要查找文件中的特定的行末标志比如

能否用regular expression来查找，就向word中的^p一样

1. which grep are you using? You should use GNU grep or egrep.
2. make sure your lines do not end with '\r\n' like most files

hmm, I don't think that egrep can do that either. It buffers

I use AIX 4.3
both grep and egrep give me the first line of the file when
i use
?grep '\n' myfile
but can't find all of the lines,also,the specified line I
am searching
sed even dosen't accept '\n':(

No idea. GNU grep works for me on both Linux and Solaris.
