msgexec Programmsgexec [option] command [command-option]
The msgexec program applies a command to all translations of a
translation catalog.
The command can be any program that reads a translation from standard
input. It is invoked once for each translation. Its output becomes
msgexec’s output. msgexec’s return code is the maximum return code
across all invocations.
A special builtin command called ‘0’ outputs the translation, followed by a null byte. The output of ‘msgexec 0’ is suitable as input for ‘xargs -0’.
Add newline at the end of each input line.
During each command invocation, the environment variable
MSGEXEC_MSGID is bound to the message’s msgid, and the environment
variable MSGEXEC_LOCATION is bound to the location in the PO file
of the message. If the message has a context, the environment variable
MSGEXEC_MSGCTXT is bound to the message’s msgctxt, otherwise it is
unbound. If the message has a plural form, environment variable
MSGEXEC_MSGID_PLURAL is bound to the message’s msgid_plural and
MSGEXEC_PLURAL_FORM is bound to the order number of the plural
actually processed (starting with 0), otherwise both are unbound.
If the message has a previous msgid (added by msgmerge),
environment variable MSGEXEC_PREV_MSGCTXT is bound to the
message’s previous msgctxt, MSGEXEC_PREV_MSGID is bound to
the previous msgid, and MSGEXEC_PREV_MSGID_PLURAL is bound to
the previous msgid_plural.
Note: It is your responsibility to ensure that the command can cope
with input encoded in the translation catalog’s encoding. If the
command wants input in a particular encoding, you can in a first step
convert the translation catalog to that encoding using the ‘msgconv’
program, before invoking ‘msgexec’. If the command wants input
in the locale’s encoding, but you want to avoid the locale’s encoding, then
you can first convert the translation catalog to UTF-8 using the
‘msgconv’ program and then make ‘msgexec’ work in an UTF-8
locale, by using the LC_ALL environment variable.
Input PO file.
Add directory to the list of directories. Source files are searched relative to this list of directories. The resulting .po file will be written relative to the current directory, though.
If no inputfile is given or if it is ‘-’, standard input is read.
