Hi all,
I'm trying to pipe of output of a command through egrep.
If I do this
ldconfig -p | egrep "libstdc++"
libstdc++.so.6 (libc6,x86-64) => /usr/lib64/libstdc++.so.6
libstdc++.so.6 (libc6) => /usr/lib/libstdc++.so.6
that *IS* the answer I expect.
But if I simply add a ".so" to the egrep target, it returns nothing
ldconfig -p | egrep "libstdc++.so"
(empty)
If I *escape* the two "+", it works again.
ldconfig -p | egrep "libstdc\+\+.so"
libstdc++.so.6 (libc6,x86-64) => /usr/lib64/libstdc++.so.6
libstdc++.so.6 (libc6) => /usr/lib/libstdc++.so.6
Why do I need to escape the "+" in the last case, but not in the first?
Terry
