NAME

       knife-diff - The man page for the knife diff subcommand.

       The knife diff subcommand is used to compare the differences between files and directories
       on the server and in the chef-repo. For example, to compare files on the server  prior  to
       an  uploading  or downloading files using the knife download and knife upload subcommands,
       or to ensure that certain files in multiple production environments  are  the  same.  This
       subcommand  is  similar  to  the  git diff command that can be used to diff what is in the
       chef-repo with what is synced to a git repository.

       Common Options

       The following options can be run with all Knife sub-commands and plug-ins:

       -c CONFIG, --config CONFIG
              The configuration file to use.

       --color
              Indicates that colored output will be used.

       -d, --disable-editing
              Indicates that $EDITOR will not be opened; data will be accepted as-is.

       --defaults
              Indicates that Knife will use the default  value,  instead  of  asking  a  user  to
              provide one.

       -e EDITOR, --editor EDITOR
              The $EDITOR that is used for all interactive commands.

       -E ENVIRONMENT, --environment ENVIRONMENT
              The  name  of  the environment. When this option is added to a command, the command
              will run only against the named environment.

       -f FILE_NAME, --file FILE_NAME
              Indicates that the private key will be saved to a specified file name.

       -F FORMAT, --format FORMAT
              The output format: summary (default), text, json, yaml, and pp.

              Shows help for the command.

       -k KEY, --key KEY
              The private key that Knife will use to sign requests made by the API client to  the
              server.

       --no-color
              Indicates that color will not be used in the output.

       -p PASSWORD, --password PASSWORD
              The user password.

       --print-after
              Indicates that data will be shown after a destructive operation.

       -s URL, --server-url URL
              The URL for the server.

       -u USER, --user USER
              The  user name used by Knife to sign requests made by the API client to the server.
              Authentication will fail if the user name does not match the private key.

       -v, --version
              The version of the chef-client.

       -V, --verbose
              Set for more verbose outputs. Use -VV for maximum verbosity.

       -y, --yes
              Indicates that the response to all confirmation prompts will  be  "Yes"  (and  that
              Knife will not ask for confirmation).

       Syntax

       This argument has the following syntax:

       $ knife diff [PATTERN...] (options)

       Options

       This subcommand has the following options:

       --chef-repo-path PATH
              The  path  to  the  chef-repo.  This  setting will override the default path to the
              chef-repo. Default: same as specified by chef_repo_path in config.rb.

       --cookbook-version VERSION
              The version of a cookbook to be downloaded.

       --concurrency
              The number of allowed concurrent connections. Default: 10.

       --diff-filter=[(A|D|M|T)...[*]]
              Indicates that files will be selected  that  have  been  added  (A),  deleted  (D),
              modified  (M),  and/or  have  had their type changed (T). Any combination of filter
              characters may be used, including no filter characters. Use * to select  all  paths
              if a file matches other criteria in the comparison. Default value: nil.

       --name-only
              Indicates that only the names of modified files will be shown.

       --name-status
              Indicates  that  only the names of files with a status of Added, Deleted, Modified,
              or Type Changed will be shown.

       --no-recurse
              Use --no-recurse to disable listing a directory recursively. Default: --recurse.

       --repo-mode MODE
              The layout  of  the  local  chef-repo.  Possible  values:  static,  everything,  or
              hosted_everything.  Use  static  for  just roles, environments, cookbooks, and data
              bags.  By  default,  everything  and  hosted_everything  are  dynamically  selected
              depending on the server type. Default: everything / hosted_everything.

       knife.rb File Settings

       In   addition   to   the   default   settings   in   a  knife.rb  file,  there  are  other
       subcommand-specific settings that can be added. When a subcommand is run, Knife will use:

       1. A value passed via the command-line

       2. A value contained in the knife.rb file

       3. The default value

       A value passed via the command line will override a value in the knife.rb file; a value in
       a knife.rb file will override a default value.

       The following knife diff settings can be added to the knife.rb file:

       knife[:chef_repo_path]
              Use to add the --chef-repo-path option.

       knife[:concurrency]
              Use to add the --concurrency option.

       knife[:name_only]
              Use to add the --name-only option.

       knife[:name_status]
              Use to add the --name-status option.

       knife[:recurse]
              Use to add the --recurse option.

       knife[:repo_mode]
              Use to add the --repo-mode option.

       Examples

       To compare the "base.json" role to a "webserver.json" role, enter:

       $ knife diff roles/base.json roles/webserver.json

       To  compare  the  differences  between  the  local chef-repo and the files that are on the
       server, enter:

       $ knife diff

       To diff a node named node-lb and then only return files that  have  been  added,  deleted,
       modified, or changed, enter:

       $ knife diff --name-status node-lb

       to return something like:

       node-lb/recipes/eip.rb
       node-lb/recipes/heartbeat-int.rb
       node-lb/templates/default/corpsite.conf.erb
       node-lb/files/default/wildcard.node.com.crt
       node-lb/files/default/wildcard.node.com.crt-2009
       node-lb/files/default/wildcard.node.com.key
       node-lb/.gitignore
       node-lb/Rakefile
