du with colored bar graph

t=$(df|awk 'NR!=1{sum+=$2}END{print sum}');sudo du / --max-depth=1|sed '$d'|sort -rn -k1 | awk -v t=$t 'OFMT="%d" {M=64; for (a=0;a<$1;a++){if (a>c){c=a}}br=a/c;b=M*br;for(x=0;x<b;x++){printf "\033[1;31m" "|" "\033[0m"}print " "$2" "(a/t*100)"% total"}'
i'm using gawk, you may get varying mileage with other varieties. You might want to change the / after du to say, /home/ or /var or something, otherwise this command might take quite some time to complete. Sorry it's so obsfucated, I had to turn a script into a one-liner under 255 characters for commandlinefu. Note: the bar ratio is relative, so the highest ratio of the total disk, "anchors" the rest of the graph. EDIT: the math was slightly wrong, fixed it. Also, made it compliant with older versions of df.

What Others Think

Getting this error. du: warning: summarising conflicts with --max-depth=1
MrMuddle · 511 weeks and 6 days ago
Not sure why that would happen. According to the du source code, that should only happen: if (opt_summarize_only && max_depth_specified && max_depth != 0) and unless you added a max-depth=0, or -s, i'm not sure why it would give you that error. I'm curios, what version of du are you running, and what OS ?

Ubuntu 10.10 x64 du (GNU coreutils) 8.5 Cheers

what happens when you run: sudo du / --max-depth=1|sort -rn -k1

Same thing bud :|
MrMuddle · 511 weeks and 6 days ago
Got it right! Thanks

"for (a=0;ac){c=a}}" this loop is completely useless (and also responsable of the slowness of your command since a can be very large) substitute it with a=$1; if (a>c){c=a}

Yeah; that loop (and the rest of the structure) is kinda you dont know about awk. Why are you even using du, a second instance of awk and not using $COLUMNS value?

Sorry. I mean to say "why are you even using sed". And also; thanks by sharing. When using AWK try to put all the logic inside. It's a very powerful language.
