Screen Cheatsheet / Quick Reference (Pocket Friendly)

Escape Key

All screen commands are prefixed by an escape key, by default Ctrl-a (that's Control-a, sometimes written ^a). To send a literal Ctrl-a to the programs in screen, use Ctrl-a a. This is useful when when working with screen within screen. For example Ctrl-a a n will move screen to a new window on the screen within screen.

Description	Command
Basic
Start a new session with session name	screen -S

# Decompressor/compressor for files in Mozilla's "mozLz4" format. Firefox uses this file format to
# compress e. g. bookmark backups (*.jsonlz4).
#

# uncompressed file size [4 bytes, little endian]).
#
# This Python 3 script requires the LZ4 bindings for Python, see: https://pypi.python.org/pypi/lz4
