zeynep · 01-18-2008, 02:26 PM

hello,
how can i list the users and their own groups seperately at the system

i see as making;

cat /etc/passwd

but i want to see list of groups and their users at the system

Maybe something like:

Code:

# for i in `cat /etc/passwd | cut -d: -f1` ; do id $i ; done

Thank you for your answer

How can i see the passworless of them and keep in an folder is ther any special command or this kind of thing

Code:

# for i in `cat /etc/passwd | cut -d: -f1` ; do id $i ; done > /path/to/my/file

Everytime you run this, the contents of /path/to/my/file will be updated. You can view/edit the file with whatever editor/viewer of your choice.

On a modern Linux system there should not be any passwords in the /etc/passwd file.

You might be looking at the /etc/shadow file which lists the encrypted/hashed password for the user.

How about an awk version?

Code:

awk -F: '{print $1:$5}' /etc/passwd > /path/to/my/file

Cheers,

hello,
i tried to use awk when i wrote

awk -F : '{ print $1:$5 }' I'm getting error

i couldnt solve yet any idea?

Tinkster · 01-19-2008, 12:22 PM

Maybe if you told us the error... ?
You could try to just copy & paste rather than typing. And what version
of awk has your distro got installed, what distro are you on?

Cheers,

hi thank you for interest

awk -F: '{print $1:$5}' /etc/passwd > passwdless

awk:{print $1:$5}
awk: ^syntax error

Tinkster · 01-19-2008, 12:49 PM

Ooops ... my bad. I forgot to put quotes around the colon
which I wanted to be the separator.

Code:

awk -F: '{print $1":"$5}' /etc/passwd

I'm curious still which version of Linux you're using, because
I haven't seen a password-hash stored in /etc/passwd in a very
long time.

The passwords are stored in an encrypted fashion and cannot be read. If they are not your own passwords you should not have them.

Well ... you asked for the users and their groups. I still don't
understand what you mean by "see passwordless" in this context.
