How to pass values in one script from another script?
Hi,
I am trying to make a script A which will install the build automatically.
At one point in this script it will call another script B.
This Another script B will have options like
1) go to main manu
2) Install package
3) Uninstall package
4) Exit

Now for installation purpose I have 4 packages to install and while pressing Key 2 I need to give a full path of that package...

So, my question here is when my script A will reach to point where script B will start how can I supply this key like 2 and different paths for package... So that script B will automatically completed.

Please let me know if you dont understand my issue.

What is the point writing 2 scripts?
Or did I miss something?

If I understood your problem, just pass the variables as arguments to script B:
Code:
# Script A calling script B:
key=2
packagePath="<PathToPackage>"
<PathToScriptB>/scriptB.sh "${key}" "${packagePath}"

# Script B parsing arguments:
key="${1}"
packagePath="${2}"


Is this what you are looking for?

Your question is valid... But Actually I am from Testing team and Script B is runniing since ages so I dont want to touch script B.

I want to do something like by which instead of punching keys from my keyboard script A will automatically pass the values to script B.

Maybe write the variables and values to a configuration file and load it by using one line in script B.

Code:
# Script A will write a file like:
# cat ./scriptB.cfg 
key=2
packagePath="<PathToPackage>"

# In scriptB, just add the following line:
. ./scriptB.cfg

Don't forget that the variables must have the same name!

hhhmmmm felipe... I can try for the second option you suggested.
But I'm bit confused... I mean what we have to specify in config file
i.e.

Script A:
{Few other commands}
{sh script B}

Script B:
{Options and awk script and Blah blah}

config.file:
??

Not exactly!

You will need to write the variables you want to overwrite in script B in a config file.
Code:
# Write the variables you want to overwrite in script B to the config file from script A
############
# In script A
############
scriptBConfigFile="<PathToConfigFile>/scriptB.cfg"
echo "key=2" > "${scriptBConfigFile}"
echo "packagePath=<PathToPackage>" >> "${scriptBConfigFile}"
############

############
# In script B
############
scriptBConfigFile="<PathToConfigFile>/scriptB.cfg"

. "${scriptBConfigFile}"

Is it clear now?

If it is not, check the "source" command man page or check this link: source or dot operator MAN Page
