+ Like clear(1), tabs writes to the standard output. You can redirect
+ the standard output to a file (which prevents tabs from actually chang-
+ ing the tabstops), and later cat the file to the screen, setting tab-
+ stops at that point.
-
-Tname
- Tell tabs which terminal type to use. If this option
- is not given, tabs will use the $TERM environment
- variable. If that is not set, it will use the
- ansi+tabs entry.
-
- -d The debugging option shows a ruler line, followed by
- two data lines. The first data line shows the
- expected tab-stops marked with asterisks. The second
- data line shows the actual tab-stops, marked with
- asterisks.
-
- -n This option tells tabs to check the options and run
- any debugging option, but not to modify the terminal
- settings.
-
- The tabs program processes a single list of tab stops.
- The last option to be processed which defines a list is
- the one that determines the list to be processed.
-
- ImplicitLists
- Use a single number as an option, e.g., "-5" to set tabs
- at the given interval (in this case 1, 6, 11, 16, 21,
- etc.). Tabs are repeated up to the right margin of the
- screen.
-
- ExplicitLists
- An explicit list can be defined after the options (this
- does not use a "-"). The values in the list must be in
- increasing numeric order, and greater than zero. They are
- separated by a comma or a blank, for example,
-
- tabs 1,6,11,16,21
- tabs 1 6 11 16 21
- Use a '+' to treat a number as an increment relative to
- the previous value, e.g.,
-
- tabs 1,+5,+5,+5,+5

which is equivalent to the 1,6,11,16,21 example.
- PredefinedTab-Stops
+
+
+ IEEE Std 1003.1/The Open Group Base Specifications Issue 7
+ (POSIX.1-2008) describes a tabs utility. However
- The -d (debug) and -n (no-op) options are extensions not
- provided by other implementations.
+ o This standard describes a +m option, to set a terminal's left-mar-
+ gin. Very few of the entries in the terminal database provide this
+ capability.
- Documentation for other implementations states that there
- is a limit on the number of tab stops. While some termi-
- nals may not accept an arbitrary number of tab stops, this
- implementation will attempt to set tab stops up to the
- right margin of the screen, if the given list happens to
- be that long.
+ o There is no counterpart in X/Open Curses Issue 7 for this utility,
+ unlike tput(1).
+ The -d (debug) and -n (no-op) options are extensions not provided by
+ other implementations.
