It is LOGNAME not logname.

To find environment variable list then,

# env

will give it.

As per man page of logname, logname commands gets the login name using getlogin call, which in turns checks it in /etc/utmpx.

May be that file is corrected. Create anew one and check. (Back up old one, in case required)

"logname" is a binary and usually called in /etc/profile or .profile. it is setting the variable LOGNAME to the user name.
find the binary by typing
whereis logname
and you will get
/usr/bin/logname
the profiles are executed while you logging in and within the profiles are some commands to set various variables.
try
man logname
for more information.

Hi

There is no variable called logname in my login path also!!!!!

That means u have customized the /etc/profile or /$home/profile file to add an entry called logname. The command assigned to that variable is not working properly.

If u r getting this error for all users check the /etc/profile file and search for the string logname.

If u r getting this error only for ur loging name then open /home//.profile file and search for the string logname.

Most probably the problem will come for the variable PS1 in ur profile file. Proper command sustitution may not have done for that variable.

RAC is caught the correct thing. LOGNAME is a environement variable and logname is a binary to get current users user name. Try to execute it with command line as,

# logname
Is it working?

# ls -l /usr/bin/logname
-r-xr-xr-x 1 bin bin 12288 Nov 14 2000 /usr/bin/logname

May be you can get logname information as,

# who -mu | awk '{ print $1 }'

Or else,

write c coding to get logname or copy the binary from other hp-ux machine with same version.

hth.

i copied the good binary from some other server and i copied in to /usr/bin with proper permissions. then also that binary is no working..

it is possible that the /etc/utmp or /etc/utmpx file is corrupt.
