Removing control characters from a text file

Question

I started a unix keystroke log with script temp.txt; however, it captures my keystrokes verbatim (backspaces, arrows, etc...). What is the best way to remove the control characters from a file named temp.txt that I created with script temp.txt?

NOTE: I am answering my own question

Answer 1

This does the job...

cat temp.txt | col -bx > no_control_chars.txt
