Question

我正在写一个脚本来修改csv文件。这是我的格式文件：

＆＃34; ID＆＃34;＆＃34;类型＆＃34;＆＃34;日期＆＃34;＆＃34;松开＆＃34;＆＃34;版本＆＃34;
  ＆＃34; 1＆＃34;，＆＃34;安全更新＆＃34;，＆＃34; 2014-09-23＆＃34;，＆＃34; 1.3-0.1＆＃34;，＆＃34; 2＆＃ 34;
  ＆＃34; 2＆＃34;，＆＃34; Bug修复＆＃34;，＆＃34; 2014-09-23＆＃34;，＆＃34; 1.3-0.1＆＃34;，＆＃34; 2＆＃ 34;
  ＃＆34; 3＆＃34;＆＃34;增强＆＃34;＆＃34; 2014年9月23日＆＃34;＆＃34; 1.3-0.1＆＃34;＆＃34; 2＆＃34 ;

我想更改＆＃34;安全更新＆＃34;到＆＃34;高＆＃34; ，＆＃34; Bug Fix＆＃34; to＆＃34; Medium＆＃34;和＃34;增强＆＃34;到＆＃34;正常＆＃34;

有没有人给我一个想法？
感谢

Answer 1

这将在整个文件中用所需的替换替换关键字的每个实例。

awk '{gsub(/Security Update/,"High")}; 1'
awk '{gsub(/Bug Fix/,"Medium")}; 1'
awk '{gsub(/Enhancement/,"Normal")}; 1'

但请注意，即使关键字不在第二列中，也会匹配关键字。

Answer 2

鉴于此示例文件：

"id","type","date","release","version"
"1","Security Update","2014-09-23","1.3-0.1","2"
"2","Bug Fix","2014-09-23","1.3-0.1","2"
"3","Enhancement","2014-09-23","1.3-0.1","2"

使用Python进行更改非常容易：

$ python -c '
import csv, fileinput
update={"Security Update": "High", "Bug Fix": "Medium", "Enhancement":"Normal"}
for line in csv.reader(fileinput.input()):
    if line[1] in update: line[1]=update[line[1]]
    print ",".join(repr(e) for e in line)' file.csv 
'id','type','date','release','version'
'1','High','2014-09-23','1.3-0.1','2'
'2','Medium','2014-09-23','1.3-0.1','2'
'3','Normal','2014-09-23','1.3-0.1','2'

Answer 3

你可以用sed做到这一点。

sed 's/Security Update/High/g;s/Bug Fix/Medium/g;s/Enhancement/Normal/g'

用awk替换字符串特定列
