Unix way' of doing things.
Let's take a small sample file, `dat' containing the words:
top
Eat
opt
tea
Pot
ate
Some words begin with an uppercase character, the step to convert everything to lowercase:
cat dat | tr 'A-Z' 'a-z'Now, do a dictionary sort based on the first word:
cat dat | tr 'A-Z' 'a-z' | sort
Isn't it interesting?
