In my Bash-script i have to handle filenames with spaces. These are the important lines inside my script:

mp3file="/media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\ Vol.5\ \[MP3PRO\]/01\ -\ Nofx\ -\ Pump\ up\ the\ Valium.mp3"
echo "Command: mp3info -x `echo $mp3file`"
mp3info -x `echo $mp3file`

Unfortunately, the command does not work, because the filename is splitted:

mp3info: invalid option -- '\'
mp3info: invalid option -- '\'
Error opening MP3: /media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\: No such file or directory
Error opening MP3: Vol.5\: No such file or directory
Error opening MP3: \[MP3PRO\]/01\: No such file or directory
Error opening MP3: Nofx\: No such file or directory
Error opening MP3: Pump\: No such file or directory
Error opening MP3: up\: No such file or directory
Error opening MP3: the\: No such file or directory
Error opening MP3: Valium.mp3: No such file or directory

I also tried to add a custom IFS as i read on some forums:

SAVEIFS=$IFS
IFS=$(echo -en "\n\b")
# Script like above
IFS=$SAVEIFS

But this way, i'm getting the error

Error opening MP3: /media/d/Music/zz_Hardcore/Sampler/Punk-O-Rama\ Vol.5\ \[MP3PRO\]/01\ -\ Nofx\ -\ Pump\ up\ the\ Valium.mp3: No such file or directory

I tried quite a while now but i cannot get my script to work. What is strange is that if i'm running the same command that my script should create manually (echoing it inside my script) on the Shell, it actually works. But not inside my script. Any hints?
