Hi David,

no that's not really the case since strings containing those escape
literals are transformed by Python as raw strings with another leading
backslash to distinguish them between real control characters in a
stream.
Every Python standard distribution actually comes with a standard
script for this.
It's
<code>
#! /usr/bin/env python
"Replace CRLF with LF in argument files. Print names of changed files."
import sys, os
def main():
for filename in sys.argv[1:]:
if os.path.isdir(filename):
print filename, "Directory!"
continue
data = open(filename, "rb").read()
if '\0' in data:
print filename, "Binary!"
continue
newdata = data.replace("\r\n", "\n")
if newdata != data:
print filename
f = open(filename, "wb")
f.write(newdata)
f.close()
if __name__ == '__main__':
main()
</code>
and can be used from the shell by passing the file names as arguments.
However, I am not absolutely sure if there are some situations where
there really would be some conflict.
