More fun with vim. Assume you have a vim editor open with multiple files, each of which need to have their lines lexicographically reversed. Is this a contrived example? Sure, but bear with me for a moment. A macro can do this pretty easily and could be recorded via 'q<buffer>', where '<buffer>' is a letter. But recording macros this way can be a bit opaque. Plus, having to manually invoke it for each buffer is suboptimal. Here is one way to do the above: - enter the desired commands on an empty line (such as :1,$ !sort -r^M:w!^M) - review the vim commands and refine as you see fit. - execute the following in normal mode on the same line (to load the 'a' register): 0"ay$ - execute the following ex command (to discard loading the 'a' buffer): :e! - execute the following ex command (to apply 'a' to all buffers): :bufdo normal @a In this example, all buffers in the vim session will have the commands in the 'a' buffer applied (reverse sort their lines and contents saved).
