Capitalize inputs

Is there a way you can capitalize the inputs of a string in the perl language?

Is this what you're looking for?

Code:

ada@barnabas:~> perl -e 'print uc( "upper case" ), "\n";'
UPPER CASE

Hi.

Or this? ... cheers, makyo

Code:

% perl -e ' print join(" ", map { ucfirst } split(" ", "my dog has fleas")), "\n";'
My Dog Has Fleas

Here's another...

Code:

perl -pi.bak -e 's/(\w+)/\u\L$1/g' file.txt

I need to capitilize the input from the users input from a question my program asks and I am going to write conditional programming for it and I thought it would be easier to write one compare statement instead of two, cause of the case sensitivity.

for instance if the user types y I want to change it to Y so I do not have to test for lower and upper case character through out my program.

Thank you

Can't you use 'i' command to ignore case

Code:

if ($x =~ /y/i)

how does that i command work I never heard of it.

Hi.

The "i", along with a few other characters, are usually called modifiers because they change the way the matching works. This one causes case to be ignored ... cheers, makyo

It's very easy with Bash.

Code:

#!/bin/bash

echo "What's your name?"
read NAME 

echo $NAME | tr a-z A-Z
