Escaping backslash and asterisk in egrep to match "\*"
So far what i've got is
Code:
egrep '^(\\)\*$'

No luck.

I've searched the web and not much luck. I know about the escape character
Code:
\

but its confusing to figure out how to use it to match a backslash and use it to escape the asterisk also. Any ides? Thanks!
