我有类似以下CSV的内容:
"blah blah, foo bar", 1, 454, ok, eng
blah blah foo bar, 2, 21, ko, esp
...
我需要将字段之间的逗号替换为分号,以便我可以正确拆分CSV。但不要在quoutes里面。
我需要或正则表达一个小脚本(python,groovy,bash ......)来解决这个问题。

考虑使用Python的csv
模块。演示:
from csv import reader, writer
with open('input.csv') as inp, open('output.csv', 'w') as out:
writer(out, delimiter=';').writerows(reader(inp))
文件内容:
$ cat input.csv
"blah blah, foo bar", 1, 454, ok, eng
blah blah foo bar, 2, 21, ko, esp
$ cat output.csv
blah blah, foo bar; 1; 454; ok; eng
blah blah foo bar; 2; 21; ko; esp

import csv
infile = open("inputfile.csv", "r")
outfile = open("outputfile.csv", "w")
csvReader = csv.reader(infile)
for line in csvReader:
outfile.write(";".join(line) + "\n")
infile.close()
outfile.close()
在Python 2.7和3.5上测试
示例输出:
blah blah, foo bar; 1; 454; ok; eng
blah blah foo bar; 2; 21; ko; esp
