我尝试在 bash 中向 mysql 插入字符串，所以我执行以下操作：

message="<a href = http://www."
message="$message ${d}"
message="$message .com"
mysql -u root -pmypass -Bse 'INSERT INTO atTable VALUES (null, "'$message'")'

当我这样做时，我会得到下一个按摩：

mysql  Ver 14.14 Distrib 5.1.69, for debian-linux-gnu (i486) using readline 6.1

Usage: mysql [OPTIONS] [database]
  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time. Disable with
                      --disable-auto-rehash.
  -A, --no-auto-rehash
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect.
  -B, --batch         Don't use history file. Disable interactive behavior.
                      (Enables --silent.)
  --character-sets-dir=name
                      Directory for character set files.

和其他命令。我做错了什么？

请试试这个：

message="<a href = http://www."
message="$message ${d}"
message="$message .com"
mysql -u root -pmypass -Bse "INSERT INTO atTable VALUES (null, '$message')";

至少它对我有用，当我用这个测试它时：

message="<a href = http://www."
message="$message hello"
message="$message .com"
mysql -u root -pwhatever -Bse "SELECT '$message'";

尝试这个：

mysql -u root -pmypass -Bse "INSERT INTO atTable VALUES (null, '$message')"

问题是空格$message结束了这个-e选项。

  1. 而不是像你一样拼凑message变量，这更容易阅读：

    message="<a href = http://www. $d .com"

    这相当于原始帖子中的示例，尽管文本本身看起来没有意义。

  2. 您可以将查询传递给mysql这样的：

    mysql -u root -pmypass -Bse  "INSERT INTO atTable VALUES (null, '$message')"

  3. 如果message包含单引号，你需要转义它们，你可以这样做：

    message=$(echo "$message" | sed -e "s/'/\\\\'/")

  4. 我建议不要将您的 root 密码放在命令行上，而是将该信息放在.my.cnf您的主目录的文件中，例如：

    [client]
database=yourdbname
user=root
password=yourpass

    但是， 在输入真实密码之前，请先保护文件，如下所示：

    touch .my.cnf
chmod 600 .my.cnf
