/*! General callback for executing shells.
* The argument is a command followed by arguments as defined in the input syntax.
* Simple example:
* CLIgen input syntax: <a type:int32>, cligen_exec_cb("ls ${a}");
* CLI input: > 42
* Shell command: ls 42
* More advanced example:
* CLIgen input syntax: [<a type:int> | <b type:ipv4addr>],
* cligen_exec_cb("foo.sh ${a:-99} ${b:-1.2.3.4}");
* CLI input: > 22
* Shell command: foo.sh 22 1.2.3.4
* CLI input: > 2.3.4.5
* Shell command: foo.sh 99 1.2.3.4.
