This may be poorly titled as I'm not fully sure what the process is called. Basically I want to get only the last part of a symlink path, and I'm trying to use the same method I use with PWD.
For example: if I do
PWD
it prints
/opt/ct/mydir
if I do
echo ${PWD##*/}
it prints only the last part
mydir
So using that design I can do
readlink mysymlink
which gives
/opt/ct/somedir
and I can do
TMP=$(readlink mysymlink)
echo ${TMP##*/}
and it will print
somedir
So now how can I combine that last part into one line like
TMP=$(readlink mysymlink && echo ${TMP##*/})
???
The example I show gives me 2 concatenated results.. one with the full path and one with just the part I want. I only want that last directory.
I also tried
TMP=${ $(readlink mysymlink)##*/}
to no avail
Variable substitution suffixes can only be used with variables, not command substitutions. You either have to set the variable and modify it in separate statements, as in your first attempt, or use additional command substitutions:
TMP=$(basename $(readlink))
