A folder in Linux system. I want to loop through every .xls file in a folder.

This folder typically consists of various folders, various filetypes

Answer 1

Look at the find command.

What you are looking for is something like

find . -name "*.xls" -type f -exec program 

Post edit

find . -name "*.xls" -type f -exec xls2csv '{}' '{}'.csv;

will execute xls2csv file.xls file.xls.csv

Closer to what you want.
