.TP
\fB\-\-local\fR
Do not attempt to connect to \fBrubygems\.org\fR\. Instead, Bundler will use the gems already present in Rubygems\' cache or in \fBvendor/cache\fR\. Note that if a appropriate platform\-specific gem exists on \fBrubygems\.org\fR it will not be found\.
.
.TP
\fB\-\-print\fR
Prints the lockfile to STDOUT instead of writing to the file system\.
.
.TP
\fB\-\-lockfile=<path>\fR

.SH"UPDATING ALL GEMS"
If you run \fBbundle lock\fR with \fB\-\-update\fR option without list of gems, bundler will ignore any previously installed gems and resolve all dependencies again based on the latest versions of all gems available in the sources\.
.
.SH"UPDATING A LIST OF GEMS"
Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the gems that you specified locked to the versions in the \fBGemfile\.lock\fR\.
.
.P
For instance, you only want to update \fBnokogiri\fR, run \fBbundle lock \-\-update nokogiri\fR\.
.
.P
Bundler will update \fBnokogiri\fR and any of its dependencies, but leave the rest of the gems that you specified locked to the versions in the \fBGemfile\.lock\fR\.
.
.SH"SUPPORTING OTHER PLATFORMS"
If you want your bundle to support platforms other than the one you\'re running locally, you can run \fBbundle lock \-\-add\-platform PLATFORM\fR to add PLATFORM to the lockfile, force bundler to re\-resolve and consider the new platform when picking gems, all without needing to have a machine that matches PLATFORM handy to install those platform\-specific gems on\.
.
.P

.SH"PATCH LEVEL OPTIONS"
See bundle update(1) \fIbundle\-update\.1\.html\fR for details\.
