我有以下命令，它为我提供了我的 hadoop 集群中一堆文件夹的大小(以字节为单位):

$ hdfs dfs -du -s /foo/bar/*tobedeleted | sort -r -k 1 -g | awk '{print $1, $3}'
31641789771845 /foo/bar/card_dim_h_tobedeleted
22541622495592 /foo/bar/transaction_item_fct_tobedeleted
3174354180367 /foo/bar/card_dim_h_new_tobedeleted
2336463389768 /foo/bar/hshd_loyalty_seg_tobedeleted
1238268384713 /foo/bar/prod_dim_h_tobedeleted
652639933614 /foo/bar/promo_item_fct_tobedeleted
490394392674 /foo/bar/card_dim_c_tobedeleted
365312782231 /foo/bar/ch_contact_offer_alc_fct_tobedeleted
218694228546 /foo/bar/prod_dim_h_new_tobedeleted
197884747070 /foo/bar/card_dim_h_test_tobedeleted
178553987067 /foo/bar/offer_dim_h_tobedeleted
124005189706 /foo/bar/promo_dim_h_tobedeleted
94380212623 /foo/bar/offer_tier_dtl_h_tobedeleted
91109144322 /foo/bar/ch_contact_offer_dlv_fct_tobedeleted
54487330914 /foo/bar/ch_contact_event_dlv_fct_tobedeleted

我想要的是用 GB/TB 后缀格式化这些数字。我知道我可以使用 du -h 来格式化它们，但是一旦我这样做了 sort 命令就不起作用了。

我知道我可以做这样的事情:

$ hdfs dfs -du -s /foo/bar/*tobedeleted | sort -r -k 1 -g | awk '{print $1, $3}' | awk '{total = $1 / 1024 /1024 / 1024 / 1024; print total "TB", $2}'
28.778TB /foo/bar/card_dim_h_tobedeleted
20.5015TB /foo/bar/transaction_item_fct_tobedeleted
2.88706TB /foo/bar/card_dim_h_new_tobedeleted
2.125TB /foo/bar/hshd_loyalty_seg_tobedeleted
1.1262TB /foo/bar/prod_dim_h_tobedeleted
0.593573TB /foo/bar/promo_item_fct_tobedeleted
0.446011TB /foo/bar/card_dim_c_tobedeleted
0.33225TB /foo/bar/ch_contact_offer_alc_fct_tobedeleted
0.198901TB /foo/bar/prod_dim_h_new_tobedeleted
0.179975TB /foo/bar/card_dim_h_test_tobedeleted
0.162394TB /foo/bar/offer_dim_h_tobedeleted
0.112782TB /foo/bar/promo_dim_h_tobedeleted
0.0858383TB /foo/bar/offer_tier_dtl_h_tobedeleted
0.0828633TB /foo/bar/ch_contact_offer_dlv_fct_tobedeleted
0.0495559TB /foo/bar/ch_contact_event_dlv_fct_tobedeleted

但这将所有内容都打印为 TB，这不是我想要的。可能我可以在最后一个 awk 命令中加入一些聪明的 if...then...else 逻辑来做我想做的事，但我希望有一个我不知道的简单格式化选项可以做我想做的事。

最佳答案

也许这就是您正在寻找的:

hdfs dfs -du -s /foo/bar/*tobedeleted | \
    sort -r -k 1 -g | \
    awk '{ suffix=" KMGT"; for(i=1; $1>1024 && i < length(suffix); i++) $1/=1024; print int($1) substr(suffix, i, 1), $3; }'
