# sort-uniq-count(1)

print line frequencies

## 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.

## OPTIONS

- \[**-**\]**n**
