redirection in nushell

Redirection

Notes

  • Where you see o it means stdout.
  • Where you see e it means stderr.
  • Where you see a it means append.
  • These are all commands, which shouldn't incur parser changes. However, people could find the first 6 strange having the pipe then the redirect.

| command name | stdout | stderr | stdout | stderr | existing file | example usage |

fzf_integration

FZF

Most of this is taken from fzf.fish. A really nice fzf integration with fish-shell.

There's quite a bit of usage of a fish command called commandline. It would be super helpful for porting things like this script if we had such a utility to modify the readline command line buffer.

General Setup

Set the default fzf options

let-env FZF_DEFAULT_OPTS = '--cycle --layout=reverse --border --height=90% --preview-window=wrap --marker="*"'
