# From: c2a192@ugrad.cs.ubc.ca (Kazimir Kylheku)
# Newsgroups: comp.unix.shell,comp.os.linux.misc
# Subject: GNU Bash Script to fix filenames
# Date: 28 Mar 1996 14:54:43 -0800
# Organization: Computer Science, University of B.C., Vancouver, B.C., Canada
#
#This is a script which takes a list of directories, descends through each one
#and ``corrects'' filenames that:
#
# - contain filename globbing characters: * ? [ ]
# - quote characters: ' "
# - control characters: 0-31 (127 is not dealt with---oops)
# - - or + as the first character
#
# The GNU version of 'tr' is required. Also requires 'sed'.
#
# Script to process a given list of directories recursively
# and rename each file to something that is reasonable.
#
# The rules are:
#
# 1. replace each space, [, ], *, ", and ' character in the name with a
# period.
# 2. replace each control character 1..31 with a printable character obtained
# by adding 64 to the ascii value. ^A becomes A, ^B becomes B and so on.
# 3. replace a - or + occuring at the beginning of the name with a #
#
# 4. if the resulting name has been changed in any way, then
# 5. if a file of the new name already exists, then
# 6. add a . to the new name and goto step 5.
# 7. rename the old name to the new name
#
# written by Kaz Kylheku <kaz@cafe.net>
# March 1996
# Vancouver, Canada
#
# requires GNU 'bash', GNU 'tr', and some sort of 'sed' program.
