在 Ubuntu 上删除换行符 \n 但不返回 \r答案

【问题标题】：On Ubuntu remove linefeed \n but NOT return \r在 Ubuntu 上删除换行符 \n 但不返回 \r

【问题描述】：

在 Ubuntu 上，我有以下输入 csv 数据，其中有需要删除的换行符，但保留回车符，以便记录保留在单独的行中。在记事本++中，LF和CRLF实际显示：

"data","","AO1","AO1","9/30/2019 5:58:07 AM","data data","AO1","AO1","","","data","","","data","fndata","lndata","","datedata","data","653","datedata","","","data%","","","English","Expressive","","","","","","","9/30/2019","","","","","emdata","data","","","","","","","St.data","","citydata","data","zipdata","","0","","","","","","","","","","","","","","","","","","","","","","","","","0","","data","Lorem Ipsum data data  data

data data","","","","","","","9/30/2019 5:58:07 AM"

我试过 tr '\n' ' '

我也在 python 中尝试了下面的代码，它在 windows 中有效，但在 ubuntu 上无效

def replaceall(file, searchexp, replaceexp):
    backup = file + '.bak'
    os.rename(file,  backup)
    with open(backup, 'r', newline='') as source, open(file, 'w', newline='') as dest:
        for line in source:
            if searchexp in line:
                line = line.replace(searchexp, replaceexp)
            dest.write(line)

我希望这一行会出现在一个赞上并保持回车不变。

意识到我可以在 Ubuntu 上使用上面的 python 代码将 \n 替换为空格，然后重新运行并将 \r 替换为 \r\n 并清理文件。

对噪音感到抱歉，但希望它可以帮助其他人。
