NAME

- - sort – sort and/or merge files

SYNOPSIS
- -
- - sort [ −cmuMbdfinrwtx ] [ +pos1 [ −pos2 ] ... ] ... [ −k pos1 - [ ,pos2 ] ] ...

DESCRIPTION
- -
- - Sort sorts lines of all the files together and writes the result - on the standard output. If no input files are named, the standard - input is sorted. -
- - The default sort key is an entire line. Default ordering is lexicographic - by runes. The ordering is affected globally by the following options, - one or more of which may appear.
- −M    Compare as months. The first three non-white space characters - of the field are folded to upper case and compared so that JAN - precedes FEB, etc. Invalid fields compare low to JAN.
- −b    Ignore leading white space (spaces and tabs) in field comparisons.
- −d    ‘Phone directory’ order: only letters, accented letters, digits - and white space are significant in comparisons.
- −f    Fold lower case letters onto upper case. Accented characters - are folded to their non-accented upper case form.
- −i    Ignore characters outside the ASCII range 040-0176 in non-numeric - comparisons.
- −w    Like −i, but ignore only tabs and spaces.
- −n    An initial numeric string, consisting of optional white space, - optional plus or minus sign, and zero or more digits with optional - decimal point, is sorted by arithmetic value.
- −g    Numbers, like −n but with optional e-style exponents, are sorted - by value.
- −r    Reverse the sense of comparisons.
- −tx   ‘Tab character’ separating fields is x. -
- - The notation +pos1 −pos2 restricts a sort key to a field beginning - at pos1 and ending just before pos2. Pos1 and pos2 each have the - form m.n, optionally followed by one or more of the flags Mbdfginr, - where m tells a number of fields to skip from the beginning of - the line and n tells a number of characters to skip - further. If any flags are present they override all the global - ordering options for this key. A missing .n means .0; a missing - −pos2 means the end of the line. Under the −tx option, fields - are strings separated by x; otherwise fields are non-empty strings - separated by white space. White space before a field is part of - the field, except under option −b. A b flag may be attached independently - to pos1 and pos2. -
- - The notation −k pos1[,pos2] is how POSIX sort defines fields: - pos1 and pos2 have the same format but different meanings. The - value of m is origin 1 instead of origin 0 and a missing .n in - pos2 is the end of the field. -
- - When there are multiple sort keys, later keys are compared only - after all earlier keys compare equal. Lines that otherwise compare - equal are ordered with all bytes significant. -
- - These option arguments are also understood:
- −c       Check that the single input file is sorted according to the - ordering rules; give no output unless the file is out of sort.
- −m       Merge; assume the input files are already sorted.
- −u       Suppress all but one in each set of equal lines. Ignored bytes - and bytes outside keys do not participate in this comparison.
- −o       The next argument is the name of an output file to use instead - of the standard output. This file may be the same as one of the - inputs.
- −Tdir     Put temporary files in dir rather than in /var/tmp.

EXAMPLES
- -
- - sort −u +0f +0 list - -
- - Print in alphabetical order all the unique spellings in a list - of words where capitalized words differ from uncapitalized.
- -
- sort −t: +1 /adm/users - -
- - Print the users file sorted by user name (the second colon-separated - field).
- -
- sort −umM dates - -
- - Print the first instance of each month in an already sorted file. - Options −um with just one input file make the choice of a unique - representative from a set of equal lines predictable.
- -
- grep −n '^' input | sort −t: +1f +0n | sed 's/[0−9]*://' - -
- - A stable sort: input lines that compare equal will come out in - their original order.

DIAGNOSTICS
- -
- - Sort comments and exits with non-null status for various trouble - conditions and for disorder discovered under option −c.
- -
-

BUGS
- -
- - An external null character can be confused with an internally - generated end-of-field character. The result can make a sub-field - not sort less than a longer field. -
- - Some of the options, e.g. −i and −M, are hopelessly provincial.
