Hello everyone,
I have a very strange problem using sed. I'm trying to parse a normal
text file and one of the things i want to do is remove all lines that
contain an arrow (looking like that ->). So I do
sed -e '/\-\>/ d' infile > outfile
which works perfectly fine on my Mac running Mac OS X 10.4.10 but
doesn't do anything under Linux (tried it with both openSuse 10.2 and
Scientific Linux SLC 4.4). On the linux machines it's GNU sed v4.1.2.
I also tried substituting the arrow, which again didn't do anything,
so quite obviously the pattern is not found. Is this due to some
discrepancy between the linux and the BSD versions of sed, or some
special character differences that I'm not aware of?
And does anyone have a suggestion how else to achieve the deletion of
the lines under Linux?

Thanks & Cheers,
Michael
