Subject: passing modified parameter list to child
Date: Mon, 02 Jul 2012 18:13:11 +0200 [thread overview]
Message-ID: <1341245591.9491.140661096848393.5D4572DC@webmail.messagingengine.com> (raw)
I have two scripts, master and slave. When the master script calls the
slave script, it should pass all arguments to the slave (like in "$@"),
with the following twist: If the LAST argument of master does NOT start
with a dash, this argument should get a prefix "--use=".
For example, if the user calls
master --foo --bar=baz abcd
this should be turned into
slave --foo --bar=baz --use=abcd
but a call
master -x -y
should just become
slave -x -y
Of course I can solve this "the brute force way", i.e.
- Assign "$@" to an array,
- Test the last parameter whether it starts with a dash,
- If yes, prefix it with "--use"
- Pass the array to slave.
However, given the plethora of array- and string-manipulation features
of zsh, I was wondering whether there is a more "zsh-like" way to do it.
Any suggestions? You don't need to present a complete solution to the
problem; just a few ideas would already help.
Ronald
