This is my go to find command. It searches for files and directories with partial matches of the first parameter.
# f - everyday find
# usage:
# f filename_fragment [path]
# skips whatever you list in _exclude_matches
_exclude_matches=(bundle .git *.pyc)
_excludes=''
for _match in $_exclude_matches; do
_excludes="${_excludes}-name '$_match' -prune -o "
