In the following, the Postfix configuration files postfix-map1.cf
and postfix-map2.cf are automatically created from a file credentials.cf
(with login and password) and files that have the non-login
information.
$ cat makefile
all: postfix-map1.cf postfix-map2.cf
postfix-map1.cf: postfix-map1-base.cf credentials.cf
cat postfix-map1-base.cf credentials.cf >postfix-map1.cf.tmp
mv postfix-map1.cf.tmp postfix-map1.cf
postfix-map2.cf: postfix-map2-base.cf credentials.cf
cat postfix-map2-base.cf credentials.cf >postfix-map2.cf.tmp
mv postfix-map2.cf.tmp postfix-map2.cf
Edit credentials.cf (with login credentials). Then use "make" to
update all postfix config files.
$ vi credentials.cf
$ make
cat postfix-map1-base.cf credentials.cf >postfix-map1.cf.tmp
mv postfix-map1.cf.tmp postfix-map1.cf
cat postfix-map2-base.cf credentials.cf >postfix-map2.cf.tmp
mv postfix-map2.cf.tmp postfix-map2.cf
Edit postfix-map1-base.cf only, then use "make" to
update postfix-map1.cf.
$ vi postfix-map1-base.cf
$ make
cat postfix-map1-base.cf credentials.cf >postfix-map1.cf.tmp
mv postfix-map1.cf.tmp postfix-map1.cf
You can use "make" to automate many things.
