Hi,

I am using hostname environment variable in my shell script to print the host name but it's printing nothing.Can you please help me on this.

Please find the part of the code pasted here:

llist=
llist=$(ps -ef | grep -v grep | grep -c "$1")

echo "Hostname is ${hostname}"

From where do you want to extract this hostname value ? You can use simple : localHostName=`hostname`; echo $localHostName

1. assign the return value to a variable
2. send (echo) the variable to screen

Hi,

When I am using commnad:hostname in unix command prompt , it's printing the system name of my system but when I use this command in shell script it gives nothing.

localHostName=hostname
echo $localHostname

Try as I show below (ignoring the > as the prompt character):

Also u can use the environment variable HOSTNAME.

Hi,
U can use the environment variable HOSTNAME or
the command hostname <With options such as -a>
