How to change tab from 8 to 4 spaces

when i press tab in terminal it auto completes. are you in some kind of text editor like vi, nano, emacs?

auto complete works fine. When I print a file using "more" the tabs are set at 8 spaces. I would like the default to be 4 spaces instead.

I don't know about any option in more for tabs but you could use less in stead of more (less is better than more)

man less says :

       -xn,... or --tabs=n,...
              Sets tab stops. If only one n is specified, tab stops are set
              at multiples of n. If multiple values separated by commas are
              specified, tab stops are set at those positions, and then con‐
              tinue with the same spacing as the last two. For example,
              -x9,17 will set tabs at positions 9, 17, 25, 33, etc. The
              default for n is 8.

Thanks. Maybe I can find that setting on all the apps I use.

The holy grail I was looking for was to change a system setting that would cause all of the apps to use a 4 space tab instead of an 8 space. That would include vim, less, more, cat, etc... This is a 4 space house not 8. ;-)

But if it doesn't exist I can live with it.

hehe thats funny. its true but its funny.

I have just started learning python and there TABs are used for displaying blocks.. I really dont like the default TAB size of 8.. 4 is enough for me. Please tell me if there is a way. There must be something. Linux is customizable, so there should be a way.
