I probably know lots of tips and tricks about using
/bin/sh that are not widely enough known about.
Today’s shell tip:
It’s a shell pattern that expands to all the sub-directories of the current directory.
If you want to list all the names of the sub-directories in the current directory it’s a lot easier to type
echo */. than it is to type
find . -name . -o -type d -print -prune which is almost equivalent.
ls -ld */.
