I don't think that you can do that through a command. May be something like this?
Code:
# cat test.sh
#!/usr/bin/ksh

func1() {
        echo global function
        echo $(ps -ef |awk -v pid=$$ '{if($2==pid) print $NF}') has run func1
}

Code:
# cat test1.sh
#!/usr/bin/ksh

. ./test.sh
echo $0 is running
func1
echo $0 is ending

Code:
# ./test1.sh
./test1.sh is running
global function
./test1.sh has run func1
./test1.sh is ending

Here test.sh holds the global function, test1.sh 'sources' test.sh via the '. ./' mechanism.

Note: on Solaris, please use nawk instead of awk.
