Extract directory path and filename

Question

I have a variable which has the directory path, along with the file name. I want to extract the filename alone from the Unix directory path and store it in a variable.

Answer 1

Use the basename command to extract the filename from the path:

[/tmp]$ export fspec=/exp/home1/abc.txt 
[/tmp]$ fname=`basename $fspec`
[/tmp]$ echo $fname
abc.txt
