Read and execute commands from filename in the current shell environment and return
the exit status of the last command executed from filename. If filename does not
contain a slash, file names in PATH are used to find the directory containing file-
name. The file searched for in PATH need not be executed . When bash is not in
posix mode, the current directory is searched if no file is found in PATH. If the
sourcepath option to the shopt builtin command is turned off, the PATH is not
searched. If any arguments are supplied, they become the positional parameters
when filename is executed. Otherwise the positional parameters are unchanged. The
return status is the status of the last command exited within the script (0 if no
commands are executed), and false if filename is not found or cannot be read.
