.SH DESCRIPTION
|
||||
\fBexecve\fP() executes the program pointed to by \fIfilename\fP.
|
||||
\fIfilename\fP must be either a binary executable, or a script
|
||||
starting with a line of the form "\fB#! \fIinterpreter \fR[arg]".

|

.fi
|

In the latter case, the interpreter must be a valid pathname for an
