MSORT(1) User Commands MSORT(1) NAME msort - sort records in complex ways SYNOPSIS msort <options> [<input file>] DESCRIPTION msort is a program for sorting text files in sophisticated ways. It was developed initially for alphabetizing dictionaries of languages in which the ordering may be quite different from English but has many other uses. msort allows you to sort blocks of text delimited in a number of ways rather than just lines and to specify particular fields of a record as sort keys using either their position, counted from either end, or by matching regular expressions to their tags. msort is capable of sorting on multiple keys, so that when two records tie on one key, the tie may be broken on another. Any or all keys may be optional. How absent optional keys are ordered with respect to present keys may be set separately for each key. msort allows you to specify arbitrary sort orders and to define virtu- ally unlimited numbers of multigraphs of effectively unlimited length. The sort order and multigraphs are defined separately for each key. If your system has locale support, you can also use locale collation rules instead of specify your own sort order. msort provides twelve types of key comparison: lexicographic, numeric, numeric string, hybrid, by string length, by angle, by date, by domain name, by time, by ISO8601 date/time stamp, by month name, and random. What month names are used is a bit complicated. If the -s flag is used on the same key and its argument is the name of a file, the month names are read from the file, which should be in the same format as a sort order definition file. If the -s flag is used and its argument is a lo- cale name, the month names recognized will be the month names and ab- breviations associated with the specified locale. If the -s flag is not used the month names recognized will be the month names and abbrevia- tions associated with the current locale. If your system does not have locale support and you do not use the -s flag to read the month names from a file, the month names recognized will be the English month names and abbreviations. msort can reverse the characters in a key, allowing it to be used to generate reverse dictionaries. A choice of sorting algorithms is provided. msort fully supports Unicode. The text to be sorted, and all specifica- tions, should be in UTF-8 Unicode. (If you have plain ASCII text, this is not a problem as ASCII is a subset of Unicode.) Full Unicode case- folding is available, in Turkic and non-Turkic variants. Unicode nor- malization is performed before sorting. For usage information, execute msort with no arguments. Full information about msort is currently to be found in the reference manual, which is distributed as a PDF (Portable Document Format) file.

General options -b,--block A record is terminated by two or more newlines -l,--line A record consists of a single line -r,--record-separator <separator> A record is terminated by separator character -O,--fixed-size-record <bytes> A record consists of the specified number of bytes. -d,--field-separators <character>+ Fields are delimited by the named character(s) -w,--whole Sort on the entire text of the record -a,--algorithm <algorithm> Use the specified sort algorithm. The choices are: I(nsertion- Sort), M(ergeSort), Q(uickSort), and S(hellSort). Note that In- sertionSort and MergeSort are stable, while QuickSort and Shell- Sort are unstable. The default is QuickSort. -M,-initial-maximum-records <records> Set initial maximum number of records -m,--line-end-carriage-return End-of-line in the input data is marked by Carriage Return (0x0D) as on the Macintosh rather than by Line Feed (0x0A) as on Unix systems. -I,--invert-globally Invert sense of comparisons globally -B,--BMP No characters fall outside the Basic Multingual Plane (that is, have values greater than 0xFFFF). -Z,--skip-first-record Copy the first record in the input to the output without sorting it. This is useful for sorting files with a header. -p,--reserve-private-use-area Do not make internal use of the Private Use areas. By default, multigraphs are assigned internally to codepoints in the Supple- mentary Private Use areas if full Unicode is in use or to code- points in the Private Use area if input is restricted to the Ba- sic Multilingual Plane by means of the -B option. If your input makes use of the Private Use areas, this option prevents inter- ference with your input. In this case, multigraphs will be as- signed to the Low and High Surrogate areas (0xD800-0xDFFF). Note that this limits the number of multigraphs to 2,048. -P,--random-seed <seed> Set the seed for the random number generator. If not set here, it is set to a value determined by the time. The seed used is reported in the log. This option allows runs to be replicated. -Q,--check-only Check whether the input is already sorted. Do not generate any output. Exit status is 0 if input is already sorted, 11 if not sorted. -1,--in <input file name> -2,--out <output file name> If the output file is the same as the input file, the input file will be overwritten. The input file will not be overwritten if the run is unsuccessful. -j,--suppress-log Suppress output to the log. If this flag is given before there is any output to the log from a command line flag, nothing will be written to the log and the log file will not be created. If a command line flag generates a log message before this flag is processed, the log file will be created but no log messages will be written to it once this flag is processed. To guarantee that no attempt will be made to open a log file, give this flag first. -q,--quiet Be quiet - do not chat while working -u,--unicode-normalization <mode> Select Unicode normalization mode. The choices of mode are: c for normalization form C (NFC), d for normalization form D (NFD), C for normalization form KC (NFKC), D for normalization form KD (NFKD), and n for no normalization. The default is NFC. Key specific options -e,--character-range <m,n> Sort on characters m through n. Positive indices start from one. Negative indices indicate position with respect to the end of the record. For example, the range 3,-2 consists of the third character through the next-to-last character. -n,--position <POS>(,<POS>) Sort on the specified POS or contiguous range of POSs, where a POS is of the form <field number>(.<character number>). Both counts begin at one. Field numbers but not character numbers may be negative, in which case they are counted from the right. Thus, 1.2 is the second character of the first field; -2.1 is the first character of the next to last field. -t,--tag <tag regexp> Sort on the field with the specified tag -o,--optional <comparison> Optional: compare as (<,=,>) to present key if absent -C,--fold-case Fold case -z,--fold-case-turkic Fold case with additional Turkic conversions. -c,--comparison-type <comparison type> a(ngle),l(exicographic), i(so8601 date/time), t(ime), D(omain name/email address), d(ate), m(onth name), n(umeric), N(umeric string),s(ize), h(hybrid), r(andom) -y,--number-system <number system> Specifies the number system expected for this key. This affects only numeric and numeric string keys. There are two special val- ues. If the number system is "all", records may contain any num- ber system that msort can interpret. Different records may con- tain different number systems. If the number system is "any", records may contain any writing system that msort can interpret, but all records must make use of the same number system. msort sets the number system on the basis of the first record. -f,--date-format <date format> Permutation of ymd with separators, e.g. y-m-d for international date format, m/d/y for American date format, or a permutation of yd with separators, e.g. y-d, for day-of-year dates. All three components may be numbers in any available number system. The month field may also be a month name, determined by the same de- vices as independent month name fields. -W,--sort-order-file-separators <file name> Read the list of characters to be treated as separators in the sort order definition file. -S,--substitutions <file name> Read substitutions from named file -s,--sort-order <file name>|<locale name>|"locale" If the argument is a file name, it is taken to be a sort order file and the sort order for the key is read from the file. If the argument is a locale name, the collation rules for that lo- cale are used. If the argument is "locale", the collation rules for the current locale are used. -T,--transformations <(d)(e)(s)> Apply the specified transformations. d specifies that diacrit- ics are to be stripped. Separately encoded combining diacritics are removed. Characters with diacritics represented by single codepoints are replaced with the corresponding ASCII character without the diacritics, if there is one. e specifies that en- closed characters, that is, characters within circles or paren- theses, are to be replaced with the corresponding plain ASCII character if there is one. s specifies that characters in spe- cial styles are to be replaced with the corresponding plain ASCII character if there is one. Stylistic equivalents include: small capitals (e.g. U+1D04), script forms (e.g. U+212C), black letter forms (e.g. U+212D), Arabic presentation forms (e.g. U+FE81), Hebrew presentation forms (e.g. U+FB1D), fullwidth forms (e.g. U+FF01), halfwidth forms (e.g. U+FF7B), and the mathematical alphanumeric symbols (e.g. U+1D400). -x,--exclusion-file <file name> Read exclusions from named file -X,--exclude-characters <exclusions> Exclude specified characters -i,--invert-locally Invert sense of comparisons -R,--reverse-key Reverse characters of key -A,--first-character-only Ignore all but the first character of the field, after substitu- tions, exclusions, etc. Note: long options may not be available on your system.
