DECORATE(1) User Commands DECORATE(1) NAME decorate - convert fields of various formats SYNOPSIS decorate [OPTION]... [INPUT] decorate --decorate [OPTION]... [INPUT] decorate --undecorate N [OPTION]... [INPUT] DESCRIPTION Converts (and optionally sorts) fields of various formats With --decorate: adds the converted fields to the start of each line and prints and prints it to STDOUT; does not sort. With --undecorate: removes the first N fields from the input; Use as post-processing step after sort(1). Without --decorate and --undecorate: automatically decorates the input, runs sort(1) and undecorates the result; This is the easiest method to use. The decorate program allows sorting input according to various ordering, e.g. IP addresses, roman numerals, etc. It works in tandem with sort(1) to perform the actual sorting. The idea was suggested by Pdraig Brady in https://lists.gnu.org/r/bug- coreutils/2015-06/msg00076.html: 1. Decorate: convert the input to a sortable-format as additional fields 2. Sort according to the inserted fields 3. Undecorate: remove the inserted fields OPTIONS General Options: --decorate decorate/convert the specified fields and print the output to STDOUT. Does not automatically run sort(1) or undecorates the output --header=N does not decorate or sort the first N lines -H same as --header=N -k, --key=KEYDEF key/field to sort; same syntax as sort(1), optionally followed by ':method' to convert to the field into a sortable value; see examples and available conversion below -t, --field-separator=SEP use SEP instead of non-blank to blank transition --print-sort-args print adjusted parameters for sort(1); Useful when using --deco- rate and then manually running sort(1) --undecorate=N removes the first N fields -z, --zero-terminated line delimiter is NUL, not newline --sort-cmd=/path/to/sort Alternative sort(1) to use. --help display this help and exit --version output version information and exit The following options are passed to sort as-is (Most of them assume GNU sort): -c, --check --compress-program --random-source -s, --stable --batch-size -S, --buffer-size -T, --temporary-directory -u, --unique --parallel Available conversions methods (use with -k): as-is copy as-is roman roman numerals strlen length (in bytes) of the specified field ipv4 dotted-decimal IPv4 addresses ipv6 IPv6 addresses ipv4inet number-and-dots IPv4 addresses (incl. octal, hex values) ipv6v4map IPv6 and IPv4 (as IPv4-Mapped IPv6) addresses ipv6v4comp IPv6 and IPv4 (as IPv4-Compatible IPv6) addresses EXAMPLES Example of preparing to sort by roman numerals: $ printf "%s\n" C V III IX XI | decorate -k1,1:roman --decorate 0000100 C 0000005 V 0000003 III 0000009 IX 0000011 XI The output can now be sent to sort(1), followed by removing (=undeco- rate) the first field. $ printf "%s\n" C V III IX XI \ | decorate -k1,1:roman --decorate \ | sort -k1,1 \ | decorate --undecorate 1 III V IX XI C decorate(1) can automatically combine the decorate-sort-undecorate steps (when run without --decorate or --undecorate): $ printf "%s\n" C V III IX XI | decorate -k1,1:roman III V IX XI C ADDITIONAL INFORMATION See GNU Datamash Website (https://www.gnu.org/software/datamash) AUTHOR Written by Assaf Gordon, Shawn Wagner and Erik Auerswald.
