How do i delete all carriage return, spaces, and tabs in sed?

[maltiger]

Man page for sed: https://www.lightnetics.com/post/3334

cat -A nonprintchars 
This is my tab^I$
This is my space $
This is my$
^M$
$
$
$

Use this: cat -A show the end of the line, it is not in the real output.

$ sed -e 's/[ ][^ ]*$//' -e '/^M/d' nonprintchars|cat -A

Result:
This is my$
This is my space$
This is$
$
$
$
