shell script that replaces the command line

[Dave Yost <Dave@xxxxxxxx>]

Hi.

Can a shell function replace the command line contents? I know a widget can do it, but I can’t see a way for a shell function to do that.

The use case is my “d” command I’ve been using for years. It is a fancy shell function that runs a command in the background with all output to a file. Optionally, it can rerun the previously-backgrounded command again or echo it.

When I want to rerun a command, I want my d shell function to put the previously-backgrounded command in the BUFFER so I can edit it before rerunning it.

Thanks

Dave
