Uniq examines a file for consecutive lines that are identical. All but
|
|
duplicate entries are deleted, and the file is written to output. The +n
|
|
option skips the first n fields, where a field is defined as a run of
|
|
characters separated by white space. The -n option skips the first n
|
|
spaces. Fields are skipped first.
