Whitespace Issues
Hello forums!

I've been tinkering with a shell script to partition and restore content to a drive based on a type of file in a given directory. My goal is for my script to assemble several restore images, partition the drive based on the images and to then restore those images to the partitions on the drive. Its going to be a multi-boot drive for troubleshooting different systems. Everything is going fine so long as the path to my "configuration" directory does not contain whitespaces.

Here is a snippet:

Code:
for file in `ls "/test folder"/*.ext`; do echo "$file"; done

The result is unusable:

Code:
/test
folder/test1.ext
/test
folder/test2.ext
/test
folder/test3.ext

I've tried single and double quoting all over the place and I can't find the correct usage. All I'm looking for is this:

Code:
/test folder/test1.ext
/test folder/test2.ext
/test folder/test3.ext

The "configuration" folder in my actual script is a variable passed on from another call earlier in the script. I know I could use:
Code:
for file in `ls /test\ folder/*.ext`; do echo "$file"; done

but because the "/test folder" is a variable grepped from the output of a function that only gives human readable output, I'm stuck.


Thanks for any help - I've been working on this line of my script for 3 days now and I can't figure it out. I'm always in awe of how well some folks have mastered the command line. Thanks again!

NAME

       iptables-restore -- Restore IP Tables

       ip6tables-restore -- Restore IPv6 Tables

SYNOPSIS

       iptables-restore [-chntv] [-M modprobe]

       ip6tables-restore [-chntv] [-M modprobe] [-T name]

DESCRIPTION

       iptables-restore and ip6tables-restore are used to restore IP and IPv6 Tables from data specified on STDIN. Use I/O redirection provided by
       your shell to read from a file

       -c, --counters
	      restore the values of all packet and byte counters

       -h, --help
	      Print a short option summary.

       -n, --noflush
	      don't flush the previous contents of the table. If not specified, both commands flush (delete) all previous contents of the  respec-
	      tive table.

       -t, --test
	      Only parse and construct the ruleset, but do not commit it.

       -v, --verbose
	      Print additional debug info during ruleset processing.

       -M, --modprobe modprobe_program
	      Specify  the path to the modprobe program. By default, iptables-restore will inspect /proc/sys/kernel/modprobe to determine the exe-
	      cutable's path.

       -T, --table name
	      Restore only the named table even if the input stream contains other ones.
