Subject: quick and dirty test for empty directory
Date: Wed, 16 Nov 2022 08:17:38 -0800 [thread overview]
Message-ID: <620799bc-8224-7cf3-b1c5-2ae5467f0a98@eastlink.ca> (raw)
Best advice googling for such a test is this:
[ -d "$dir" ] && [ -n "$(ls -A $dir)" ] # If true,
dir isn't empty.
... but experimenting:
2 /media/sdb 0 $ [ /media/sdb/3/* ] && echo file found
2 /media/sdb 0 $ [ /media/sdb/2/* ] && echo file found
file found
... correct result. I does have a certain logic to it. If there's no
expansion then the test fails. Dare I use it or is this bound to crash
and burn somehow or other? Anyway I can't believe a call to 'ls' is
really needed.
