What do you mean? What's wrong with
IFS=';' eval set -- \$rndctl_flags
?
Here's a more complete suggestion:
# Split on semicolons
IFS=';' eval set -- \$rndctl_flags
for args in "$@"; do
# Within a single semicolon-separated segment,
# parse zero or more flags followed by one or more devices.
ceflags='' # one or more of -c/-e/-C/-E
dtflags='' # exactly one of -d/-t
for arg in $args; do
case "$arg" in
-[ceCE])
ceflags="${ceflags}${ceflags:+ }${arg}"
;;
-[dt]
dtflags="${dtflags}${dtflags:+ }${arg}"
;;
-*)
error
;;
*)
# Perform the command with the specified
# device or type name.
# ceflags defaults to "-c -e".
# dtflags defaults to "-d".
dev="$arg"
: ${ceflags:=-c -e}
: ${dtflags:=-t}
$command ${ceflags} ${dtflags} ${dev}
;;
esac
