我有一个 .CSV 文件 (file.csv),其数据全部用双引号引起来。文件的示例格式如下:
column1,column2,column3,column4,column5,column6, column7, Column8, Column9, Column10
"12","B000QRIGJ4","4432","string with quotes, and with a comma, and colon: in between","4432","author1, name","890","88","11-OCT-11","12"
"4432","B000QRIGJ4","890","another, string with quotes, and with more than, two commas: in between","455","author2, name","12","455","12-OCT-11","55"
"11","B000QRIGJ4","77","string with, commas and (paranthesis) and : colans, in between","12","author3, name","333","22","13-OCT-11","232"
第9个字段是格式中的日期字段“DD-MMM-YY”。我必须将其转换为格式年/月/日。我试图使用下面的代码,但没有用。
awk -F, '
BEGIN {
split("JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC", month, " ")
for (i=1; i<=12; i++) mdigit[month[i]]=i
}
{ m=substr($9,4,3)
$9 = sprintf("%02d/%02d/"20"%02d",mdigit[m],substr($9,1,2),substr($9,8,20))
print
}' OFS="," file.csv > temp_file.csv
执行上述代码后,文件 temp_file.csv 的输出如下所示。
column1,column2,column3,column4,column5,column6,column7,Column8,00/00/2000,Column10
"12","B000QRIGJ4","4432","string with quotes, and with a comma, and colon: in between","4432","author1,00/00/2000,"890","88","11-OCT-11","12"
"4432","B000QRIGJ4","890","another, string with quotes, and with more than, two commas: in between","455",00/00/2002, name","12","455","12-OCT-11","55"
"11","B000QRIGJ4","77","string with, commas and (paranthesis) and : colans, in between","12","author3,00/00/2000,"333","22","13-OCT-11","232"
据我了解,问题在于双引号中的逗号,因为我的代码也考虑了它们......请就以下问题提出建议:
1)双引号所有字段中的所有值有什么区别吗?如果它们有任何区别,我如何从除带逗号的字符串之外的所有值中删除它们?
2)对我的代码进行任何修改,以便我可以格式化第9个字段,其格式为“日-月-年” to 年/月/日
