Assigning the output of a command to a variable, where there may be >1 line returned?
Hello
I am using unix CLI commands for the Synergy CM software. The command basically searches for a folder ID and returns the names of the projects the folder sits in. The result is assigned to a variable:
When the command only returns one line of output, there is no problem.
However, if the folder is contained in more than one project, the command will return more results, such as the following:
agriculture-stst
agriculture-uat
My question is, when assigning the output of a command to a variable, where there is more than one line returned by the command, what will be assigned to the variable?
- Will it pick up the first line only?
- Will it pick up the last line only?
- Or does it get confused and pick up nothing at all?

Thanks quirkasaurus, though I'm not entirely sure if that's what I'm wanting.
For each result returned by FIND_USE=`ccm folder -fu -u -f "%name"-"%version" ${FOLDER_ID}` I need to be able to perform a command upon.
i.e. I want to run a command which will use agriculture-stst as a variable and then run again and use agriulture-uat (and again if there has been anything else returned by the initial FIND_USE= ...
Am I needing to use some sort of "while" loop? I'm a bit of novice at this still..
You have an array. Each element is "one answer" you got back.
I don't understand what you want to do with the results but this is how to reference array elements, I changed the variable name of the array to "myarray"

I'm converting decimal to integer with bc, and I'd like to assign the integer output from bc to a variable 'val'.
