=head1 NAME
|
|
|
|
fix-perl-path.PL - A script to correct the shebang line to match the current platform
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
=head2 BASIC USAGE
|
|
|
|
perl fix-perl-path.PL /absolute/path/to/foo
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This script should be run from the base of the directory
|
|
structure which contains the file(s) that need the
|
|
shebang line corrected. It will recurse through all
|
|
directories below the one called from and modify all
|
|
.pl files.
|
|
|
|
=head2 fixshebang
|
|
|
|
This sub will recurse through a given directory and its subdirectories checking for the existence of a shebang
|
|
line in .pl files and replacing it with the correct line for the current OS if needed. It should be called
|
|
in a manner similar to 'fixshebang (foodir)' but may be supplied with any directory.
