Here's my python fix for that moronic problem (moronic of Dos designers, who
thought that two characters per line ending were a good idea when there
already was a perfectly viable convention to follow, namely that of Unix.
Perhaps they were following a VMS convention or somesuch, I don't know).
Call this tounix.py, put in your path and use as needed even on a whole
directory ("tounix.py *" will work):
[python]> cat tounix.py
"""Convert DOS or Macintosh text files to unix end-of-line convention.
tounix file1 file2 ...
A backup (file1~,file2~,etc.) of each file is made.
files = sys.argv[1:]
if len(files) == 0:
for file in files:
original = open(file).read()
bak = file+'~'
new = open(file,'w')
PS. This is quick and dirty but works. If you want, you can spice it up with
lots of error checks and whatnot.
