Nothing, as far as I can tell. I believe it is your point of view what
PATH_DIRS is doing. As long as "somescript" is in your PATH,
I don't believe PATH_DIRS is doing much if anything.
Try the following to understand what PATH_DIRS can do:
mv ../System/somescript ../System/Subdir
. Subdir/somescript # script should not run
. Subdir/somescript # should see output from script
I believe from reading the man page, this is what PATH_DIRS is
intended to do. As Bart said, it *uses* PATH. If you +x somescript
you can just type:
At least this is how I interpreted what PATH_DIRS, as defined in the man
page, does. "Perform a path search even on command names with
slashes in them." Maybe it should say, "In addition to the normal path
search, preform a path search on command names with slashes in them."
Maybe I'm missing some other case use.
Hope this helps.
