在管道中排序不起作用

我有很多這些文件，我想知道什麼是最高的記憶體消耗（Mem）

我用過grep "Mem" *-racon-2.fasta.o* | cut -d':' -f3 | sed 's|kb||'| sed 's|b||' |awk '{print $1}' | sort，但它沒有對輸出進行排序

我錯過了什麼？

先感謝您

cut -d':' -f3將從一行中提取 3rd :-delimited 欄位，但您應用它的行看起來像

Mem usage : 4960216kb

即，它只有兩個欄位：

1. Mem usage， 和
2. 4960216kb.

為了避免冗長的管道，您可以改用

sed -n '/^Mem/s/[^[:digit:]]*//gp' *-racon-2.fasta.o* | sort -n

這使用單個sed呼叫來提取以字元串開頭的行，Mem並通過刪除這些行上不是數字的所有內容來刪除數字。然後它將提取的數字傳遞sort -n給數字排序。

這相當於

grep '^Mem' *-racon-2.fasta.o* | tr -d -c '[:digit:]\n' | sort -n
