Re: [Bug-ddrescue] Cannot handle "$" in the filename for destination or logfile

[Matthew Ruffalo]

Hi Scott-

This is not ddrescue behavior; this is your shell (presumably bash) 
expanding $MFT into the (empty) contents of the variable named MFT. 
ddrescue is dutifully writing to exactly the file name that it is given.

To prevent this variable expansion, use single quotes:

$ echo "inode_0_$MFT"
inode_0_
$ echo 'inode_0_$MFT'
inode_0_$MFT

MMR...
