OK, here is the whole snippet and what it appears to be doing. I still
don't know how:
quoted_args () {
for arg in "$@"; do
esc=`echo "$arg" | sed "s/'/'\\\\\\\\''/g"`
printf " '%s'" "$esc"
done
printf ' ;\n'
}
cmd () {
quoted_args "$@"
}
Then you can something like this:
cmd echo this is crazy
and it outputs this:
'echo' 'this' 'is' 'crazy' ;
Another script takes this output and then does the actual echo (or
whatever command it is you use). Useful for what we are doing, but I'm
still baffled by the sed command. Can anyone explain further?
Thanks,
Bryan
