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:
Code:
FIND_USE=`ccm folder -fu -u -f "%name"-"%version" ${FOLDER_ID}`

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?

Many thanks
Glyn

next(1mh)																 next(1mh)

Name
       next - show the next message

Syntax
       next [ +foldername ] [ -[no]header ] [ -help ] [ -showproc program ] [ -noshowproc ] [ options to ]

Description
       The  command  displays  the  next message in the current folder.  The next message is the one after the current message in the folder.  The
       message that is shown becomes the current message.

       If you name a folder using the +folder argument, displays the next message in the folder you specify.   That  folder  becomes  the  current
       folder.

Options
       -header
       -noheader Displays  a  one-line	header before the message.  The header consists of the name of the folder and the message number.  This is
		 the default behavior.	It can be suppressed with the -noheader option.

       -help	 Prints a list of the valid options to this command.

       -showproc program [ options ]
       -noshowproc
		 Specifies an alternative program to list messages.  The default is to use the program defined by the showproc: entry in the file.
		 As with you can give options to the program at the command line.  These are passed directly to by

       The defaults for this command are:

	      +folder defaults to the current folder
	      -header

Restrictions
       The  command  is  really  a  link  to  the program.  As a result, if you make a link to and that link is not called your link will act like
       instead.  To avoid this, add a profile-entry for the link to your and add the argument to the entry.

Profile Components
       Path:	   To determine the user's Mail directory
       showproc:   Program to show the message

Files
       The user profile.
