Your variable assignment is wrong, it should be:

Var='/etc/sysconfig/..'

No spaces around =.

If you want to send in a environment variable for one script only then you can use:

Var='/etc/sysconfig/..' ./my_script.sh

And inside my_script.sh:

printf "%s\n" "$Var"
# Will print /etc/sysconfig/..

If you want to send arguments to my_script.sh do what @JohnZwinck suggested. What I suggested is only to change environment variable and shouldn't be abused to send/receive regular variables to a command.

Do this:

Var='/etc/sysconfig/..'
bash script1.sh "$Var"

Then in script1.sh:

Var=$1
cat "$Var"

The quotes around "$Var" are required to support paths containing spaces.
