Command substitutions in shell commands

[flipsi]

Question: Is there support for command substitutions in shell commands? If not, consider this a feature request.

I tried

:shell echo $(date)

and

:shell echo \$(date)

but I always only see the literal (escaped?) string

$(date)

instead of the desired

My use case is is to create a keybinding to create a copy of a file like this:

  { keys = ["y", "b"], commands = ["shell cp -r %s %s.$(date +%F-%%H%M%S).bak"] }

There isn't support for this yet, but might be currently possible with a bash script and calling the bash script instead

Or maybe just by calling shell bash -c "cp ...."? Then you would not require an additional script file.... Haven't tried that but I guess it should work.

Thank you, that workaround didn't come to mind yet! And yes, it works 👌

Thank you, that'd be elegant, but I can't get it to work with the file substitution (%s).
