%![argument] special text
The argument which trails %! until the end of the line, is
passed to the shell as a command for further processing. But before, all
%?... special texts for replacing particular texts which
are given in argument are interpreted by Gcal.
See section Replacements with date argument %?[date] special texts.
All leading text before the %! special text is processed by Gcal as
usual. If the simple `--debug' respectively `--debug=internal'
option is given at program start-up, informational messages about the executed
command and its exit code will be shown on the standard error
channel
(see section Global options).
If the `--debug=abort' option is given, the Gcal program will be aborted with an error code in case an exit code not equal zero have occurred during the execution of the command. See section Error Codes, and section Global options, for more information.
Use the `--bypass-shell-command' option if you want to see all
%![argument] special texts textually and non-executed
by the shell.
See section Fixed date options,
for more details.
