Expanding a little bit on what Jim already said...

It is ALWAYS a good idea to tell us what shell and operating system you're using when you ask a questions like this! The way to do this varies from shell to shell. Assuming that you are using a shell that is based on Bourne shell or POSIX shell syntax, that the functions file only defines functions and/or variables that your script will want, that the functions file does not invoke any commands or functions that you don't want your script to execute, and that the function definitions are suitable for the shell that will be running your script; you bring those functions into your script by dotting the function file before you reference any of the functions you want to invoke from that function file.

If you only want to reference those functions in the subshell environment that is set up to run the 1st command substitution in otherscript.sh, you could change the 1st line you showed us in that file from:

Code:

results=$(/var/home/functions.sh ; myTest ; myCar)

to:

Code:

results=$(. /var/home/functions.sh ; myTest ; myCar)

If you want to reference those functions in other places in otherscript.sh including inside and/or outside any other subshells it starts, dot your function file before you invoke any subshells:

Code:

. /var/home/functions.sh
results=$( myTest ; myCar)
MYPWD=$(echo "${results}" | egrep MYPWD | awk -F"=" '{print $2}')
MYLOGNAME=$(echo "${results}" | egrep MYLOGNAME | awk -F"=" '{print $2}')
MYDATE=$(echo "${results}" | egrep MYDATE | awk -F"=" '{print $2}')
MYUPTIME=$(echo "${results}" | egrep MYUPTIME | awk -F"=" '{print $2}')
