I use vim on the command line. I want to use the substitution command to search for and replace characters in the command line I’m currently working on in the CLI.
Here’s merely one example, say I want to rename a file and begin writing a command like so:
mv here_is_a_way_too_long_filename.txt here_is_a_way_too_long_filename.txt
The filename is very long, so for convenience I’ve used tab completion to produce the second filename. Now I want to replace the underscores with something else, for example \ .
I’m using vim in the CLI, so I press ESC to enter (vim) normal mode, go to the start of the second filename, and then press : to enter the command s/_/\ /. FYI, after entering the : here, I’m seeing this:
mv here_is_a_way_too_long_filename.txt here_is_a_way_too_long_filename.txt
execute: s/_/xxx/
→ but I cannot type a space or press return to execute this vim substitution command. In fact, I can only exit this extra execute: line by pressing ^C.
I’ve also tried numerous variations of the substitution command, to no avail:
s/_/xxx/
gs/_/xxx/
%s/_/\\ / ← NB: I can’t actually enter the space here.
s/_/\\s/
s/_/[:space:]/
... and so on
I don’t want to resort to the command history. This post describes doing something similar but for a previous command in the command history.
What I want to end up with (in the above example) is this:
mv here_is_a_way_too_long_filename.txt here\ is\ a\ way\ too\ long\ filename.txt
after which I press enter to execute the mv command in the shell (eg. zsh).
I want to do this with vim in the CLI if possible. Notes on spaces in filenames are outside the scope; assume I’m aware of those perils.
