Shorten very long dir name in bash prompt
How to get from this prompt
~/this/is/a-very-very-long-directory-name/dir
to this
~/this/is/a-ver...name/dir
in a bash prompt?
So shorten directory names longer than nn (20+) characters to something like xxxx...xxxx
note for possible duplicate: I want to shorten a long dir name, not a long path/to/dir

Hello @JuTutt. The possible duplicate also shortens a directory name, not a path. That being said, I think your question is more general than the linked one -- and also the answer is more complex (pre and post match). That's why I'm opposing the duplicate vote.

You'll need to use something like sed, bash doesn't have any builtin method.
d='~/this/is/a-very-very-long-directory-name/with_another_very_long_name/and-here-is-yet-another-one'
# or, d=$(pwd)
e=$( echo "$d" | sed -E 's#([^/]{4})[^/]{13,}([^/.]{3})#1...2#g' )
echo "$e"
~/this/is/a-ve...ame/with...ame/and-...one
On the other hand, you may want to throw a newline into your prompt. I use something like this:
PS1='u@h:wn$ '
which would look like
jackman@myhost:~/this/is/a-very-very-long-directory-name/with_another_very_long_name/and-here-is-yet-another-one

IFS=/
for DIR in $d

DIR=$TMP...${DIR##${DIR%????}}
}
NEW="$NEW${NEW:+/}$DIR"
done
echo "$NEW"
~/this/is/a-ve...name/with...name/and-...-one
Save and restore IFS if need be. Running in a subshell won't work as you want to access the NEW variable afterwards (unless you use "command substitution"...).

Hello @JuTutt. The possible duplicate also shortens a directory name, not a path. That being said, I think your question is more general than the linked one -- and also the answer is more complex (pre and post match). That's why I'm opposing the duplicate vote.
