Extract the last directory of a pwd output

How do I extract the last directory of a pwd output? I don't want to use any knowledge of how many levels there are in the directory structure. If I wanted to use that, I could do something like:

> pwd
/home/kiki/dev/my_project
> pwd | cut -d'开发者_如何学编程/' -f5
my_project

But I want to use a command that works regardless of where I am in the directory structure. I assume there is a simple command to do this using awk or sed.

Are you looking for basename or dirname?

Something like

basename "`pwd`"

should be what you want to know.

If you insist on using sed, you could also use

pwd | sed 's#.*/##'

---

If you want to do it completely within a bash script without running any external binaries, ${PWD##*/} should work.

---

Using awk:

pwd | awk -F/ '{print $NF}'

---

Should work for you: pwd | rev | cut -f1 -d'/' - | rev
