awk变量给定错误

如何在awk中将输出作为变量

电流输出

cat ii

Iie:573T
Eed:448.0T
vail:74T

所需输出

Total Size : 573 TB
Total Used : 448.0 TB
Avilable   : 74 TB
Used (%)   : 86.10%   # Total Used(%) = Total Used/Total Size *100 = 86.1(%)

错误脚本不工作

cat ii | awk ' /Size:/ {total_size=$NF}
> /Used:/ { total_used=$NF }
> END{
TotalUsed= total_size=total_used
print "Total Used="TotalUsed}'

---

要获得

86.1%

您需要，Eed至少

493.353

见：

这里有一种打印修改的标题和百分比的方法

awk 'BEGIN{
           OFS=FS=":";
           h["Iie"]="Total Size";
           h["Eed"]="Total Used";
           h["vail"]="Avilable"
     }
     $1 in h{
           sub(/T/," TB",$2);
           print h[$1], $2; 
           h[$1]=$2 
     }
     END{
           print "Used (%)",h["Eed"]/h["Iie"]*100
     }
    ' infile

输入：

$ cat infile
Iie:573T
Eed:448.0T
vail:74T

输出：

$ awk 'BEGIN{OFS=FS=":";h["Iie"]="Total Size";h["Eed"]="Total Used";h["vail"]="Avilable"}$1 in h{sub(/T/," TB",$2);print h[$1],$2; h[$1]=$2 }END{print "Used (%)",h["Eed"]/h["Iie"]*100}' infile
Total Size:573 TB
Total Used:448.0 TB
Avilable:74 TB
Used (%):78.185

解释

awk 'BEGIN{
           OFS=FS=":";                           # i/p and o/p field sep
           h["Iie"]="Total Size";                # array of key and values
           h["Eed"]="Total Used";
           h["vail"]="Avilable"
     }
     $1 in h{                                    # if its of our interest and in array h

                                                 # in current context
                                                 # skips saving any unwanted column in array h

           sub(/T/," TB",$2);                    # substiute T with space and TB
                                                 # can also be " &B"
           print h[$1], $2;                      # print corresponding header and 2nd field
           h[$1]=$2                              # we are done save value
     }
     END{
