+# NAME
+docker-exec - Run a command in a running container
+
+# SYNOPSIS
+**docker exec**
+[**-d**|**--detach**]
+[**--detach-keys**[=*[]*]]
+[**--help**]
+[**-i**|**--interactive**]
+[**--privileged**]
+[**-t**|**--tty**]
+[**-u**|**--user**[=*USER*]]
+CONTAINER COMMAND [ARG...]
+
+# DESCRIPTION
+
+Run a process in a running container.
+
+The command started using `docker exec` will only run while the container's primary
+process (`PID 1`) is running, and will not be restarted if the container is restarted.
+
+If the container is paused, then the `docker exec` command will wait until the
+container is unpaused, and then run
+
+# OPTIONS
+**-d**, **--detach**=*true*|*false*
+    Override the key sequence for detaching a container. Format is a single character `[a-Z]` or `ctrl-<value>` where `<value>` is one of: `a-z`, `@`, `^`, `[`, `,` or `_`.
+
+**--detach-keys**=""
+  Define the key sequence which detaches the container.
+
+**--help**
+  Print usage statement
+
+**-i**, **--interactive**=*true*|*false*
+   Keep STDIN open even if not attached. The default is *false*.
+
+**--privileged**=*true*|*false*
+   Give the process extended [Linux capabilities](http://man7.org/linux/man-pages/man7/capabilities.7.html)
+when running in a container. The default is *false*.
+
+   Without this flag, the process run by `docker exec` in a running container has
+the same capabilities as the container, which may be limited. Set
+`--privileged` to give all capabilities to the process.
+
+**-t**, **--tty**=*true*|*false*
+   Allocate a pseudo-TTY. The default is *false*.
+
+**-u**, **--user**=""
+   Sets the username or UID used and optionally the groupname or GID for the specified command.
+
+   The followings examples are all valid:
+   --user [user | user:group | uid | uid:gid | user:gid | uid:group ]
+
+   Without this argument the command will be run as root in the container.
+
+The **-t** option is incompatible with a redirection of the docker client
+standard input.
