How to modify BASEDIR with request script?

UNIX for Advanced & Expert Users

Here is request script:

#!/bin/sh
echo "Current install root path is [ $BASEDIR ]"
CONFIRM="n"
while [ "$CONFIRM" != "y" ]
do
        BASEDIR=""
        while true
        do
           echo please input install root path then press [ENTER]:
           read BASEDIR
           if [ ! -d "$BASEDIR" ]
           then
                 echo "$BASEDIR is not a valid path"
           else
              break
           fi
        done
        echo "Are you sure to change install root path to [ $BASEDIR ]? (y/n)"
        read CONFIRM
done
cat >$1 <<!
BASEDIR='$BASEDIR'
!
echo "Install root path is set to [ $BASEDIR ]"
exit 0

The request script is invoked and "BASEDIR" is set correctly. It can also be seen in postinstall script.

The problem is, the package is still installed to the default BASEDIR - "/" rather than the above one. :confused:

Any help will be appreciated! :cool:

What kind of package? What operating system? What is the '$1' that this script is writing the output to?

3

It's Solaris package.

$1 is an implicit parameter passed into request script.

4

So... how is the Solaris pkgadd command going to know where you have set this new BASEDIR value? Are you passing it as a parameter on the pkgadd command-line somehow?

5

Noop....basically that's how UNIX works, you never know what's going on behind the scene.

BASEDIR is a default environment variable. It represents where the root install path, based on Sun document and my understanding.

6

Well, if that's the case, how are you setting the environment variable? The script above just stores its value in the file specified by $1.

Problem solved.

In file prototype, the path must be relative path rather than absolute path.

/path-1/path-2/... (x)

path-1/path-2/... (v)
