JEXEC(8)		FreeBSD	System Manager's Manual		      JEXEC(8)

NAME
     jexec -- execute a	command	inside an existing jail

SYNOPSIS
     jexec [-l]	[-u username | -U username] jail [command ...]

DESCRIPTION
     The jexec utility executes	command	inside the jail	identified by its jid
     or	name.  If command is not specified then	the user's shell is used.

     The following options are available:

     -l	     Execute in	a clean	environment.  The environment is discarded
	     except for	HOME, SHELL, TERM, USER, and anything from the login
	     class capability database for the user.

     -u	username
	     The user name from	host environment as whom the command should
	     run.

     -U	username
	     The user name from	jailed environment as whom the command should
	     run.

SEE ALSO
     jail_attach(2), jail(8), jls(8)

HISTORY
     The jexec utility was added in FreeBSD 5.1.

BUGS
     If	the jail is not	identified by jid there	is a possible race in between
     the lookup	of the jail and	executing the command inside the jail.	Giving
     a jid has a similar race as another process can stop the jail and start
     another one after the user	looked up the jid.
