[linux-help] Regular expression with grep
[Top] [All Lists]

I have a large file which is a concatination and sort of two files, one
from msdos and the other from linux. Each line is a single word. grep
doesn't work as I expected on this file. Examination revealed some
lines end with "(space)LF" and some end with "CR/LF".
I want to eliminate the CR and the space. I tried
cat foo |sed s/\x0d\x0a/\x0a/ and it didn't do anything. A test run of
cat foo |grep \x0d finds nothing. Neither does
cat foo |grep \x61. cat foo |grep a finds lots of words with an "a" in
I tried many combinations of quotes, parentheses, braces, brackets,
single quotes and nothing works with grep or sed.
Several books and a search of the web didn't turn up anything useful.
