Zsh or Bash: Pass all command output through pager like app automatically?

Question

Is there a way in bash or zsh to automatically pipe all output from any commands I run through another program?

For example, if I ran this command

$ cat /tmp/it

I'd like it to run like I had written it like so:

$ cat /tmp/it | tee /tmp/cmdoutput

where the | tee /tmp/cmdoutput part could be any command at all. My use cases are for colorization and for saving output for commands I run so I can edit them in vim, or search them in vim. I do these things already manually but want to know if there's a way to do this automatically, and am looking for a general solution!

Use the script command :

script makes a typescript of everything displayed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1).

If the argument file is given, script saves the dialogue in this file. If no filename is given, the dialogue is saved in the file typescript.

When you are ready to start recording a log file, type:

script /tmp/cmdoutput

Now, until you stop the script, all input and output in the Terminal will be stored in cmdoutput. When you are done, just type:

exit
