Script to fix SSH agent environment variables on a remote server after reconnecting to a screen session

# Script to fix the SSH agent environment variable after reconnecting to a running screen session.
# Usage: *source* this script (don't just execute).
# For example, if you store it at ~/screen-ssh-agent-fix.sh, create this alias to have it available easily:
# alias screenfix='source ~/screen-ssh-agent-fix.sh'

echo "Current value: $SSH_AUTH_SOCK"
