i'm willing to provide a small script for you this time, once and explain it as much as i can.
Hopefully we shall see in the future will user lcclaj0 ask simple question again without any tries, but lets assume he is new in scripting and is looking for a simple example.
Code:
INPUTDIR=/directorywithunixfiles
OUTPUTDIR=/directoryforoutput
[ -d $OUTPUTDIR ] || exit 1 # script will exit if $OUTPUTDIR is not a directory.
cd $INPUTDIR || exit 1 # script will exit if it's unable to change directory to $INPUTDIR, additionally it will print the cd command error on stderr
for i in * # for everything in $INPUTDIR
do
if [ -f "$i" ]; then # if it's a file use ux2dos utility on it, otherwise silently ignore.
ux2dos "$i" > "${OUTPUTDIR}"/"$i"
fi
done
cd - # return to directory the script has been issued from.
Directory /directoryforoutput (destination) will contain converted files with /directorywithunix (source) will contain original files, uneffected by operation (exception being modifed atime -access time, if used on filesystem, by default vxfs - yes.)
This is sample shell script with basic error handling.
Shell commands and constructs used :
1. Variable declaration (directories used INPUTDIR OUTPUTDIR)
2. Conditional operator ( || )
3. Test constructs ([ .. ]) # man test
4. for loop to iterate over the directory contents
5. ux2dos utility to convert format.
Script will not go into subdirectories or process files with dots in names e.g .config
Hope that helps.
Best regards
Peasant.
Hi all, so I tried with this script and share it to a directory shared by samba but when I go to open the file on my windows machine the file is still in unix format which is all over the place

libguestfs-make-fixed-appliance(1) Virtualization Support libguestfs-make-fixed-appliance(1)NAME
libguestfs-make-fixed-appliance - Make a "fixed appliance" for libguestfs
SYNOPSIS
libguestfs-make-fixed-appliance [--options] OUTPUTDIR
libguestfs-make-fixed-appliance [--options] --xz
DESCRIPTION
libguestfs-make-fixed-appliance lets you make a pre-built binary appliance for libguestfs.
Note that ordinary users should not need to run this tool.
Some reasons why you might want to use this include:
o You want to make a self-contained libguestfs appliance that can be copied to another machine or platform that doesn't support
supermin(8).
o You have multiple users on the same machine and want to avoid the storage duplication and start-up overhead of having multiple cached
copies of the appliance.
o You want to have very predictable performance from libguestfs (see guestfs-performance(1)).
For deeper understanding of why you might need this tool, read the section "FIXED APPLIANCE" below.
Instead of running this tool, you can download fixed appliances from http://libguestfs.org/download/binaries/appliance/. These appliances
were made using this tool.
There are two ways to use this tool.
o Specify an output directory, for example:
libguestfs-make-fixed-appliance /usr/local/lib/guestfs/appliance
The output directory is created if it does not exist. Four files are created in this directory:
<OUTPUTDIR>/kernel
<OUTPUTDIR>/initrd
<OUTPUTDIR>/root
<OUTPUTDIR>/README.fixed
Note that "OUTPUTDIR/root" is a sparse file, so take care when copying it.
You can then run libguestfs (possibly after copying this directory to another machine) by setting the environment variable
LIBGUESTFS_PATH to "OUTPUTDIR".
o The alternative method is to use the --xz option to create a compressed tarball:
libguestfs-make-fixed-appliance --xz
This creates a tarball in the current directory called:
appliance-<VERSION>.tar.xz
(where "VERSION" is the version of libguestfs). The tarball contains the four files:
appliance/kernel
appliance/initrd
appliance/root
appliance/README.fixed
Note that "appliance/root" is a sparse file, so take care when copying it.
OPTIONS --help
Display short usage information and exit.
-V
--version
Display the version number and exit.
--xz
Instead of creating the appliance in an output directory, create a compressed tarball of the appliance in the current directory called
"appliance-VERSION.tar.xz" where "VERSION" is the version of libguestfs.
Using --xz can take some time. If working normally, the tool is completely silent when it is running.
FIXED APPLIANCE
When libguestfs (or libguestfs tools) are run, they search a path looking for an appliance. The path is built into libguestfs, or can be
set using the "LIBGUESTFS_PATH" environment variable.
Normally a supermin appliance is located on this path (see "SUPERMIN APPLIANCE" in supermin(8)). libguestfs reconstructs this into a full
appliance by running supermin-helper(8).
However, a simpler "fixed appliance" can also be used. libguestfs detects this by looking for a directory on the path containing four
files called "kernel", "initrd", "root" and "README.fixed" (note the "README.fixed" file must be present as well).
If the fixed appliance is found, libguestfs skips supermin entirely and just runs qemu with the kernel, initrd and root disk from the fixed
appliance.
Thus the fixed appliance can be used when a platform or Linux distro does not support supermin. You build the fixed appliance on a
platform that does support supermin, and copy it over, and use that to run libguestfs.
LICENSING
The fixed appliance is a complete Linux binary distro. If you distribute it, you may need to distribute corresponding source files to
remain in legal compliance with the licenses of the software in the appliance (such as the GNU General Public License).
EXIT STATUS
libguestfs-make-fixed-appliance returns 0 if the appliance was built without errors.
ENVIRONMENT VARIABLES
For the full list of environment variables which may affect libguestfs, please see the guestfs(3) manual page.
