SRF (SORT_FILE) -- Sort and/or merge text files.
usage: SRF [-B | -S n] [-D | -I] [-F | -M | -R]... [pathname]...
FORMAT
SRF [options] [pathname ...]
SRF sorts lines of all the named files together and writes the result on the
standard output.
The sort key is an entire line. Default ordering is alphabetic by characters
as they are represented in ASCII format (digits, then uppercase characters,
then lowercase characters, then special characters).
ARGUMENTS
pathname
(optional) Specify file(s) to be sorted. Multiple pathnames are
permitted.
Default if omitted: read standard input
OPTIONS
Sort Key Control: one of the following
-B Omit leading blanks from keys.
-S n Sort based on the subfield starting in column n. If this
option is omitted, sorting starts in column one.
-F Fold all letters to a single case.
Input Character Control: either of the following
-D Use 'dictionary' order: only letters, digits and blanks are
significant in comparisons. Special characters
(punctuation, control characters, etc.) are ignored.
-I Ignore all nonprinting, nonblank characters.
Sort Mode Control: one of the following
-M Merge only, the input files are already sorted.
-R Reverse the sense of the sort; list output entries in
reverse order.
