# stale-symlink-buildworld.sh - check for stale symlinks on a FreeBSD system
|
|
#
|

# The purpose of this script is to detect stale symlinks, report them to
|
|
# stderr and exit with a non-zero status. All other cases are ignored,
|
|
# such as no symlinks, missing directories, permission problems, etc.
|
|
#
|
|
# You can run the script before or after `make installworld', or any other
|
|
# make targets thats installs files.
|
|
#
|
|
# You can also check your local ports with:
|
|
#
|
|
# env STALE_SYMLINK_BUILDWORLD_DIRS=/usr/local ./stale-symlink-buildworld.sh
