使用 bash 将多个 .csv 文件导入到 mysql
Import multiple .csv files to mysql using bash
我想使用 bash 脚本首先将文件从 google 驱动器复制到本地驱动器并重命名（删除空格并添加前缀），然后导入这些.csv 文件到 mysql 数据库中。这些 .csv 有不同的列，所以我需要从每个 .csv 中获取列名并使用这些列名创建一个 table，然后导入数据。
如有任何帮助，我将不胜感激。
我在此处 https://ericlondon.com/2011/04/10/a-bash-shell-script-to-import-a-large-number-of-csv-files-into-mysql.html 找到了一些代码，我已经对其进行了修改，但无法使其正常工作。我承认我不明白它的作用。
这是我目前的脚本：
#!/bin/bash
# show commands being executed, per debug
set -x
# define database connectivity
_db="dbname"
_db_user="user"
_db_password="password"
# delete existing files
rm -rf /path/to/*.csv
# copy files to local disk
cp /old/path/to/*.csv /path/to/
# define directory containing CSV files
_csv_directory="/path/to"
# go into directory
cd $_csv_directory || exit
# edit file name
rename "s/ //g" *.csv
rename "s/^/tp/g" *.csv
# get a list of CSV files in directory
_csv_files=`ls -1 *.csv`
# loop through csv files
for _csv_file in ${_csv_files[@]}
do
# remove file extension
_csv_file_extensionless=`echo "$_csv_file" | sed 's/\(.*\)\..*//'`
# define table name
_table_name="${_csv_file_extensionless}"
# get header columns from CSV file
_header_columns=`head -1 $_csv_directory/$_csv_file | tr ',' '\n' | sed 's/"//' | sed 's/ /_/g'`
_header_columns_string=`head -1 $_csv_directory/$_csv_file | sed 's/ /_/g' | sed 's/"//g' | sed 's/(//g' | sed 's/)//g'`
# ensure table exists
mysql -u $_db_user -p$_db_password $_db << eof
CREATE TABLE IF NOT EXISTS \`$_table_name\` ENGINE=MyISAM DEFAULT CHARSET=utf8
eof
# loop through header columns
for _header in "${_header_columns[@]}"
do
# add column
mysql -u $_db_user -p$_db_password $_db --execute="alter table \`$_table_name\` add column IF NOT EXISTS \`$_header\` text"
done
# import csv into mysql
mysqlimport --fields-enclosed-by='"' --fields-terminated-by=',' --lines-terminated-by="\r\n" --columns=$_header_columns_string -u $_db_user -p$_db_password $_db $_csv_directory/$_csv_file

exit

查看 CSV header 的 od 输出，似乎在 CSV 行的末尾有回车符 return 和换行符（\r\n 顺序）。 CSV 是否来自 Windows 下的处理？ \r\n 是 Windows 下常见的文本行终止符，而 Linux 仅使用 \n。 \r 作为字符串的一部分包含在内，不被视为行终止的一部分。它还会产生看起来很奇怪的输出，因为 \r 本身在输出时会将光标位置重置为第一列，并且后续字符显示在先前可能已显示在同一行上的任何内容的顶部。
我建议先 运行 dos2unix 在您的 CSV 文件上，然后再进行处理。我认为这将清除奇怪的错误并帮助文件的其余部分的处理也正常工作。
