How to backup a folder & exclude all images

The code below will first create a file called Exclude containing the paths to all common document files I wish to exclude from my backup, images, documents etc.

Secondly the tar command will be used to create a compressed tgz containing everything in the given folder and recursive folders excluding the files as detected.

  find ./folderIwantBackingUp/ ! -type d -print | egrep ‘/,|%$|~$|\.old$|\.mpg$|\.zip$|\.wmv$|\.mp3$|\.MP3$|\.mp4$|\.MP4$|\.av2$|\.ppt$|\.dir$|\.pps$|\.qt$|SCCS|/core$|\.o$|\.orig$|\.mpeg$|\.mov$|\.doc$|\.xls$|\.pdf$|\.swf$|\.fla$|\.wav$|\.aif$|\.aiff$|\.mp3$|\.jpg$|\.JPG$|\.jpeg$|\.JPEG$|\.gif$|\.GIF$|\.png$|\.PNG$|\.psd$|\.PSD$|\.tar.gz$|\.tgz$|\.TGZ$|\.tif$|\.TIF$|\.tiff$|\.TIFF$|\.tga$|\.TGA$|\.ram$|\.rm$|\.rma$|\.psd$|\.PSD$|\.ai$|\.AI$’ > Exclude tar czfX ~/myBackup.tgz Exclude ./folderIwantBackingUp/
