seismic software,very useful

#! /bin/sh
# bigfiles - show large files in current tree
# Usage: bigfiles [size]
# Jack K. Cohen, 1988
#
# Note: all this damn ___MARKER_FILE stuff is because if find comes up
#      ls will list everything in the current directory!
#      /etc/skulker on PS/2 might show a better way.
