can puppet check if the string is present in file

[vicki]

Hello,
I need to add the JVM arguments to the script based on some condition.
First I need to check whether the string representing these args is
already there. Can Puppet check the existence a substring and return
with a code just like java indexOf(substr) does?

Thank you.

Look at the 'file_line' custom type in the Puppetlabs Stdlib. The documentation in the file should assist with its usage.

Thank you Gary for your reply. It is actually the substring of the line that I have to check. Here's the sed command that I use:

sed 's/^JVM_OPTS=\"/&\-Xbootclasspath\/p\:\/eng\/x.jar  <sed_test.sh >sed_test_new.sh

As you can see, I am matching this substring   JVM_OPTS+"  at the beginning of the JVM_OPTS line in the script, and inserting my bootclasspath argument right after. I am going to look at your code, and see if I can either get it to work for my case, or come up with something that works.

Thanks!!
