Script Execution Help Needed

pinga123 · #1 (**permalink**) 3 Weeks Ago

Hi guys i have a script (takeconsole) as following
I have moved it to /usr/local/bin to make the execution of script simpler.
below are the content of the file.

When i run the file by typing "takeconsole" .it always ask for entering the IP address but when i run it by using ". takeconsole". it ask for entering the IP address only at first occurrence.

How can establish 2 scenario by just typing "takeconsole" and not ". takeconsole".

Code:

if [ -z "$DISPLAY" ]
then
echo "Please Enter IP address of your machine"
read ipadd
export DISPLAY="$ipadd:0.0"
else
echo display is already set
fi

When you run the file with ". takeconsole" , the DISPLAY value is set and the next execution have already the previous value.

With ".", the current shell get the values of the "takeconsole" run (the value is exported).

I just want to make the execution simpler how would i establish . takeconsole by just typing takeconsole.

And ..... can you do a function in .profile file with that code ???

Code:

User Home .profile:
function takeconsole {
   if [ -z "$DISPLAY" ]
   then
      echo "Please Enter IP address of your machine"
      read ipadd
      export DISPLAY="$ipadd:0.0"
    else
      echo display is already set
    fi
}

And then:

    $ takeconsole

i dont have much information about .profile and function in .profile .
will it set the DISPLAY globally?

The value will be set when the user call to 'takeconsole' function from the prompt such as other script.

ok?
