Here's what I use which has been pulled from various answers in the forum.
Bascially there's a function for deleting a line, appending a line if not
already there and near the bottom one for editing a line. So the way this
works is that this file gets run as part of the base_class to set up the
definition statements and then whenever you need to make a mod such as
replacing a line just include the commented bit at the end (uncommenting it
first, of course)
#
# edit_file.pp
case $operatingsystem {
RedHat,suse: { $sedcommand="/bin/sed" }
solaris: { $sedcommand="/opt/csw/bin/gsed"}
}
define delete_line($file, $pattern) {
exec { "$sedcommand -r -i '/$pattern/d' $file":
onlyif => "/bin/grep '$pattern' '$file'",
}
}
# call the above somewhere else using the following:-
# import "edit_file.pp"
# delete_line { title:
# file => "/path/to/file",
# pattern => "InsertRegExpHere",
# }
define append_if_no_such_line($file, $line, $refreshonly = 'false') {
exec { "/bin/echo '$line' >> '$file'":
#unless => "/bin/grep -Fxqe '$line' '$file'",
unless => "/bin/grep '$line' '$file'",
path => "/bin",
refreshonly => $refreshonly,
}
}
# call the above somewhere else using the following:-
# append_if_no_such_line{ motd:
# file => "/etc/motd",
# line => "Configured with Puppet!"}
define replace_line($file, $old_pattern, $new_pattern) {
exec { "$sedcommand -r -i 's/$old_pattern/$new_pattern/' $file":
onlyif => "/bin/grep '$old_pattern' '$file'",
}
}
# call the above somewhere else using the following:-
# import "edit_file.pp"
# replace_line { title:
# file => "/path/to/file",
# old_pattern => "InsertRegExpHere",
# new_pattern => "InsertRegExpHere",
# }
