Question Assigning the relative directory name to a variable called $DIR.
Hi All,

I've been trying to write a KSH script that acts on the name of the relative directory that this script is called from.

In other words, if I am executing this script from a directory called:
/hello/hithere/directory

How would I assign
DIR=

to be "directory" and not "/hello/hithere/directory" ?

Thank you so much !

Assuming that the full script name is in $spath (e.g. /usr2/bin/script), then the following code in Kshell will yield the last part of the directory:

Code:
fullpath=${spath%/*}     # full path of directory containing the command (removes script name)
dname=${fullpath##*/}  # strip all things from start to last / in the path

The result, given /usr2/bin/script, would be bin assigned to dname.

Perfect! Thank you!
In the case of Solaris, I was able to use the logic above to do it with:
Code:
DIR=${PWD##*/}

Thanks again!
