suppose if we issue edquota -u <username>,a window opens and we can set there the soft and hard limits for the user.
but, where does the quota information comes from i.e from which file the edquota is retrieving the information
and
how to set quota for a user from shellscript

pls tell me how to excute mail command in shell script
i had given mail -s "hello raj" raj in shell,
where raj is username
but when i execute that script cursor is wainting for input until i press cntrl+d
But i have to send mail to a user in a shellscript not from the prompt

If i issue a write command at prompt
i am getting the error
write: you have write permission turned off.
even though i am trying this in root i am getting this error and i have seen in /etc/bin/write. the executable permission is given for this.
pls reply this

i want to issue a message such as "Contact System Admin" for a particular user whenever that particular user logs in and the user work must be suspended i.e the user must not be allowed to do any thing.
so can u tell how this can be acheived.

can u tell how to find the number of users and their login names from root.
suppose if i issue ls /home. it is listing some other names such as lost+found, quota.user, quota.group etc along with the user names.
so can u tell how to find exactly the no of users in the system and their login names

I don't want to do anti social things.
I am doing a project for system administrator. I want to issue a message to a user like
"Contact system administrator and i want to suspend the user from work until he contacts system admin"
so tell me how to issue a message immediately when ever the user logins
and he should not be allowed to enter to his login. or suppose if he already login, a message should come and the work must be suspended.
thanks in advance

hello Mr Richard Klein
Thanks for ur quick reply.
I had already tried what u said useradd -p option. no error is shown in that
but when we login with the user created with useradd -p it is not allowing to login.
but when we entered as root and tried to create useradd with the username above it is showing that user already exists
that means though we give the command useradd -p it is creating the new user but not assigning the password
pls reply this soon
thanks in advance

The problem is to create a new user and assign a password for that user from the shell script instead of at prompt.
i have create a file using vi editor
and i have typed
useradd xyz
passwd xyz pqr
and when i run the shell by giving bash file name, the new user is created but the password is not assigned. it is treating pqr is also a username
please tell me how to assign password for a user from the shell script
