Changes in file (huge problem)

Changes in file (huge problem)

[Mário Gamito]

Hi,

I have this file in the following format:

tarta 16340309 marsanpin brigittamario@xxx.pt
lms doom123 Luis Miguel Sequeira lms@xxx.pt
jura teste Juraci jgweb@bol.com.br
jsilva t00lt0ya5 Jorge Silva jsilva@xxx.com
tchock  mail#4829 tchock  engDias@xxx.pt
reporterx noname Duarte Oliveira mtbf99@xxx.com
erkulix brunoverab4 Bruno Cruz

First field is a username;
Second field is a password in clear text;
*Last field is the email;
The field between is the name.

As you can see, some lines don't have the name, and names have an unknow 
number of words.
Some lines don't have the e-mail.

What i need is:
Change the second field to the correspondent md5 hash.
Insert foo@foo.foo in the end of the lines that have no email.
Insert the string "NO_NAME" in the ones that don't have a name in it's 
field.
Substitute spaces for ":", *except* of course the spaces within the name.

I know how to do some of these things, others i don't.

Can someone help me, please ?

Thanks in advance.

Warm Regards,
Mário Gamito

Hi Glynn,

Thank you so much for your answer.

I've used your code in a script and run:
# cat passwords.sql | your_script

but all i get is a file named typescrypt with this content:
Script started on Sun Dec 24 23:24:28 2006

What am i doing wrong ?

Warm Regards,
Mário Gamito

... ciao:

: Change the second field to the correspondent md5 hash.

    i have no idea how to do that, so it's left to the reader.


=====  start code  =====

#!/bin/sh

#	process user

#	snag email and/or name

In exchange for your info here's this one:
MD5=`md5 -s "$PASSWORD" | cut -f4 -d' '`

Lucky me that i am in FreeBSD.
BSD's md5 has the "-s" option to hash a string instead of a file.

Linux's md5sum doesn't.
It would require a little more hocus pocus :P

Warm Regards,

Did you call my script "script" by any chance?

If you run:

	cat passwords.sql | script

It will run /usr/bin/script (which logs a terminal session to a file
typically named "typescript").

If the script is in the current directory, you would need to use e.g.:

	cat passwords.sql | ./script
or:
	./script < passwords.sql

Also, it needs the execute bit set ("chmod +x") to be run directly;
you can also call sed explicitly e.g.:

	sed -f script < passwords.sql
