Msort sorts files in sophisticated ways. Records may be fixed size, newline-separated blocks, or terminated by any specified character. Key fields may be selected by position, tag, or character range. For each key, distinct exclusions, multigraphs, substitutions, and a sort order may be defined or locale collation rules used. Comparisons may be lexicographic, numeric, numeric string, hybrid, random, by string length, angle, domain name, date, time, month name, or ISO8601 timestamp. Keys may be reversed so as to generate reverse dictionaries. Optional keys are supported. Unicode is supported, including full case-folding. Msort itself has a somewhat complex command line interface, but may be driven by an optional GUI. License: GNU General Public License v3 Changes: The input and output files may now be specified by means of command line options. Another new command line option allows for generation of the log file to be suppressed.
