=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. |
||||
