SYNOPSIS

recode [OPTION]... [ [CHARSET] | REQUEST [FILE]... ]

DESCRIPTION

Free ‘recode’ converts files between various character sets and surfaces.

If a long option shows an argument as mandatory, then it is mandatory for the equivalent short option also. Similarly for optional arguments.

Listings:
−l, −−list[=FORMAT]

list one or all known charsets and aliases

−k, −−known=PAIRS

restrict charsets according to known PAIRS list

−h, −−header[=[LN/]NAME]

write table NAME on stdout using LN, then exit

−F, −−freeze−tables

write out a C module holding all tables

−T, −−find−subsets

report all charsets being subset of others

−C, −−copyright

display Copyright and copying conditions

−−help

display this help and exit

−−version

output version information and exit

Operation modes:
−v, −−verbose

explain sequence of steps and report progress

−q, −−quiet, −−silent

inhibit messages about irreversible recodings

−f, −−force

force recodings even when not reversible

−t, −−touch

touch the recoded files after replacement

−i, −−sequence=files

use intermediate files for sequencing passes

−−sequence=memory

use memory buffers for sequencing passes

−p, −−sequence=pipe

use pipe machinery for sequencing passes

Fine tuning:
−s, −−strict

use strict mappings, even loose characters

−d, −−diacritics

convert only diacritics or alike for HTML/LaTeX

−S, −−source[=LN]

limit recoding to strings and comments as for LN

−c, −−colons

use colons instead of double quotes for diaeresis

−g, −−graphics

approximate IBMPC rulers by ASCII graphics

−x, −−ignore=CHARSET

ignore CHARSET while choosing a recoding path

Option −l with no FORMAT nor CHARSET list available charsets and surfaces. FORMAT is ‘decimal’, ‘octal’, ‘hexadecimal’ or ‘full’ (or one of ‘dohf’). Unless DEFAULT_CHARSET is set in environment, CHARSET defaults to the locale dependent encoding, determined by LC_ALL, LC_CTYPE, LANG. With −k, possible before charsets are listed for the given after CHARSET, both being tabular charsets, with PAIRS of the form ‘BEF1:AFT1,BEF2:AFT2,...’ and BEFs and AFTs being codes are given as decimal numbers. LN is some language, it may be ‘c’, ‘perl’ or ‘po’; ‘c’ is the default.

REQUEST is SUBREQUEST[,SUBREQUEST]...; SUBREQUEST is ENCODING[..ENCODING]... ENCODING is [CHARSET][/[SURFACE]]...; REQUEST often looks like BEFORE..AFTER, with BEFORE and AFTER being charsets. An omitted CHARSET implies the usual charset; an omitted [/SURFACE]... means the implied surfaces for CHARSET; a / with an empty surface name means no surfaces at all. See the manual.

If none of −i and −p are given, presume −p if no FILE, else −i. Each FILE is recoded over itself, destroying the original. If no FILE is specified, then act as a filter and recode stdin to stdout.
