NAME

SYNOPSIS

DESCRIPTION

In the first synopsis form, the tab stops set depend on the command line options used, and may be one of the predefined formats or at regular intervals.

In the second synopsis form, tab stops are set at positions n1, n2, etc. If a position is preceded by a ‘+’, it is relative to the previous position set. No more than 20 positions may be specified.

If no tab stops are specified, the “standard” UNIX tab width of 8 is used.

The options are as follows:

-n

Set a tab stop every n columns. If n is 0, the tab stops are cleared but no new ones are set.

-a

Assembler format (columns 1, 10, 16, 36, 72).

-a2

Assembler format (columns 1, 10, 16, 40, 72).

-c

COBOL normal format (columns 1, 8, 12, 16, 20, 55)

-c2

COBOL compact format (columns 1, 6, 10, 14, 49)

-c3

COBOL compact format (columns 1, 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50, 54, 58, 62, 67).

-f

FORTRAN format (columns 1, 7, 11, 15, 19, 23).

-p

PL/1 format (columns 1, 5, 9, 13, 17, 21, 25, 29, 33, 37, 41, 45, 49, 53, 57, 61).

-s

SNOBOL format (columns 1, 10, 55).

-u

Assembler format (columns 1, 12, 20, 44).

+m[n], +[n]

Set an n character left margin, or 10 if n is omitted.

-T type

ENVIRONMENT

The -T option overrides the setting of the TERM environment variable. If neither TERM nor the -T option are present, tabs will fail.
