convert tabs to spaces, the easy way

Lots of times you want to convert tabs to spaces and sometimes from a shell script, if that is the case, then simple solution is “tidy“. First you need to install tidy as follows:

sudo yum install tidy

and then you can use the command tab2space.

tab2spcae

This will print the output to STDOUT by default which you can redirect if you want.
