Question

I would like my bash script to check the name of the directory where it is run. Something like:

#!/bin/bash

path=eval 'pwd'

dirname=eval 'basename $path'

But it doesn’t work: I get

./foo.sh: line 5: basename $path: command not found

How can I fix it? Also, once I get dirname to contain the correct dirname, I’d like to convert it to lowercase, to test it. I’m able to do this on the command line with awk:

echo $dirname | awk '{print tolower($0)}'

but how do I capture the return value into a variable?

Why not use:

#!/bin/bash

path=`pwd`
dirname=`basename $path | awk '{print tolower($0)}'`

Or if you want to do it as a one liner:

dirname=`pwd | xargs basename | awk '{print tolower($0)}'`
