copyfile

Copies a file's contents to the clipboard:

$ copyfile ~/.config/vault/agent.hcl

No more cat file → mouse-select → ⌘C (which mangles long lines and picks up prompt characters), and no more remembering pbcopy < file.

Pro tips​

  • Perfect for pasting configs, logs, or snippets into chats and issue trackers — the paste is byte-exact, including trailing newlines.
  • Combine with process substitution for command output: copyfile <(chezmoi doctor) works because it just reads a file descriptor.
  • On Linux nodes it falls back to xclip/xsel the same way copypath does.
  • If the file is secret-bearing, remember the clipboard is world-readable to local apps — fine on your own Macs, think twice on shared boxes.
