WINROOTDIR="C:\\\\"
#Windows root directory. I use it with 'grep' to find the shortcut in the 'strings' command output. It could be a bit more 
#convenient to get rid of that variable and use a more precise 'grep' pattern. In that case, I think the best solution
#is to notice that the first output of "strings [SHORTCUT_NAME].lnk" command will always be the drive letter. Retrieving
#this information in a new variable "IdDrive" and replacing "${WINROOTDIR}" by "${IdDrive}" in the "RelPath" assignment
#line should work. I'll give up to you verify that it is indeed the case ;). The four backslashes are a annoyance but
#we have to escape one backslash for 'grep' and one for the path itself. Maybe there is some way to tell grep not to
#interpret those backslashes from the script.

#echo ${WINROOTDIR}

WINMOUNTPOINT="/mnt/win/"
#Linux absolute path where I have mount my Windows partition.

RelPath=`strings "$1" | grep ${WINROOTDIR}[A-Za-z] | tr -d ${WINROOTDIR}`
#Here's where all the work is done. The command 'strings' with argument a Windows .lnk file will display some text 
#filtered by 'grep' to keep just the Windows absolute path. After that, 'tr' delete the Windows drive letter.

#echo ${RelPath}

PathFromLinux="${WINMOUNTPOINT}${RelPath}"
#We finally append the relative path of the directory pointed by the shortcut to the absolute path of the Windows
#partition mount point.

#echo "Moving to ${PathFromLinux}"
