I have a daemon that can be run manually from a bash shell like this:
daemon-binary --name some-name --separator '' /path/to/file
The command-line options for this daemon should be configured in /etc/default/daemonname
like this:
DAEMON_OPTS="--name some-name --separator '' /path/to/file"
This config is sourced by an init-script that starts the daemon passing the commandline options found in DAEMON_OPTS
like this:
daemon-binary "$DAEMON_OPTS"
The result is, that the string ''
gets quoted again and instead of an empty string the daemon-binary
gets passed two single. So in fact the result is the same as calling:
daemon-binary --name some-name --separator "''" /path/to/file
As far as I understand bash splits the DAEMON_OPTS
at each whitespace, then quotes all the pieces and passes them to the daemon-binary
.
Is there any way to write the bash variable DAEMON_OPTS
such that what's currently being expanded to "''"
will be expanded into an empty string?
