Linux使用备忘

使用echo命令写入文件

在容器化部署的条件下，为了减小容器体积，经常会使用非常精简的操作系统，不含有Vim编辑器，此时可以借助echo命令将文本内容直接输出到文件，例如：使用echo命令创建一个cert.csr文件并填充其内容（其中>用于覆盖原有文件，>>能够追加文件内容）：

echo "-----BEGIN CERTIFICATE REQUEST-----" > cert.csr
echo "MIIC0jCCAboCAQAwWzELMAkGA1UEBhMCQ04xEjAQBgNVBAgMCUd1YW5nZG9uZzER" >> cert.csr
echo "MA8GA1UEBwwIU2hlbnpoZW4xDDAKBgNVBAoMA0RBUzEXMBUGA1UEAwwOMTIwLjc4" >> cert.csr

查找满足要求的文件并进行批量移动

其中\; 表示 -exec 选项的结束符。它告诉 find 命令在执行完命令（如 mv）后结束当前的执行。\ 是转义字符，用来确保 ; 被解释为命令的一部分，而不是终止命令行的分号。

find . -name "*example*" -exec mv {} /path/to/destination \;
