Hi Gurus,

Iam new to Unix.  
I had a requirement where i should use a file for example  
Host.sh or Host.txt  
Host = 555.254.45.14  
username = aaaa  
pwd = SSSSSS123

And this file need to be used in different scripts.  
For example i have script1.sh

where i want to use the values of Host,username & pwd to connect

and similarly in other scripts like script2.sh and script3.sh

So, please provide any example scripts or other info

if you export them, any child script will see them.

Otherwise pass as command line arguments.
