Source functions from variable
so i found a way to do this.

Code:
#!/bin/bash
MYF=$(/home/jason/myfunctions)
source <(printf '%s\n' "${MYF}")
echo "${var1}"

/home/jason/myfunctions is a script that outputs information..i.e. functions...etc that needs to be sourced. I have no control over /home/jason/myfunctions. i can only run it.

the above works for me. as im able to source the output of the myfunctions script. however, the above solution is not portable. it only seems to work on newer versions of bash.

can anyone look at the above solution and come up with a modified version of it that will work everywhere on all unix systems?

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).

FILES

       /etc/shells	       lists shells on system
