How to set 4 space tab in bash

Question

It look like set tabstop=4 in VIM, but I don\'t know how to set it in bash

for example:

echo -e \"1234567890\\t321\\n1\\t2\         


        

Answer 1

tabs 4 results in the following tabstop positions. Which isn't quite what you asked for.

tab stop positions 4,8,12,16,20,24,28,32,36,40,44,48,52,56,60,64,68,72,76,80
         1         2         3         4         5         6         7         8

You asked for this..

tab stop positions 5,9,13,17,21,25,29,33,37,41,45,49,53,57,61,65,69,73,77,80
         1         2         3         4         5         6         7         8
12345678901234567890123456789012345678901234567890123456789012345678901234567890

Specifying tabs with a single number creates an implicit list that starts from 0.
To create an explicit list such as what you asked for. Provide a comma or space separated list of tab stop positions.
Like so: tabs 5,9,13,17,21,25,29,33,37,41,45,49,53,57,61,65,69,73,77

See man tabs and tabs -v for more details.
