Zensiert mein Freund grep:

Code: Alles auswählen

alias hxr="perl -ne'for(split){print chr hex}'"

for i in `seq 0 255`;do X=`printf "%x" $i`;echo $X|hxr|grep -Pq "\x$X"||echo censored: $i;done
censored: 10

... Entwarnung:

Code: Alles auswählen

for i in `seq 0 255`;do X=`printf "%x" $i`;echo $X|hxr|grep -Pqz "\x$X"||echo censored: $i;done
censored: 0

nur der Line Terminator:

-z, --null-data...........a data line ends in 0 byte, not newline
