-Since the tools and overall concept are still under heavy development, there are some known limitations applied, in particular only pure x86-64 environment is supported, no IA32 emulation allowed.
+This is a collection of articles describing specific CRIU command line options.
-== Synopsis ==
+== Actions ==
-<pre>
+{{Special:PrefixIndex/CLI/cmd/|stripprefix=1}}
-'crtools' <command> -t <pid> [<options>]
-</pre>
-== Description ==
-'crtools' is command line utility to steer checkpoint and restore procedure.
 == Options ==
-<pre>
+{{Special:PrefixIndex/CLI/opt/|stripprefix=1}}
-<command>::
-    One of the follwong commands
-        * 'dump'
-                to initiate checkpoint procedure
-        * 'restore'
-                to restore previously checkpointed processes
-        * 'show'
-                to decode binary dump files and show their contents in human
-                readable format
-        * 'check'
-                to test whether the kernel support is up-to-date
-        * 'exec'
-                to execute a system call from another task's context
--c::
-    In case of 'show' command the dumped pages content will be shown in hex format.
--D <path>::
-    Use path 'path' as a base directory where to look for dump files set. This
-    commands allpies to any <command>.
--s::
-    Leave tasks in stopped state after checkpoint instead of killing them.
--f <file>::
-    This option is valid for 'show' command only and allows to see content of
-    the <file> specified.
--t <pid>::
-    Checkpoint the whole process tree starting from 'pid'.
--d::
-    Detach 'crtools' itself once restore is complete.
--n <ns>::
-    Checkpoint namespaces. Namespaces must be separated by comma.
-    We now support all namespaces -- uts, ipc, net and mnt
--o <file>::
-    Write logging messages to 'file'.
--v <num>::
-    Set logging level to 'num'. Valid options are: 0 - (silent, error messages
-    only), 1 - informative (default), 2 - debug messages.
-</pre>
-== Examples ==
+== Deprecated stuff ==
-To checkpoint a program with pid 1234 and write all image files into directory checkpoint one should type
+=== Actions ===
+{{Special:PrefixIndex/CLI/deprecated/cmd/|stripprefix=1}}
-<pre>
+=== Options ===
-# crtools dump -D checkpoint -t 1234
+{{Special:PrefixIndex/CLI/deprecated/opt/|stripprefix=1}}
-</pre>
-To restore this program detaching crtools itself, one should type
-<pre>
-crtools restore -d -D checkpoint -t 1234
-</pre>
-"Detaching" (the <code>-d</code> option) here means, that crtools will exit after restoring the processes
-and the latter will get re-parent-ed to the init task.
-To close a file descriptor number 1 in task with pid 1234 run
-<pre>
-crtools exec -t 1234 close 1
-</pre>
-To open a file named /foo/bar for read-write in the task with pid 1234 run
-<pre>
-crtools exec -t 1234 open '&/foo/bar' 2
-</pre>
