Subject: How to get bash to shut up about SIGPIPE?
Message-ID: <Pine.LNX.4.58.0504281121430.18901@ppc970.osdl.org>


Right now my major gripe with cogito is "cg-log" (which is actually the 
only command I use right now, everything else I just do by hand with the 
raw git archive) is that bash is being an ass about SIGPIPE, and when I 
only look at the top part of the log, ie I do something like:

	torvalds@ppc970:~/src/cogito> git log | head

it spews out the ten first lines of the log, and then it spews about a 
million lines (well, 20, but anyway) of crap:

	/home/torvalds/bin/cg-log: line 87:  6338 Done                    echo -n $color$key $rest
	      6339 Broken pipe             | sed "s/>.*/> ${pdate/+0000/$tz}/"
	/home/torvalds/bin/cg-log: line 87:  6328 Done                    cat-file commit $commit
	      6329 Broken pipe             | while read key rest; do
	    case "$key" in 
	        "author" | "committer")
	            if [ "$key" = "author" ]; then
	                color="$colauthor";
	            else
	                color="$colcommitter";
	            fi; date=(${rest#*> }); sec=${date[0]}; tz=${date[1]}; dtz=${tz/+/}; lsec=$(expr $dtz / 100 \* 3600 + $dtz % 100 \* 60 + $sec); pdate="$(date -Rud "1970-01-01 UTC + $lsec sec" 2>/dev/null)"; if [ "$pdate" ]; then
	                echo -n $color$key $rest | sed "s/>.*/> ${pdate/+0000/$tz}/"; echo $coldefault;
	            else
	                echo $color$key $rest $coldefault;
	            fi
	        ;;
	        "")
	            echo; sed -re '
	                                        / 
	*Signed-off-by:.*/Is//'$colsignoff'&'$coldefault'/
	                                        s/./    &/
	                                '
	        ;;
	        *)
	            echo $colheader$key $rest $coldefault
	        ;;
	    esac;
	done

which is just incredibly annoying, since it makes the ten lines I actually 
_wanted_ to get scroll off the screen..

Damn bash. What's the magic incantation that says SHUT UP!?
