tabs [tabspec] [options]Set terminal tab stops according to tabspec. The default tabspec, -8, gives the standard Unix tab settings. Specify tabspec as a predefined set of tab stops for particular languages, for example: a (IBM assembler), c (COBOL), f (FORTRAN), p (PL/1), s (SNOBOL), and u (UNIVAC assembler). tabspec can also be a repeated number, arbitrary numbers, or called from a file.
-nRepeat tab every n columns (e.g., 1+n, 1+2*n, etc.).
Arbitrary ascending values. If n is preceded by +, it is added (i.e., tab is relative to previous position).
