As others have mentioned, rgw command-line parameter $1 probably has a '/' in it. A simple workaround is to use a different character as the separator. That is: *if* you can assume that variable will not contain the character '|', you can use: sed -e "s|PLACEHOLDER1|$1|' -e "s|PLACEHOLDER2|$2|" < input > output You can use some other characters there as well.
