cdist-type__key_value - Change property values in files
DESCRIPTION
-----------
This cdist type allows you to change values in a key value based config
file.
REQUIRED PARAMETERS
-------------------
value::
The value for the key. Setting the value to __NOTSET__ will remove the key
from the file.
file::
The file to operate on.
delimiter::
The delimiter which seperates the key from the value.
OPTIONAL PARAMETERS
-------------------
key::
The key to change. Defaults to object_id.
EXAMPLES
--------
--------------------------------------------------------------------------------
# Set the maximum system user id
__key_value SYS_UID_MAX --file /etc/login.defs --value 666 --delimiter ' '
# Same with fancy id
__key_value my-fancy-id --file /etc/login.defs --key SYS_UID_MAX --value 666 \
--delimiter ' '
# Enable packet forwarding
__key_value net.ipv4.ip_forward --file /etc/sysctl.conf --value 1 \
--delimiter '='
