how to find out the home directory of a user??

Hi all,
I would like to know how to find out the home directory of a particular user..
If am the root , then my Home directory will be /
if say am just a user logging into the terminal then my home dir would change,
so accordingly i would like to know how to find it out...

I know that the shell prompt changes accordingly but how to figure it out through a command?, I mean is there any command to find out the home directory of a particular user(be it the root or an average joe!!!)

there are many ways....

$ cd
$ pwd

$ echo $HOME

$ grep username /etc/passwd

I forgot to mention, i would like to know how to incorporate it into a script..
I mean how to give input to $HOME so that depending upon the username the $HOME gives me the home dir...

I must also mention, i will not be running as root...

One approach


>cat /etc/passwd | grep "$find_user" | cut -c":" -f6

awk only
awk -F: -v v="user" '{if ($1==v) print $6}' /etc/passwd

how do you authenticate your users? local files, ldap or nis? if local files, give an exampel of your "/etc/passwd".

on solaris works something like this:

# grep username /etc/passwd | cut -d ":" -f6

I dont think awk and all will be necessary,(its for some ppl who dont know about awk )
Not yet taught ,i suppose!!!!(so will have to make do with "if and else" only....

ive just written this pls have a look!!!

for i in $*
cat /etc/passwd |grep $i | cut -d ":" -f 6

Here how to i specify a constraint stating that if no arg is passed it should return an error?
I tried with simple ,
if test -z $i ; then
echo "error"

how do i get something like this working?
