Query or set the internal variable that controls the echo state.
It may be the sum of the following values:
Echo commands read from script files.
Echo commands from functions.
Echo commands read from command line.
More than one state can be active at once. For example, a value of 3 is equivalent to the command echo on all.
The value of echo_executing_commands
may be set by the echo
command or the command line option --echo-commands.
When called from inside a function with the "local"
option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
