|& is useful in these cases, as it redirects both stdout and stderr to the piped process's stdin. It's a cshism, but it works in both zsh and modern bash. Much nicer than typing cmd 2>&1 | cmd. For context try grep -2, where 2 is the desired lines of context. $ wget --help |& grep -2 base -i, --input-file=FILE download URLs found in local or external FILE -F, --force-html treat input file as HTML -B, --base=URL resolves HTML input-file links (-i -F) relative to URL --config=FILE specify config file to use -- existing files (overwriting them) -c, --continue resume getting a partially-downloaded file --start-pos=OFFSET start downloading from zero-based position OFFSET --progress=TYPE select progress gauge type --show-progress display the progress bar in any verbosity mode (Not that I'm arguing that this is an excuse for wget's [and GNU projects' in general] man pages sucking, but it's a useful workaround.)
