murex Shell Docs

Command Reference: exec

Runs an executable


With murex, like most other shells, you launch a process by calling the name of that executable directly. While this is suitable 99% of the time, occasionally you might run into an edge case where that wouldn't work. The primary reason being if you needed to launch a process from a variable, eg

» set exe=uname
» $exe

As you can see here, murex's behavior here is to output the contents of the variable rather then executing the contents of the variable. This is done for safety reasons, however if you wanted to override that behavior then you could prefix the variable with exec:

» set exe=uname
» exec $exe


<stdin> -> exec
<stdin> -> exec -> <stdout>
           exec -> <stdout>


» exec printf "Hello, world!"
Hello, world!
