=head1 DESCRIPTION |
53
|
|
|
|
|
|
|
|
54
|
|
|
|
|
|
|
This filter rule removes extra slashes (e.g. "/foo//bar" becomes "/foo/bar") and |
55
|
|
|
|
|
|
|
trailing slash. |
56
|
|
|
|
|
|
|
|
57
|
|
|
|
|
|
|
Regarding trailing slash: functions might not expect a filename or dirname to |
58
|
|
|
|
|
|
|
have a trailing slash (e.g. C<-d>, C<opendir()>, etc will not work if we add |
59
|
|
|
|
|
|
|
slash to a directory name), but shell tab completion usually adds a trailing |
60
|
|
|
|
|
|
|
slash. So this filter rule provides the convenience of stripping the trailing |
61
|
|
|
|
|
|
|
slash for the functions. |
