SYNOPSIS
       unexpand [OPTION]... [FILE]...

DESCRIPTION
       Convert blanks in each FILE to tabs, writing to standard output.

       With no FILE, or when FILE is -, read standard input.

       Mandatory  arguments  to  long  options  are  mandatory  for short
       options too.

       -a, --all
              convert all blanks, instead of just initial blanks

              convert only leading sequences of blanks (overrides -a)

              have tabs N characters apart instead of 8 (enables -a)

       -t, --tabs=LIST
              use comma separated list of tab positions The  last  speci‐
              fied  position  can  be  prefixed with '/' to specify a tab
              size to use after the last explicitly specified  tab  stop.
              Also  a  prefix  of  '+' can be used to align remaining tab
              stops relative to the last specified tab  stop  instead  of
              the first column
