.Dd May 27, 2009 .Dt JEXEC 8 .Os .Sh NAME .Nm jexec .Nd "execute a command inside an existing jail" .Sh SYNOPSIS .Nm .Op Fl u Ar username | Fl U Ar username .Ar jail command ... .Sh DESCRIPTION The .Nm utility executes .Ar command inside the .Ar jail identified by its jid or name.

p The following options are available: l -tag -width indent t Fl u Ar username The user name from host environment as whom the .Ar command should run. t Fl U Ar username The user name from jailed environment as whom the .Ar command should run. .El .Sh SEE ALSO .Xr jail_attach 2 , .Xr jail 8 , .Xr jls 8 .Sh HISTORY The .Nm utility was added in .Fx 5.1 . .Sh BUGS If the jail is not identified by .Ar jid there is a possible race in between the lookup of the jail and executing the command inside the jail. Giving a .Ar jid has a similar race as another process can stop the jail and start another one after the user looked up the .Ar jid .
