+ +

The `exec` program

+ +

+exec executes the command line it is given. +

+ +

Interface

+ +

+     exec [ -c ] [ -l ] [ -a argv0 ]prog...
+

+ +

+exec execs into prog.... It does nothing else. +
Without options, exec can be seen as the execline NOP. +

+ +

Options

+ +

-c : empty the environment. prog is executed with no environment variables. Warning: prog will run with an empty PATH, so make sure it does not rely on it.
-l : login. Prepends prog's argv[0] with a dash.
-a argv0 : argv0. Replace prog's argv[0] with argv0. This is done before adding a dash, if the -l option is also present.

+ +

+The exec command, along with its options, is designed to emulate +the standard exec shell builtin, which replaces the shell with the +command it is given. +
