7.4.4 Checking programs
--check-programs is similar to
--list-components but works on backend programs and not on
components. It runs each program to test whether it is installed and
runnable. This also includes a syntax check of all config file options
of the program.
The command argument
--check-programs lists all available
programs, one per line. The format of each line is:
- This field contains a name tag of the program which is identical to the
name of the component. The name tag is to be used verbatim. It
is thus not in any escaped format. This field may be empty to indicate
a continuation of error descriptions for the last name. The description
and pgmname fields are then also empty.
- The string in this field contains a human-readable description
of the component. It can be displayed to the user of the GUI for
informational purposes. It is percent-escaped and
- The string in this field contains the absolute name of the
program's file. It can be used to unambiguously invoke that program.
It is percent-escaped.
- The boolean value in this field indicates whether the program is
installed and runnable.
- The boolean value in this field indicates whether the program's
config file is syntactically okay.
- If an error occurred in the configuration file (as indicated by a false
value in the field
okay), this field has the name of the failing
configuration file. It is percent-escaped.
- If an error occurred in the configuration file, this field has the line
number of the failing statement in the configuration file.
It is an unsigned number.
- If an error occurred in the configuration file, this field has the error
text of the failing statement in the configuration file. It is
percent-escaped and localized.
In the following example the dirmngr is not runnable and the
configuration file of scdaemon is not okay.
$ gpgconf --check-programs
gpg:GPG for OpenPGP:/usr/local/bin/gpg2:1:1:
gpgsm:GPG for S/MIME:/usr/local/bin/gpgsm:1:1:
--check-options component will verify the
configuration file in the same manner as
only for the component component.
