[TriLUG] recovering files from lost+found

[Charles Mangin]

thanks for the pointer. with a little fiddling and some more googling,  
i came up with a workable script:



files=/shmoo/lost+found/*
for f in $files
	do file "$f" |
	grep "JPEG image data" |
	awk -F: '{ printf("mv %s %s\n", $1, $1".jpg") | "sh"}'
done


this is renaming all the random l+f files that are jpegs. with minor  
tweaks, i should be able to find all my M4A and M4P files and recover  
them.
