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!

extundelete

EXTUNDELETE(1)						      General Commands Manual						    EXTUNDELETE(1)

NAME

       extundelete - utility to undelete files from an ext3 or ext4 partition.

SYNOPSIS

       extundelete [options] device-file...

DESCRIPTION

       extundelete is a utility that can recover deleted files from an ext3 or ext4 partition
       extundelete uses the information stored in the partition's journal to attempt to recover a file that has been deleted from the partition.
       There  is  no  guarantee  that any particular file will be able to be undeleted, so always try to have a good backup system in place, or at
       least put one in place after recovering your files!

OPTIONS

       --version
	      Prints the version number of extundelete.

       --help Print a brief usage summary for extundelete.

       Partition name
	      Name of the partition that has deleted files, such as /dev/sda3.
	      Could also be the file name of a copy of the partition, such as that made with dd.

       --superblock
	      Prints information about the filesystem from the superblock.

       --journal --superblock
	      Prints information about the journal from the journal's superblock.

       --inode #
	      Prints the information from the inode number of the filesystem given, such as "--inode 2".

       --block #
	      Prints the contents of the block, called as "--block 9652".

       --restore-file path/to/deleted/file
	      Attempts to restore the file which was deleted at the given filename, called as "--restore-file dirname/filename".

       --restore-inode #
	      Used to restore inodes by number, called as "--restore-inode 2569".
	      Also accepts a list of inodes separated by only commas, such as "--restore-inode 2569,5692,6925".

       --restore-files filename
	      Restores a list of files. First, construct a list of files in the same style as would be
	      used in the --restore-file option, and save it to the file "filename".
	      Then, this option may be used to attempt to restore those files with a single call to extundelete.
	      This form also reduces redundancy from multiple calls parsing the journal multiple times.

       --output-dir path/to/dump/recovered/files
	      Restores files in the output dir 'path'.
	      By default the restored files are created under current directory 'RECOVERED_FILES'

       --restore-all
	      Restores all files possible to undelete to their names before deletion, when possible.  Other files are restored to a filename  like
	      "file.NNNN".

       --restore-directory path/of/directory
	      Restores all files possible to link to specified directory to their names before deletion, when possible.

       -j journal_dev
	      Specifies the device that is the external journal of the file system.

       -b block_number
	      Specifies the block number of the backup superblock to be used when opening the file system.

       -B block_size
	      Specifies the block size of the partition to be used when opening the file system.

       --before date
	      Only  restore  files  deleted  before the date specified, which should be in the form of the number of seconds since the UNIX epoch.
	      Use a shell command like
	      $ date -d "Aug 1 9:02" +%s
	      to convert a human-readable date to the proper format. The conversion from the number of seconds to a readable format may  be  found
	      by using either of the following:
	      $ date -d@1234567890
	      $ perl -le "print scalar localtime 1234567890"

       --after date
	      Only restore files deleted after the date specified, which should be in the form of the number of seconds since the UNIX epoch.
	      See the notes for the --before option for more information.
