In the<br /> normal case, the second and succeeding copies of repeated<br /> lines are removed; the remainder is written on the output<br /> file. Note that repeated lines must be adjacent in order to<br /> be found; see _s_o_r_t(1). If the -u flag is used, just the<br /> lines that are not repeated in the original file are output.<br /> The -d option specifies that one copy of just the repeated<br /> lines is to be written. The normal mode output is the union<br /> of the -u and -d mode outputs.<br /> <br /> The -c option supersedes -u and -d and generates an output<br /> report in default style but with each line preceded by a<br /> count of the number of times it occurred.<br /> <br /> The _n arguments specify skipping an initial portion of each<br /> line in the comparison:<br /> <br /> -_n The first _n fields together with any blanks before<br /> each are ignored. A field is defined as a string of<br /> non-space, non-tab characters separated by tabs and<br /> spaces from its neighbors.<br /> <br /> +_n The first _n characters are ignored. Fields are<br /> skipped before characters.<br /> <br /> == SEE ALSO ==<br /> [[32v 1m sort|sort(1)]], [[32v 1m comm|comm(1)]]<br /> <br /> [[Category:32v man section 1]]</div>
