What is not clear is not how you call the readline function, but what kind of ``script'' do you assume? a. If it is the normal executable script which can be used as `./script.sh', the question doesn't make sense because there is no command line and no readline. Readline is only enabled in an interactive session of Bash. So one can guess that you are either asking how to enable the readline in a script, or talking about some other type of scripts that you haven't explained. b. If you want to enable readline and accept user inputs, you can use `read -e' as Greg wrote. If you want to control the detailed behavior of `read -e' (i.e., how it behaves for each keystroke) by Bash scripts, the answer is it's impossible. c. Maybe you are thinking of sourcing a script in an interactive shell, such as $ source script.sh In this case, it is still unclear what you want to do because the readline is inactive on the command execution. There is no prompt or command line when the user command is executed. d. Another possibility is that you are talking about the shell commands executed in `bind -x '"keyseq":unix-command''. In this case, it is impossible to invoke a readline function directly from the shell commands. But some limited class of mixed operations can be implemented by combining the `bind '"...":"..."'` macro. e. Or maybe you are thinking of a completely different type of ``script''? -- Koichi
