gerrit_url=http://a/1234/11/+/1666,我想用linux筛选出+/后面的数字该怎么办

要从 `gerrit_url` 中提取出 `+/` 后面的数字，可以使用 Linux 命令行工具中的字符串操作和正则表达式。

下面是一个使用 `grep` 命令和正则表达式的示例：

echo "gerrit_url=http://a/1234/11/+/1666" | grep -oP '(?<=\+/)\d+'

解释：
- `echo "gerrit_url=http://a/1234/11/+/1666"` 用于将字符串输出到标准输出。
- `grep -oP '(?<=\+/)\d+'` 是使用 `grep` 命令，其中 `-o` 选项表示只输出匹配的部分，`-P` 选项表示使用 Perl 正则表达式。
- `(?<=\+/)` 是一个正向查找，表示匹配 `+/`，但不包括在结果中。
- `\d+` 表示匹配一个或多个数字。

运行上述命令后，将输出 `1666`，即 `+/` 后面的数字。

请注意，上述命令仅适用于在 Linux 命令行环境下执行。如果你将其放入脚本中，请确保适当地将变量 `gerrit_url` 替换为实际的变量名。
