NAME

switch-link — retarget symlinks based on the extension of their targets

SYNOPSIS

DESCRIPTION

The switch-link utility examines all the symlinks in the current directory and its subdirectories, looking for those whose targets end in the .oldext extension as specified on the command line. If any of those are found, they are changed to point to a target with the same base name and a .newext extension as specified on the command line. This is useful in some setups when such symlinks are used to provide different images for different situations, e.g. holiday decoration.

Options:

-h

Display a usage message and exit.

-N

No-operation mode; just display what would have been done.

-V

Display program version information and exit.

-v

Verbose operation; display diagnostic messages.

RETURN VALUES

The switch-link utility exits 0 on success, and >0 if an error occurs.

ENVIRONMENT

The switch-link utility's operation is currently not directly affected by its environment.

FILES

The switch-link utility examines the current directory and all its subdirectories, and its operation is not further affected by any files.

EXAMPLES

Change all the symlinks pointing to *.nonch to point to the same file, but with a .ch extension:

TODO

*

Create a temporary file containing the list of links to avoid weird security-like issues or plain old incorrect operation resulting from whitespace in the link's name.
