Bash 如何用双引号将前10个逗号括起来？

这是我的input.csv文件

我需要用双引号将所有列括起来，这样我就可以得到这样一个文件：

"dealerid","address","city","state","zip","vin","stocknumber","type","color","year","make","model","trim","bodystyle","fueltype","mileage","transmission","interiorcolor","interiorfabric","price","titlestatus","warranty","options_text","cylinders","engine","engineaspiration","enginetext","drivetrain","transmissiontext","mpgcity","mpghighway","features_text","vdc_url","images"

该文件始终保持不变，某些列中缺少相同的数据

“图像”列和“功能”文本列已包装

看到同样的信息在整个过程中丢失，我决定在每行的开头加上双引号，并开始用双引号替换逗号，但开始遇到一些问题

这是我到目前为止所拥有的。我知道代码不是很有效，但这只是一个开始

#!/bin/bash

#- Temp Directories
tmp_dir="$(mktemp -d -t 'csv.XXXXX' || mktemp -d 2>/dev/null)"
tmp_input1="${tmp_dir}/temp_input1.csv"
tmp_input2="${tmp_dir}/temp_input2.csv"
tmp_input3="${tmp_dir}/temp_input3.csv"

#- Variables
client="00000"
wDir="$(pwd)"
ftpDir="${wDir}/.clientftp"
clientDir="${ftpDir}/${client}"
csvFile="${clientDir}/final.csv"
inputCsv="${wDir}/input.csv"

#  Lets Begin
cd "$wDir" || exit

      cp "$inputCsv" "$tmp_input1"
      dos2unix "$tmp_input1"

      #  place first line to a temp file , surrounding commas with double quotes , adding double quotes to the front and end of line
      head -1 "$tmp_input1" | sed -e 's/,/","/g;s/.*/"&"/' > "$tmp_input2"

      #  place remainding lines to a temp file
      sed 1,1d "$tmp_input1" | sed "s/^/\"/" > "$tmp_input3"
      sed -i 's/",,,,,,,,,,https/","","","","","","","","","","https/g' "$tmp_input3"
      sed -i 's/,Clear,Available,"/","Clear","Available","/g' "$tmp_input3"
      sed -i 's/,,,,/","","","","/g' "$tmp_input3"
      sed -i 's/,,,/","","","/g' "$tmp_input3"

      #  Create final file
      cat "$tmp_input2" > "$csvFile"
      cat "$tmp_input3" >> "$csvFile"

      rm -rf "$tmp_dir"

      { clear; echo ""; echo "";  echo "nano $csvFile"; echo ""; }

nano "$csvFile"

此脚本生成：

"dealerid","address","city","state","zip","vin","stocknumber","type","color","year","make","model","trim","bodystyle","fueltype","mileage","transmission","interiorcolor","interiorfabric","price","titlestatus","warranty","options_text","cylinders","engine","engineaspiration","enginetext","drivetrain","transmissiontext","mpgcity","mpghighway","features_text","vdc_url","images"

现在我有几个问题： 1-vdc_url列没有结束双引号 2-前10个逗号需要用双引号括起来

最后一列可以包含3个以上的图像

任何帮助都将不胜感激。

我喜欢ruby用于快速CVS转换：

ruby -rcsv -e '
    out = CSV.instance($stdout, {force_quotes: true})
    CSV.foreach(ARGV.shift) {|row| out << row}
' input.csv

确保在任何行上都没有任何尾随空格

这也是一个很好的解决方案。

对于FPAT的GNU awk：

$ awk -v FPAT='[^,]*|"[^"]*"' -v OFS=',' '
    { for (i=1;i<=NF;i++) {gsub(/^"|"$/,"",$i); $i="\"" $i "\""} }
1' file

您的预期输出为136000，第二行自动，但应该是136000，自动，对吗？@BenjaminW。是的，先生，所有栏目都应该用双引号括起来。抢手货还有，温莎999号公路应该是温莎999号公路。@BenjaminW。你说得对。看看格伦的答案。它似乎做到了这一点，而且非常有效。不管怎样，谢谢你的帮助，我很感激。现在这是关于最酷的4行代码或什么。。。没错，格伦！
