linux - BASH : Sum size of same name directories -

-

first of all, bash noob, please gentle :)

i trying sum size of folders in different places have same name. looks :

root --- directory 1  ------ folder 1 --------subfolder 1 --------subfolder 2 ------ folder 2 --------subfolder 3 --------subfolder 4 ------ folder 3 --------subfolder 5 --------subfolder 6  --- directory 2  ------ folder 1 --------subfolder 1 --------subfolder 2 ------ folder 2 --------subfolder 3 --------subfolder 4 ------ folder 3 --------subfolder 5 --------subfolder 6

i trying sum size of subdirectories 1 6 , output .csv

at moment outputting sizes of subdirectories in 2 seperate csv files. 1 directory 1 , 1 directory 2

at moment have output sizes of subfodlers run need them :

du -h --max-depth=1 --block-size=gb * | grep "[\/]" | sort -n -r > ~/lists/disks/rc_job.csv

the output :

40gb folder1/subfolder1  15gb folder1/subfolder2  10gb folder2/subfolder 3 ...

i have 1 output directory 1 , 1 directory 2. sum size of subfolders directory 1 , 2 , have output looks 

60gb subfolder1  25gb subfolder2  10gb subfolder3

where subfolder1 directory1/folder1/subfolder1 + directory2/folder1/subfolder1

this first post here not know if enough info. pleased provide more if necessary. pretty sure can done awl, haven't used yet.

cheers !

edit answer question in comments :

(part of the) output of du -h /net/rcq-rp/job/rcq/vault/image/film /net/rcq-rp/job/rcq/film --max-depth=1 --block-size=gb * :

1gb /net/rcq-rp/job/rcq/vault/image/film/nr106/nr106_0010 1gb /net/rcq-rp/job/rcq/vault/image/film/nr106/nr106_0020 1gb /net/rcq-rp/job/rcq/vault/image/film/nr106/nr106_0030 1gb /net/rcq-rp/job/rcq/vault/image/film/nr106/nr106_0035 1gb /net/rcq-rp/job/rcq/vault/image/film/nr106/nr106_0040 1gb /net/rcq-rp/job/rcq/vault/image/film/nr106/nr106_0045 2gb /net/rcq-rp/job/rcq/vault/image/film/nr106/nr106_0050 1gb /net/rcq-rp/job/rcq/vault/image/film/nr106/nr106_0060 1gb /net/rcq-rp/job/rcq/film/nr106/nr106_0010 1gb /net/rcq-rp/job/rcq/film/nr106/nr106_0020 1gb /net/rcq-rp/job/rcq/film/nr106/nr106_0030 1gb /net/rcq-rp/job/rcq/film/nr106/nr106_0035 1gb /net/rcq-rp/job/rcq/film/nr106/nr106_0040 1gb /net/rcq-rp/job/rcq/film/nr106/nr106_0045 1gb /net/rcq-rp/job/rcq/film/nr106/nr106_0050 1gb /net/rcq-rp/job/rcq/film/nr106/nr106_0060

ideally final output :

2gb nr106_0010  etc...

one way associative array. associative array maps series of keys values, example:

directory1 -> 10 gb directory2 -> 12 mb directory3 -> 40 kb

the keys in associative array must unique. that's great! paths our directories unique. let's put them in associative array. show how in awk plenty of other languages have associative arrays (like perl, calls them hashes).

du | awk '{ val = $1; dir = $2; sizes[dir] = val }'

(i took out arguments pass du simplicity)

what do? awk reads output of du line line; each line, adds element associative array sizes directory name index , size value. if our original input looked this

40gb folder1/subfolder1 15gb folder1/subfolder2 10gb folder2/subfolder1

our array this:

sizes[folder1/subfolder1] -> 40gb sizes[folder1/subfolder2] -> 15gb sizes[folder2/subfolder1] -> 10gb

but in our final output want see values subdirectories. awk has functions string manipulation, let's tweak our code strip off leading directories:

du | awk '{ val = $1; dir = $2; sub(/^.*\//, "", dir); sizes[dir] = val }'

the sub function strips off last / beginning of path. our array looks this:

sizes[subfolder2] -> 15gb sizes[subfolder1] -> 10gb

great! have values subdirectories. there's 1 little problem. values aren't totals. since had more 1 subdirectory named subfolder1, overwrote first value (40gb) second 1 (10gb). when run index exists in our array, want add value existing value:

du | awk '{ val = $1; dir = $2; sub(/^.*\//, "", dir); sizes[dir] += val }'

(i changed sizes[dir] = val, uses assignment, sizes[dir] += val, adds val whatever in sizes[dir])

awk magically takes care of things us, converting 15gb number 15. our array looks this:

sizes[subfolder2] -> 15 sizes[subfolder1] -> 50

which shows totals we're looking for. now, how display this? can loop through array , print out keys , values this:

du | awk '{ val = $1; dir = $2; sub(/^.*\//, "", dir); sizes[dir] += val } \           end { (dir in sizes) print dir, sizes[dir], "gb" }'

and our results are

subfolder1 50 gb subfolder2 15 gb

edit: here results using du output in updated question.

nr106_0060 2 gb nr106_0050 3 gb nr106_0045 2 gb nr106_0040 2 gb nr106_0035 2 gb nr106_0030 2 gb nr106_0020 2 gb nr106_0010 2 gb

erlang - Saving a digraph to mnesia is hindered because of its side-effects -

-
updated the digraph library in erlang implements data type side-effectful. each operation on data type saves new state in ets table -- instead of returning altered version of itself, more common in functional languages. the problem usage perspective, impedes effort store or pass around state in convenient way requiring me first "collect" state before can start juggle around. the closest solution have seen far serializer/deserializer , these have drawback tied current structure of digraphs instead of operating on abstract type -- prevents future proof solution. update pascal pointed out serializer utilizes interface of digraph, , hence eliminates drawback mentioned above. better, albeit still inconvenient, see no better alternative. what recommendation on how store digraphs? should go different data type altogether? thanks. i not sure understand concern. fact digraph stored in ets transparent in user interface, might want chnge either exchange digr...

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...
