SORT−UNIQ−COUNT

NAME

sort−uniq−count, sort−uniq−count−rank − print line frequencies

SYNOPSIS

sort−uniq−count[−rank] [[]b] [[]f] [[]i] [[]n] [[]r] [[]s]

DESCRIPTION

sort−uniq−count and sort−uniq−count−rank each read a text file on standard input, sort it according to any specified flags (-f by default), and report to standard output how often each input line occurs. Each output line consists of a count followed by a tab and an input line.

sort−uniq−count produces its output in the user’s choice of sort order. sort−uniq−count−rank sorts its output primarily from highest to lowest count, with the user’s sort order as a tiebreaker.

[]f

Ignore capitalization.

[]i
