+#USAGE
+#	fontd CHAR DIR
+#		display CHAR if found in any bdf fonts in DIR/
+
+#gets font size, it can take multiple fonts as input so only get the first one
+#and assume they're all the same size
+size=$(cat $2/*bdf | grep -m 1 PIXEL_SIZE | awk '{print $2}')
+
+#get bdf bitmap info from bdf
+#fflag ensures only one result even with multiple bdfs, cflag finds the char,
+#bflag labels just the bitmap part
+bdf=$(cat $2/*bdf | awk "NR==1{fflag=0}/STARTCHAR $1$/{if(fflag==0){cflag=1;fflag=1}}/BITMAP/{if (cflag==1){bflag=1};next}/ENDCHAR/{cflag=0;bflag=0}bflag")
