contain 1 if there were any words at the end of your commmands output and 0 otherwise.


If you want to actually remove the last word from a string, you can use regex substitution and capture the match:

my $output = `echo $line`;
$output =~ s/(\w+)$//;
my $last_word = $1;

The last word gets captured into the $1 variable replaced with an empty string (i.e. removed).
