NAME¶

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

VERSION¶

version 1.043

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"'

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.

-verbose

Show effect of the modify instructions.

Examples¶

 $ cme modify ssh 'Host:"*.work.com" IdentityFile:="~/.ssh/id_work"'

 $ cme modify dpkg-control 'binary:~".*" Architecture=any'

 $ cme modify dpkg 'control binary:~".*" Architecture=any'

Re-use your one-liners¶

These modification instructions can be re-used once they are stored in a run script (See App::Cme::Command::run for details).

The following one-liner:

 $ cme modify dpkg 'control binary:~".*" Architecture=any'

can be stored in "~/.cme/scripts/set-arch-as-any":

  app: dpkg-control
  load: binary:~".*" Architecture=any

and then run with:

  $ cme run set-arch-as-any
