To change the text inside a file to lower case:

Step one: edit the file using "vi"

Step two: position to start of text to be changed to lower case

Step three: type !} tr [A-Z] [a-z]

Comment by mpb 188 weeks and 4 days ago
lower () { tr [A-Z] [a-z]; } # convert stdin to lower case

Usage:

echo hELLO wORLD |lower

hello world
