USING SED OR VI TO CHANGE CASE

[johngiggs]

I have forgotten how to change all uppercase letters in a file to lowercase using vi and sed. Can someone please refresh my memory?

Thanks,

John

Can someone please tell me how to do it with sed? I think it's something like:

sed 's/[A-Z]/[a-z]/g'

Thanks,

John

try

y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/

Check my typing to make sure I got all the letters on order

or use

tr '[A-Z]' '[a-z]'
