Spawning a TTY Shell

  1. The first thing to do is use python3 -c 'import pty;pty.spawn("/bin/bash")', which uses Python to spawn a better-featured bash shell. At this point, our shell will look a bit prettier, but we still won’t be able to use tab autocomplete or the arrow keys, and Ctrl + C will still kill the shell.

  2. Step two is: export TERM=xterm – this will give us access to term commands such as clear.

  3. Finally (and most importantly) we will background the shell using Ctrl + Z. Back in our own terminal we use stty raw -echo; fg. This does two things: first, it turns off our own terminal echo (which gives us access to tab autocompletes, the arrow keys, and Ctrl + C to kill processes). It then foregrounds the shell, thus completing the process.

python -c 'import pty; pty.spawn("/bin/sh")'

echo os.system('/bin/bash')

/bin/sh -i

perl β€”e 'exec "/bin/sh";'

perl: exec "/bin/sh";

ruby: exec "/bin/sh"

lua: os.execute('/bin/sh')

(From within IRB)
exec "/bin/sh"

(From within vi)

(From within vi)
:set shell=/bin/bash:shell
