How can I capitalize the first letter of each word?

Question

I need a script in any language to capitalize the first letter of every word in a file.

Thanks for all the answers.

Stackoverflow rocks!

Answer 1

php uses ucwords($string) or ucwords('all of this will start with capitals') to do the trick. so you can just open up a file and get the data and then use this function:

<?php 
$file = "test.txt"; 
$data = fopen($file, 'r');
$allData = fread($data, filesize($file));
fclose($fh);
echo ucwords($allData);
?>

Edit, my code got cut off. Sorry.

Answer 2

perl:

$ perl -e '$foo = "foo bar"; $foo =~ s/\b(\w)/uc($1)/ge; print $foo;'

Foo Bar

Answer 3

From the shell, using ruby, this works assuming your input file is called FILENAME, and it should preserve all existing file formatting - it doesn't collapse the spacing as some other solutions might:

cat FILENAME | ruby -n -e 'puts $_.gsub(/^[a-z]|\s+[a-z]/) { |a| a.upcase }'

Answer 4

This is done in PHP.

$string = "I need a script in any language to capitalize the first letter of every word in a file."
$cap = ucwords($string);

Very basic version for AMOS Basic on the Amiga — only treats spaces as word separators though. I'm sure there is a better way using PEEK and POKE, but my memory is rather rusty with anything beyond 15 years.

FILE$=Fsel$("*.txt")
Open In 1,FILE$
Input #1,STR$
STR$=Lower$(STR$)
L=Len($STR)
LAST$=" "
NEW$=""
For I=0 to L-1
  CUR$=MID$(STR$,I,1)
  If LAST$=" "
    NEW$=NEW$+Upper$(CUR$)
  Else
    NEW$=NEW$+$CUR$
  Endif
  LAST$=$CUR$
Next
Close 1
Print NEW$

I miss good old AMOS, a great language to learn with... pretty ugly though, heh.

In Python, open('file.txt').read().title() should suffice.
