Removing programs

In GoboLinux, all programs, whether binary packages or user-compiled software, are installed into a single directory under the /Programs hierarchy, such as, for instance, gimp:

    /Programs/Gimp/2.8.18

Removing this program can be, in theory, as simple as:

    rm -rf Gimp/2.8.18 

But since this leaves behind dangling symlinks, GoboLinux offers the RemoveProgram utility, which removes the program and all links pointing to its files in /System/Index.

    RemoveProgram Gimp 2.8.18

Sometimes you may want to "turn off" a program temporarily, without erasing it from your hard disk. In other words, you want to remove program's executables from the execution path, and remove libraries and headers from the lookup path.

In GoboLinux, this can be accomplished by removing the associated symlinks for /System/Index. The DisableProgram script facilitates this:

    DisableProgram gimp 2.1.18

The version parameter given here, in this case 2.1.18, is optional. If it is not provided, the "Current" link is used to determine the program version to disable. Also note that the program name is case insensitive, but it appears to be simpler to use a downcased variant - easier to type at the least.

To re-enable the program, all you need to do is recreate the symbolic links:

    SymlinkProgram gimp 2.1.18

Maintaining symlinks

GoboLinux has a script called RemoveBroken. that removes dangling symlinks from /System/Index tree. It can be useful to run after manipulating directories under /Programs.

RemoveBroken takes a list of files, and removes those that are dangling symlinks. If no arguments are provided, the script takes filenames from standard input (typically through a pipe).

The usual procedure to clean up dangling links, is

    cd /System/Index
    find | RemoveBroken
