Call function as different user within the script
Hello

For HP-UX, ksh shell, is it possible to define functions and call them by another user ? For example
Code:
<function_name> ( ) {
command1
command2
}
su - <user> -c <function_name>

Or the only option is defining the user in the function itself as follows -

Code:
<function_name> ( ) {
su - <user> -c command1
}

Please help.

I don't think that's possible. su is going to create another shell. That shell won't have your functions. You can send su a group of commands. I've wrapped several lines of things inside a single su call in startup scripts..

Code:
su - user -c '
    thing1
    thing2 "$@"
' _ "$arg1" "$arg2" # su

be mindful that it's already in single quotes. You can pass arguments too though to help with keeping the quoting manageable.

functions must be defined at the start of every new shell. This can be achievd in ksh by ENV variable pointing to an include file that contains the function.
The perhaps better alternative is
Code:
<function_name> ( ) {
su - <user> -c '
command1
command2
'
}
