/bin/bash # 指定要遍历的目录 directory="/path/to/directory" # 遍历目录下的所有文件和子目录 for file in "$directory"/* do if [ -d "$file" ]; then # 处理子目录 echo "子目录: $file" # 在这里可以进行其他操作,如进入子目录继续遍历等 elif [ -f "$file" ]; then # 处理文件 echo ...
Bash是一种Unix Shell和命令语言,它是一种脚本语言,用于在Unix和Linux系统中执行命令和自动化任务。通过for-in-loop执行文件是指使用Bash中的循环结构来遍历文件列表并执行相应的操作。 在Bash中,可以使用for-in-loop来遍历文件列表。具体的语法如下: 代码语言:txt 复制 for file in <文件列表> do # 执行操作,...

for-loop基本上是健全的。但是,如果目录为空,循环将执行一次,变量file包含文本/var/spool/bandit24/*。 stat消息不是来自for-loop,而是来自循环中的一个命令。 正确的方法是在继续之前测试目录是否为空。你可以把 if [ $(find . -type f | wc -l) -eq 0 ] ; then ...
