[Fwd: problem with the tr command] SOLVED

[George Herson]

Please ignore the question i sent last hour.  It was just the usual
shell confusion: i needed quotes around \r and \n:

# cat /tmp/junk.b2 | tr '\r' '\n' >/tmp/junk.b3
# cmp -c /tmp/junk.b2 /tmp/junk.b3
/tmp/junk.b2 /tmp/junk.b3 differ: char 12, line 1 is  15 ^M  12 ^J
