String found where operator expected at 2.pl line 2, near "lne '$i++ if /^+ /}{print $i'"
(Do you need to predeclare lne?)
Number found where operator expected at 2.pl line 2, near "'$i++ if /^+ /}{print $i' 1"
(Missing operator before 1?)
syntax error at 2.pl line 2, near "lne '$i++ if /^+ /}{print $i'"
Execution of 2.pl aborted due to compilation errors.

It's not a script meant to be saved to a file - it's a "one-liner", meaning a command that you enter on the command line (aka in your shell). That's the same place you would normally enter, for example, perl scriptfilename.pl
