The difficult way I think :
take a look at "man getpwent" and write a script.

I'm sure perl must have a module to access this.
Using python, it's rather easy :
>>> import pwd
>>> x = pwd.getpwall()
Now x contains info like :
[('root', '$1$3KagL$aHK65kVdt9gQLJqIx9HUU1', 0, 0, 'Charlie &', '/root',
'/bin/csh'), ('toor', '*', 0, 0, 'Bourne-again Superuser', '/root', ''),
('daemon', '*', 1, 1, 'Owner of many system processes', '/root',
'/nonexistent'), .... etc

simply join the fields with ":"
But note that you still have to add ":0:0" for 2 of the fields
(6th and 7th fields... every entry seems to have these) though
I don't know what they do.

ie. using only getpwall()'s results would produce :
gary:$1$s5oclFll$3244G/:1001:1000::gary:/home/gary:/bin/sh

when the real entry should be :
gary:$1$s5oclFll$3244G/:1001:1000::0:0:gary:/home/gary:/bin/sh
