The GNU implementation has a -V -version-sort option which is a natural sort of (version) numbers within text. A true random sort is provided by the Unix utility shuf.

The GNU implementation has a -R -random-sort option based on hashing this is not a full random shuffle because it will sort identical lines together. Joe 5677 Wendy 23456 Adam 12345 Sort in random Include hidden files when using wild cards.Įxamples Sort a file in alphabetical order Specify the number of digits to determine how many digits of each line should be judged. Like -i, but ignore only tabs and spaces. Natural sort of (version) numbers within text Unique processing to suppress all but one in each set of lines having equal keys. Uses char instead of non-blank to blank transition. Use size for the maximum size of the memory buffer. Stabilizes sort by disabling last-resort comparison. Uses OUTPUT file instead of standard output. < 'DEC'.Ĭompares according to string numerical value. Merge only input files are assumed to be presorted.Ĭompares (unknown) < 'JAN' <. Start a key at POS1 (origin 1), end it at POS2 (default end of line) Like -c, but does not report the first bad line.Ĭonsiders only blanks and alphanumeric characters.įold lower case to upper case characters.Ĭompares according to general numerical value.Ĭompare human readable numbers (e.g., 2K 1G). With no FILE, or when FILE is -, the command reads from standard input. The sort command has also been ported to the IBM i operating system. Similar commands are available on many other operating systems, for example a sort command is part of ASCII's MSX-DOS2 Tools for MSX-DOS version 2. This implementation employs the merge sort algorithm. The version of sort bundled in GNU coreutils was written by Mike Haertel and Paul Eggert. In Version 5, Thompson invented "-" to represent standard input. By Version 4 Thompson had modified it to use pipes, but sort retained an option to name the output file because it was used to sort a file in place. This version was originally written by Ken Thompson at AT&T Bell Laboratories. A sort command that invokes a general sort facility was first implemented within Multics.
