/usr/bin/uniq --help
DESCRIPTION
uniq reads an input, comparing adjacent lines, and writing one copy of
each input line on the output. The second and succeeding copies of the
repeated adjacent lines are not written.
If the output file, output_file, is not specified, uniq writes to stan‐
dard output. If no input_file is given, or if the input_file is -, uniq
reads from standard input with the start of the file is defined as the
current offset.
OPTIONS
The following options are supported:
-c, --count
Precedes each output line with a count of the number of times the
line occurred in the input.
-d, --repeated
Suppresses the writing of lines that are not repeated in the input.
-D, --all-repeated[=delimit-method]
Delimit groups of duplicate lines using one of the following
delimit-methods:
none (default) No delimiting is done.
prepend Prepend each group with a delimiter.
separate Separate groups with a delimiter.
Delimiting is done with a blank line.
-f, -skip-fields=fields
Ignores the first fields fields on each input line when doing com‐
parisons, where fields is a positive decimal integer. A field is
the maximal string matched by the basic regular expression:
[[:blank:]]*[^[:blank:]]*
If fields specifies more fields than appear on an input line, a
null string is used for comparison.
-i, --ignore-case
Ignore differences in case when comparing.
-s, --skip-chars=chars
Ignores the first chars characters when doing comparisons, where
chars is a positive decimal integer. If specified in conjunction
with the -f option, the first chars characters after the first
fields fields are ignored. If chars specifies more characters than
remain on an input line, a null string is used for comparison.
-u, --unique
Suppresses the writing of lines that are repeated in the input.
-w, --check-chars=chars
Compare no more than chars characters in a line.
-z, --zero-terminated
End lines with 0 byte, not new line.
-n
Equivalent to -f fields with fields set to n.
+m
Equivalent to -s chars with chars set to m.
--help
Display command usage and exit.
OPERANDS
The following operands are supported:
input_file A path name of the input file. If input_file is not
specified, or if the input_file is −, the standard input
is used.
output_file A path name of the output file. If output_file is not
specified, the standard output is used. The results are
unspecified if the file named by output_file is the file
named by input_file.
EXAMPLES
Example 1 Using the uniq Command
The following example lists the contents of the uniq.test file and out‐
puts a copy of the repeated lines.
