Logging Command Line and Output in Unix

Hi,

This might be a bit stupid question, but what command to use to create like a session which logs the command line, and output on to the screen?

Basically, a log to a file, where I can review what I had install, uninstall, etc.


Thank you

You could use a shell with command history such as bash and pipe every command you use to tee -a with into the same file.

Code:
#bash
# pwd | tee -a sessionfile
# pkgadd -d . SUNWless | tee -a sessionfile
# /etc/init.d/nfs.server start | tee -a sessionfile
# cp $HOME/.bash_history sessionfile.cmds

Hi,

try the script command. It logs into a file until you stop it leaving the session or stopping it with ctrl-d.

Hope that helps,
regards

Thanks ilikecows and zxmaus.

The "script" command look like a better option for me, since keep adding "tee" command at the end is a bit tedious.

I have been working with linux/unix machines for years and have never seen that script command. That is quite handy. Thank you. That will save me a lot of time taking notes and producing documentation for users new to UNIX.

Difficulty: Easy
The Unix philosophy is a computer operating system idea that means the operating system provides a set of basic tools that perform a limited, well-defined function, a unified filesystem as the main method of communication, and a shell scripting and command language to combine modular tools to perform more complex workflows.
