! .SH DESCRIPTION
! .PP
! The \f[CB]jcmd\f[R] utility is used to send diagnostic command requests to
! the JVM.
! It must be used on the same machine on which the JVM is running, and
! have the same effective user and group identifiers that were used to
! launch the JVM.
! Each diagnostic command has its own set of arguments.
! To display the description, syntax, and a list of available arguments
! for a diagnostic command, use the name of the command as the argument.
! For example:
! .RS
! .PP
! \f[CB]jcmd\f[R] \f[I]pid\f[R] \f[CB]help\f[R] \f[I]command\f[R]
! .RE
! .PP
! If arguments contain spaces, then you must surround them with single or
! double quotation marks (\f[CB]\[aq]\f[R] or \f[CB]"\f[R]).
! In addition, you must escape single or double quotation marks with a
! backslash (\f[CB]\\\f[R]) to prevent the operating system shell from
! processing quotation marks.
! Alternatively, you can surround these arguments with single quotation
! marks and then with double quotation marks (or with double quotation
! marks and then with single quotation marks).
! .PP
! If you specify the process identifier (\f[I]pid\f[R]) or the main class
! (\f[I]main\-class\f[R]) as the first argument, then the \f[CB]jcmd\f[R]
! utility sends the diagnostic command request to the Java process with
! the specified identifier or to all Java processes with the specified
! name of the main class.
! You can also send the diagnostic command request to all available Java
! processes by specifying \f[CB]0\f[R] as the process identifier.
! .SH COMMANDS FOR JCMD
! .PP
! The \f[I]command\f[R] must be a valid \f[CB]jcmd\f[R] diagnostic command
! for the selected JVM.
! The list of available commands for \f[CB]jcmd\f[R] is obtained by running
! the \f[CB]help\f[R] command (\f[CB]jcmd\f[R] \f[I]pid\f[R] \f[CB]help\f[R])
! where \f[I]pid\f[R] is the process ID for a running Java process.
! If the \f[I]pid\f[R] is \f[CB]0\f[R], commands will be sent to all Java
! processes.
! The main class argument will be used to match, either partially or
! fully, the class used to start Java.
! If no options are given, it lists the running Java process identifiers
! that are not in separate docker processes along with the main class and
! command\-line arguments that were used to launch the process (the same
! as using \f[CB]\-l\f[R]).
