unexpand - convert spaces to tabs
unexpand [
OPTION]... [
FILE]...
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
- --first-only
- convert only leading sequences of blanks (overrides
-a)
-
-t, --tabs=N
- have tabs N characters apart instead of 8 (enables
-a)
-
-t, --tabs=LIST
- use comma separated list of tab positions. The last
specified 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
