uncomment line in file

[hoize]

Hello!

I want to uncomment a line in a file, for example:

/root/.bashrc

# export LS_OPTIONS='--color=auto'

after change:

export LS_OPTIONS='--color=auto'

After some searching for a solution, I found the Augeas-Tool and then the Augeas-Shellvar-Provider.

So I tried it:

  shellvar { "export LS_OPTIONS":

    ensure  =>  present,

    target  =>  "/root/.bashrc",

    uncomment =>  true,

  }

But I always get this error, regardless how I paraphrase the ressource "shellvar".

An alternative solution would be great, too. But with the file_line ressource, I can't imagine, that there is an very short and easy way.

I hope someone can help me! 

Thank You!

Hi Hoize,

Since we're talking about a comment, does it really matter if it is
still in the file? Bash certainly does not think so. The file_line()
function should work well for you if you want to manage individual lines
as opposed to the entire file. I would recommend this approach for its
simplicity instead of Augeas.

Best regards,

Hi Garrett,

do you mean to add the lines again, with file_line? I thought about this option, too. 

It would be a great way to uncomment this lines, but if it is easier with file_line, I will do it so.

Maybe this (not tested):


file_line { 'uncomment-line-in-bashrc':
path => '/root/.bashrc',
line => "export LS_OPTIONS='--color=auto' # Uncommented by Puppet",
match => '^#?[[:space:]]*export LS_OPTIONS=.*$',
}


file_line is provided by the stdlib (which should be installed of course).
HTH.
