[sf-lug] My favorite simple little Linux tips

[Alex Kleider]

try it, Jim:
$ ls my_file
$ ^ls^less

and then watch the magic on the screen:-)
(substitute an existing short text file for "my_file")

It's similar to 
:s/old_string/new_string
when using vim

..by the way, I did not know about this and am very happy to learn about it and some of the other tips that have been mentioned in this thread.
Thanks to the contributers.
Does anyone else have similar tips that some of us newer to Linux may have forgotten or never known?

cheers,
alex
