osc

A command line tool to access the system clipboard from anywhere using the ANSI OSC52 sequence.

System clipboard access includes writing (i.e. copy) and reading (i.e. paste), even while logged into a remote machine via ssh.

Examples

❯ echo asdf | osc copy

# String 'asdf' copied to clipboard

❯ osc paste
asdf

Usage

Reads or writes the system clipboard using the ANSI OSC52 escape sequence.

Usage:
  osc [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  copy        Copies input to the system clipboard
  help        Help about any command
  paste       Outputs system clipboard contents to stdout
  version     Outputs version information
