[Help-bash] Is there a way to combine $( and ${%}?

[Peng Yu]

Hi,

I have the following commands. Is there a way to combine them into one command?

x=$(readlink -e "$0")
x=${x%/*}

There you go. Now it's one command.

​Works. But if the OP wants another technically correct, but worse, answer,
there is always:

x=$(readlink -e "$0" | sed -r 's|^(.*)/[^/]*$|\1|' )​

Gotta love seeing one nonportable command with a raising with a second
nonportable command.

Also, as long as I'm in this thread:
