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

NAME
     jexec -- execute a	command	inside an existing jail

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

DESCRIPTION
     The jexec utility executes	command	inside the jail	identified by its jid
     or	name.

     The following options are available:

     -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.
