automatic ssh logger - http://www.commandlinefu.com/commands/view/14883

ssh.sh

# A wrapper around ssh to automatically provide logging and session handling.
# This function runs ssh, which runs screen, which runs script.

# Requirements:
#     * Log sessions on a remote server
#     * Transparent - nothing extra to type
#     * No installation - nothing to copy to the server beforehand

# Features:
#     * Function wrapper delegating to ssh
#         so nothing to remember
#         uses .ssh/config as expected
#         passes your command line option to ssh
#     * Self-contained: no scripts to install on the server
#     * Uses screen(1), so is:
#         detachable
#         re-attachable
#         shareable
#     * Records session using script(1)
#     * Configurable log file location, which may contain variables or whitespace
#         L="$HOME"               # local variable
#         L="\$HOME"              # server variable
#         L="some space"

# Limitations:
#     * Log dir/file may not contain '~' (which would require eval on the server)

{
	# Date format: YYYY-MM-DD_HH:MM
	local DATE="$(date +%F_%H:%M)"

	# Directory for script logs
	# Quoted with '' to prevent shell expansion on local host
	local LOG_DIR='$HOME/logs'

	# Log files are named by date and local user
	local LOG_FILE="${LOG_DIR}/${DATE}-${USER}"

	# Optionally, save script's timing information
	local TIMING="--timing=\"${LOG_FILE}-timing\""

	# add some commands to the ssh command line
	#	Create the log directory
	#	Start script within a screen session
	/usr/bin/ssh -t "$@" "mkdir --parents \"$LOG_DIR\"; screen -xRR -S $USER script --flush ${TIMING} \"$LOG_FILE\""
