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:
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
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?
