Question

我正在尝试将特定目录上的内容rsync到另一台服务器并创建脚本以使其自动化。我的脚本将检查该目录的内容是否包含文件或文件夹，然后使用rsync移动它们。下面，

#!/bin/bash

for i in `ls /root/tags/` ; do
if [ -f "$i" ]
then
  echo "this is a file and I'll run a script if it is a file"
else
if [ -d "$i" ]
then
  echo "this is a dir and I'll run a script if it is a directory"
fi
fi
done

正如你所看到的，我对shell脚本的了解不是什么值得大喊大叫的，但我正试图让它工作。

另一种选择是

cd /root/tags
for i in * ; do
  if [ -f "$i" ]; then
    echo "this is a file and I'll run a script if it is a file"
  elif [ -d "$i" ]; then
    echo "this is a dir and I'll run a script if it is a directory"
  fi
done

这与

相同

path="/root/tags"
for i in "${path%/}"/* ; do
  if [ -f "$i" ]; then
    echo "this is a file and I'll run a script if it is a file"
  elif [ -d "$i" ]; then
    echo "this is a dir and I'll run a script if it is a directory"
  fi
done

我发现这是一个很好的可重用代码。

Answer 2

您对else if的使用不正确，应为elif

if [ -f "$i" ]; then
  echo "this is a file and I'll run a script if it is a file"
elif [ -d "$i" ]; then
  echo "this is a dir and I'll run a script if it is a directory"
fi

Answer 3

要确保名称中包含空格的文件不会导致问题，请使用以下内容：

find . -maxdepth 1 -print0 | while read -d "" file ; do
    if [ -f "$file" ] ; then
        echo "$file is a file and I'll run a script if it is a file"
    elif [ -d "$file" ] ; then
        echo "$file is a dir and I'll run a script if it is a directory"
    fi
done

用于检查它是目录还是文件的脚本，然后处理脚本的其余部分
