Similar: using it to get syslog out of self-chrooting ssh with minimal trauma: socat -u UNIX-RECV:/home/sftponly/user/dev/log,mode=666 UNIX-SENDTO:/dev/log

It's also an CLI IMAPS client, with history: socat READLINE,history=$HOME/.imaps_history EXEC:'"openssl s_client -connect mailserver:993"'

or a CLI web browser with history: socat -d -d READLINE,history=$HOME/.http_history TCP4:www.domain.com:www,crnl

or, if you have to interact with something that has no readline, say sendmail: socat READLINE EXEC:"sendmail -bt"
