The first of these does not work for me (at least on perl 5.005_03) The second is cunning enough though. `perl -lpe 'substr $_, 0, 1 = "";' Can't modify constant item in scalar assignment at -e line 1, near """ +;" Execution of -e aborted due to compilation errors. perl -lpe 'substr $_, 0, 1, "";' this is his is` [download] The first one will work with a minor tweak `perl -lpe 'substr($_, 0, 1) = "" ' test est` [download] Cheers, R.

Execution of -e aborted due to compilation errors.
