cpmtools allows you to access CP/M file systems.  Currently it contains:

cpmls - list sorted directory with output similar to ls, DIR, P2DOS DIR and
  CP/M3 DIR[FULL]
cpmcp - copy files from and to CP/M file systems
cpmrm - erase files from CP/M file systems
cpmchmod - change file permissions
cpmchattr - change file attributes
mkfs.cpm - make a CP/M file system
fsck.cpm - check and repair a CP/M file system (only simple errors can be
  repaired so far)
fsed.cpm - view CP/M file system
manual pages for everything including the CP/M file system format

All CP/M file system features are supported. Password protection is ignored,
because passwords are easy to decrypt, but a pseudo file [passwd] contains them,
if you are curious what your old password was. The disk label is read as
special file [label]. User numbers are specified as user:file.
