Folks;
First about find:
when i run this:
find . -name '*log*' -mtime +10 -print | sed 's+^\./++;s+/.*++' | sort -u

i got list of log files but also get a directories (although directory names doesn't have "log" in it).
How can i exclude the directory from the output of this find command?

Now for grep:

How can i grep for some file names & exclude some other files, for example:
Let's say my files named file.now.txt and i want to grep for files named *.txt except for the ones with now.txt
any idea?
