9.10 Invoking the `msgexec' Program
msgexec [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'.
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
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.
9.10.1 Input file location
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.
9.10.2 Input file syntax
Assume the input file is a Java ResourceBundle in Java
`.properties' syntax, not in PO file syntax.
Assume the input file is a NeXTstep/GNUstep localized resource
file in `.strings' syntax, not in PO file syntax.
9.10.3 Informative output
Display this help and exit.
Output version information and exit.
