NAME
uniq - report or omit repeated lines SYNOPSIS
uniq [OPTION]... [INPUT [OUTPUT]] DESCRIPTION
Discard all but one of successive identical lines from INPUT (or standard input), writing to OUTPUT (or standard output). Mandatory arguments to long options are mandatory for short options too. -c, --count prefix lines by the number of occurrences -d, --repeated only print duplicate lines -D, --all-repeated[=delimit-method] print all duplicate lines delimit-method={none(default),prepend,separate} Delimiting is done with blank lines. -f, --skip-fields=N avoid comparing the first N fields -i, --ignore-case ignore differences in case when comparing -s, --skip-chars=N avoid comparing the first N characters -u, --unique only print unique lines -z, --zero-terminated end lines with 0 byte, not newline -w, --check-chars=N compare no more than N characters in lines --help display this help and exit --version output version information and exit A field is a run of blanks (usually spaces and/or TABs), then non-blank characters. Fields are skipped before chars. Note: 'uniq' does not detect repeated lines unless they are adjacent. You may want to sort the input first, or use `sort -u' without `uniq'. AUTHOR
