vim has a really nice feature which it utilizes in its paths when they’re a bit long:
It abbreviates the path to the document in the tab at the top. Is there a way to do something similar to this so my bash prompt doesn’t look like this:
<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a8dacec3dac7cbc3dcc3e8dfc7dac385c4c9d8dcc7d8">[email protected]</a> ~/Documents/Projects/Work/maventest/src/main/java/com/tkassembled/ $

Method 1
I like PROMPT_DIRTRIM in bash…
export PROMPT_DIRTRIM=2
will change your example prompt to…
<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bfcdd9d4cdd0dcd4cbd4ffc8d0cdd492d3decfcbd0cf">[email protected]</a> ../com/tkassembled/ $
It works for me.
Method 2
Try this:
PROMPT_COMMAND='PS1X=$(perl -pl0 -e "s|^${HOME}|~|;s|([^/])[^/]*/|$""1/|g" <<<${PWD})'
or, pure bash:
PROMPT_COMMAND='PS1X=$(p="${PWD#${HOME}}"; [ "${PWD}" != "${p}" ] && printf "~";IFS=/; for q in ${p:1}; do printf /${q:0:1}; done; printf "${q:1}")'
then
PS1='<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="374277">[email protected]</a>h ${PS1X} $ '
produces (notice the ~ for ${HOME}):
<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1664707d6479757d627d566179647d3b7a7766627966">[email protected]</a> ~/D/P/W/m/s/m/j/c/tkassembled $
I improved my answer thanks to @enzotib’s
Method 3
Similar to @nicerobot answer, but somewhat shorter:
PROMPT_COMMAND='pwd2=$(sed "s:([^/])[^/]*/:1/:g" <<<$PWD)' PS1='<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="592c19">[email protected]</a>h:$pwd2$ '
This will show the followin example output:
<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="35505b4f5a415c577554565047">[email protected]</a>:/h/enzotib$ cd <a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="c7a2a9bda8b3aea587a6a4a2b5">[email protected]</a>:/h/enzotib$ cd /usr/share/doc/acpid/examples/ <a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="e3868d998c978a81a382808691">[email protected]</a>:/u/s/d/a/examples$
Method 4
Adding on to enzotib‘s answer, the following snippet will:
- Convert
/Path/To/Your/Home/to~/(so a path will be~/a/b/cinstead of/P/T/Y/H/a/b/c) -
Use the first letter of a ‘dot file’ instead of showing only the dot (
/a/./c/dwill become/a/.b/c/d):PROMPT_COMMAND='PS1_PATH=$(sed "s:([^/.])[^/]*/:1/:g" <<< ${PWD/#$HOME/~})' export PS1='<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="6b1e2b">[email protected]</a>h:$PS1_PATH$ '
Make sure you use single quotes or bash will expand it prematurely.
Method 5
The format for use in your PS1 is W (see the PROMPTING section in the bash man page).
PS1="<a href="https://getridbug.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="e396a3">[email protected]</a>h W$ "
And you might want to read the other options there, you can do some cool stuff with your command line.
Method 6
I love the output from nicerobot’s example but I found one issue. I have a directory that has a hyphen in it, A-E, and it was seeing -E as an argument to printf when it was my current working directory. To fix this, I added -- to the last printf and added quotes around the output in case there is nothing to output:
p="${PWD#${HOME}}"; [ "${PWD}" != "${p}" ] && printf "~";IFS=/; for q in ${p:1}; do printf /${q:0:1}; done; printf -- "${q:1}"
