Always test before posting. Even a one liner. That doesn't work, or at
least NFM:
[EMAIL PROTECTED] /test/grep-test> od -c test.dos.txt
0000000 H e l l o w o r l d \r \n
0000015
[EMAIL PROTECTED] /test/grep-test> od -c test.unix.txt
0000000 H e l l o w o r l d \n
0000014
[EMAIL PROTECTED] /test/grep-test> grep -E 'ld^M?$' *
[EMAIL PROTECTED] /test/grep-test> grep -E 'd^M?$' *
[EMAIL PROTECTED] /test/grep-test> grep -E '.^M?$' *
[EMAIL PROTECTED] /test/grep-test>
Grep knows there's a char there, but it won't match it with ^M.
[EMAIL PROTECTED] /test/grep-test> grep -E '.$' *
test.dos.txt:Hello world
test.unix.txt:Hello world
[EMAIL PROTECTED] /test/grep-test> grep -E 'd.$' *
test.dos.txt:Hello world
[EMAIL PROTECTED] /test/grep-test> grep -E 'd^M$' *
[EMAIL PROTECTED] /test/grep-test> grep -E 'd^m$' *
[EMAIL PROTECTED] /test/grep-test>
What makes you think grep understands ^ notation to indicate control
chars? It doesn't say so in the info page. (It doesn't recognize [\r]
either.)
Actually, it seems that grep
