Cool.


Here's a script i use to generate case
insensitive regexes. It turns

FooBar

into

[Ff][Oo][Oo][Bb][Aa][Rr]

term% cat /bin/uncase
#!/bin/rc

exec awk '{
lower = tolower($0)
upper = toupper($0)
len = length($0)

for( i = 1 ; i <= len ; i++ )
printf "[" substr(upper, i, 1) substr(lower, i, 1) "]"
printf "\n"
}'
