App::Cme::Command::modify(3pm) User Contributed Perl Documentation App::Cme::Command::modify(3pm)

NAME

App::Cme::Command::modify - Modify the configuration of an application

VERSION

version 1.029

SYNOPSIS

  # modify configuration with command line
  cme modify dpkg source 'format="(3.0) quilt"'

DESCRIPTION

Modify a configuration file with the values passed on the command line. These command must follow the syntax defined in Config::Model::Loader (which is similar to the output of cme dump command)

Example:

   cme modify dpkg 'source format="(3.0) quilt"'
   cme modify multistrap my_mstrap.conf 'sections:base source="http://ftp.fr.debian.org"'

Some application like dpkg-copyright allows you to override the configuration file name. You must then use "-file" option:

   cme modify dpkg-copyright -file ubuntu/copyright 'Comment="Silly example"'

Finding the right instructions to perform a modification may be difficult when starting from scratch.

To get started, you can run "cme dump --format cml" command to get the content of your configuration in the syntax accepted by "cme modify":

 $ cme dump ssh -format cml
 Host:"*" -
 Host:"alioth.debian.org"
   User=dod -
 Host:"*.debian.org"
   IdentityFile:="~/.ssh/id_debian"
   User=dod -

Then you can use this output to create instruction for a modification:

 $  cme modify ssh 'Host:"*" User=dod'
 Changes applied to ssh configuration:
 - Host:"*" User has new value: 'dod'

Common options

See "Global Options" in cme.

options

-save
Force a save even if no change was done. Useful to reformat the configuration file.

Show effect of the modify instructions.
