I would definitely like to hear about these 'better, faster and simpler ways'. As I said, I'm new to UNIX and there are plenty of stuff to learn so any advice would be appreciated. The whole script is ~100 lines, so I probably won't paste it here. But if you like to know what other fields of that line are used for, then here it is:
PIN000 - Three last digits are used as a password for user's account (I use PIN in front so the user's entry is more easily read, though I would like to encrypt this field in the future for security reasons.
FirstName.LastName - Used to identify the user.
AccountNumber - I don't use this one for now, but this is a fixed length number. I plan to use this number for transactions between users within the system.
Basically, it's just a simple script used to manage users' finances in a simple 'deposit' 'withdraw' manner. However, it's very limited as of now, cause all the changes done by the user are not saved into his/her user entry (that line in the file).

Hi,
I'm attempting to rename some files that have spaces in them. Without linking sed commands together is it possible to replace the first three "." to " ".
