Evaluate several commands/arguments.
Syntax eval arg ...
The args are read and concatenated together into a single command.
This command is then read and executed by the shell, and its exit status is returned as the value of eval.
If there are no arguments or only empty arguments, the return status is zero.
This is a BASH shell builtin, to display your local syntax from the bash prompt type: help [e]val
