- sorts one or more files.
- If no files are specified, fIstdinfR is sorted.
- Output is written on standard output, unless fB-ofP is specified.
- The options fB+fIpos1 fB-fIpos2fR use only fields fIpos1fR
- up to but not including fIpos2fR 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-tfR.
- Both fIpos1fR and fIpos2fR have the form fIm.nfR where fImfR tells
- the number of fields and fInfR tells the number of characters.
- Either fImfR or fInfR may be omitted.
