sudosh is a filter and can be used as a login Unix_shell. sudosh takes advantage of pty devices in order to sit between the user s keyboard and a program, in this case a shell.

sudosh was designed specifically to be used in conjunction with Sudo or by itself as a login shell. sudosh allows the execution of a root or User_account shell with logging. Every command the user types within the root shell is logged as well as the output.

How is this different than sudo -s or sudo /bin/sh

Using sudo -s or other methods doesn t log commands typed to syslog. Generally the commands are logged to a file such as .sh_history and if you use a shell such as csh that doesn t support command-line logging you re out of luck.

sudosh fills this gap. No matter what shell you use, all of the command lines are logged to syslog (including Vi keystrokes.)
