i m a new linux user. working on a mail server having having redhat 7.2 installed on it. I want to display email_ids created by us on our web server. Is there any way by which i can extract necessary data from passwd file on linux system and get this information directly uploaded in master database running on oracle. In other words can i extract selective information like emailids and pno from passwd file through a script and create a database which can be merged with master database. Is their any utility available in linux which can help in this.

Hi, and welcome to LQ!

I don't think that this task is common enough for anyone to have written
a utility for it. Your specs are a bit thin, too. Oracle (which version
are you using, btw?) has built-in features that allow execution of code
at given times (similar to cron). You can write an Oracle Perl script
that reads /etc/passwd and updates a table. ... there's more than one
way to skin this cat.


Cheers,
