du with colored bar graph

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.


There are 4 alternatives - vote for the best!

Terminal - Alternatives
du -x --max-depth=1|sort -rn|awk -F / -v c=$COLUMNS 'NR==1{t=$1} NR>1{r=int($1/t*c+.5); b="\033[1;31m"; for (i=0; i<r; i++) b=b"#"; printf " %5.2f%% %s\033[0m %s\n", $1/t*100, b, $2}'|tac

Functions: awk du printf sort

A more efficient way, with reversed order to put the focus in the big ones.

Know a better way?

Getting this error.

du: warning: summarising conflicts with --max-depth=1

Comment by MrMuddle 230 weeks and 3 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 ?

Comment by kevinquinnyo 230 weeks and 3 days ago

Ubuntu 10.10 x64

du (GNU coreutils) 8.5


Comment by MrMuddle 230 weeks and 3 days ago

what happens when you run:

sudo du / --max-depth=1|sort -rn -k1

Comment by kevinquinnyo 230 weeks and 3 days ago

Same thing bud :|

Comment by MrMuddle 230 weeks and 3 days ago

Got it right!


Comment by unixmonkey14651 230 weeks and 3 days ago

"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}

Comment by BrokenDroid 229 weeks and 2 days ago

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?

Comment by point_to_null 33 weeks ago

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.
