The `importas` program

+ +

+importas replaces a literal with the value of an +environment variable, then executes another program. +

+ +

Interface

+ +

+     importas [ -i | -D default ] [ -s ] [ -C | -c ] [ -n ] [ -d delim ] variable envvar prog...
+

+ +

importas fetches the value of envvar in the +environment. If neither the -D nor the -i option is given, +and envvar is undefined, the null word is returned.
importas then performs +variable substitution on prog..., +with variable as key and that string as value. +
importas then execs into the modified prog....

+ +

Options

+ +

-D default : If envvar is +undefined, and this option is not given, substitute zero word for +variable instead of the empty word; and if it is given, +substitute default instead. To substitute the empty word, +use -D "".
-i : Insist. If envvar is undefined, +importas will not do anything; instead, it will exit 100 with an +error message. This has precedence over any -D option.
Other options are used to control +the substitution mechanism.
