Backspace characters are preserved. By default, unexpand compresses only
leading spaces into tabs; tab stops are set every eight spaces.
unexpand supports the following options:
–a Compresses spaces into tabs wherever the resulting output is shorter,
regardless of where the spaces occur in the line.
–t tablist
Specifies tab stops. The numbers in tablist are delimited by blanks or
commas. If tablist is a single number, then unexpand places tab stops
every tablist positions. If tablist contains multiple numbers, unexpand
places tab stops at those specific positions. Multiple numbers in tablist must
be in ascending order. This option, like the –a option, compresses spaces
to tabs at any appropriate point in the line. If you specify –t, unexpand
ignores the presence or absence of –a.
unexpand uses the following localization variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES
v NLSPATH
See Appendix F for more information.

uniq — Report or filter out repeated lines in a file
Format
Description
uniq [–c|–d|–u] [–f number1] [–s number2] [input_file [output_file]]
uniq [–cdu] [–number] [+number] [input_file [output_file]]
uniq manipulates lines that occur more than once in a file. The file must be sorted,
since uniq only compares adjacent lines. When you invoke this command with no
options, it writes only one copy of each line in input_file to output_file. If you do not
specify input_file or you specify –, uniq reads the standard input.
