tabs sends a series of characters to the standard output, designed to clear the
terminal hardware’s tab stops and then set new ones. The characters that are sent
depend on the type of terminal you are using.
The first column of your terminal screen is column 1. If you set a tab stop at
position N and then tab to that position, the next character displayed on the screen
appears in column N+1 of the line (that is, after the tab stop).
tabs may not be able to set the tab stops on some types of terminals. In this
situation, it issues an error message and then exits with a status greater than zero.
tabs with no arguments sets tab stops every 8 positions.
+m[margin]
Sets the left margin to margin. It defaults to 10 if you do not specify a
value. All tab positions are relative to the left margin. To find the actual tab
positions, you add the value of margin to each tab position.
–T type
Indicates the type of terminal you have. The term argument is a site-specific
name for your terminal type.
If you do not specify –T, tabs looks for an environment variable named
TERM and uses its value for type. If TERM is not defined, tabs assumes a
default terminal type.
–t tablist
Sets tab stops as specified by tablist. tablist consists of one or more
positive decimal integers, separated by commas; the numbers in the list
should be in strictly increasing order.
If only one number N is given, tabs are set every N columns. If more than
one number is given, tabs are set at those column numbers.
num1[,num2,...]
Sets tab stops to the given numbers. The numbers in the list should be
positive decimal integers in strictly increasing order. Except for the first
number, any number in the list may be preceded by a plus sign (+), in
