# sbostuff.sh

# bash functions for sbostuff. And I do mean *bash*: I don't know a
# completely portable way to write this stuff, and I don't use other
# shells. Patches accepted, if you're really motivated to make this
# work in your favorite shell.

# Source this file from your ~/.bashrc or similar:
# source /path/to/sbostuff/functions.sh
# ...or place this file in /etc/profile.d/ with +x permission.

visl - edit the .SlackBuild, .info, README, and slack-desc in the

Usage: visl <opts>

The editor used is controlled by environment variables. If VISUAL
is set, it's used as the editor. Otherwise, if EDITOR is set, it's
used. If neither are set, the default is "vim".

If given, <opts> are passed to the editor as options.

Usage: cdsb <build>

With no <build> argument, changes to the root of the SBo tree.

partial name, which will be matched case-insensitively.
