Question

我的文件包含以下内容。例如2张图片尺寸为FRAGMENT。我想用bash脚本计算片段总大小。

ForEach ($emailAddress in $list) { 
    if (IsValidEmail($emailAddress)) { 
        "Valid: {0}" -f $emailAddress
        Out-File -Append C:\Emails\ValidEmails\ValidEmails.csv -Encoding UTF8
        $EmailAddressImp | Export-Csv "C:\Emails\ValidEmails\ValidEmails.csv" 
        -NoTypeInformation
    } 
    else { 
        "Invalid: {0}" -f $emailAddress 
        Out-File -Append C:\Emails\InValidEmails\InValidEmails.csv -
        Encoding UTF8
        $EmailAddressImp | Export-Csv 
        "C:\Emails\InValidEmails\InValidEmails.csv" -NoTypeInformation
    }     
}

输出应该是这样的：

IMAGE admindb1 8 admindb1_1514997916 bus 4 Default-Application-Backup 2 3 1 1517676316 0 0
FRAG 1 1 10784 0 2 6 2 HSBRQ2 fuj 65536 329579 1514995208 60 0 *NULL* 1517676316 0 3 1 *NULL*

IMAGE admindb1 8 admindb1_1514995211 bus 4 Default-Application-Backup 2 3 1 1517673611 0 0
FRAG 1 1 13168256 0 2 6 12 HSBQ8I fuj 65536 173783 1514316708 52 0 *NULL* 1517673611 0 3 1 *NULL*

应该计算以FRAG开头的第4列。

我的脚本无效：

For Image admindb1_1514997916  total size is 10784
For Image  admindb1_1514995211  total size is 75551776

Answer 1

awk 'function summary() {print "For Image",image,"total size is",sum} 
     $1=="IMAGE" {image=$4}                         
     $1=="FRAG" {sum+=$4} 
     $1=="" {summary(); sum=0}
     END{summary()}' file

输出：

For Image admindb1_1514997916 total size is 10784
For Image admindb1_1514995211 total size is 75551776

我假设最后一行不是空的。

Answer 2

cat -s file.txt | sed -n '/^IMAGE /{s:^[^ ]*  *[^ ]*  *[^ ]*  *\([^ ]*\).*$:echo -n "For image \1 total size is "; echo `echo ":;s:\*::g;p};/^$/{s:^:0"`|bc:;p};/^FRAG /{s:^[^ ]*  *[^ ]*  *[^ ]*  *\([^ ]*\).*$:\1\+:;s:\*::g;p};' | bash

输出：

For image admindb1_1514997916 total size is 10784
For image admindb1_1514995211 total size is 75551776

Answer 3

Awk 解决方案：

awk '/^IMAGE/{ 
         if (t) { printf "For image %s total size is %d\n",img,t; t=0 } img=$4 
     }
     /^FRAG/{ t+=$4 }
     END{ if (t) printf "For image %s total size is %d\n",img,t }' file

输出：

For image admindb1_1514997916 total size is 10784
For image admindb1_1514995211 total size is 75551776

Answer 4

cut， GNU sed的粗略组合，（不小心使用e 评估）和{{ 3}}：

cut -d' ' -f4 file | datamash --no-strict transpose | 
sed 's#\tN/A\t#\n#g;y#\t# #' | 
sed 's/ \(.*\)/ $((\1))/;y/ /+/;s/+/ /;
     s/\(.*\) \(.*\)/echo For image \1  total size is \2/e'

输出：

For image admindb1_1514997916 total size is 10784
For image admindb1_1514995211 total size is 75551776

datamash更好。这个答案显示了sed的一些限制。此外，如果数据文件很大（比如数百万个数字总和），那么用于对shell添加的e 评估可能会超出其命令行长度限制。< / p>

通过bash脚本计算文件中的数字
