.SH DESCRIPTION
|
|
|
|
|
.PP
|
|
|
|
|
.I Sort
|
|
|
|
|
sorts one or more files.
|
|
|
|
|
If no files are specified, \fIstdin\fR is sorted.
|
|
|
|
|
Output is written on standard output, unless \fB\-o\fP is specified.
|
|
|
|
|
The options \fB+\fIpos1 \fB\-\fIpos2\fR use only fields \fIpos1\fR
|
|
|
|
|
up to but not including \fIpos2\fR as the sort key, where a field is a
|
|
|
|
|
string of characters delimited by spaces and tabs, unless a different field
|
|
|
|
|
delimiter is specified with \fB\-t\fR.
|
|
|
|
|
Both \fIpos1\fR and \fIpos2\fR have the form \fIm.n\fR where \fIm\fR tells
|
|
|
|
|
the number of fields and \fIn\fR tells the number of characters.
|
|
|
|
|
Either \fIm\fR or \fIn\fR may be omitted.
