Question

我有一个工作脚本，该脚本分析文本文件并从输出中创建一个新文件。如何针对单个文件或文件目录运行此脚本？以下是工作脚本的一般概述。谢谢您的帮助。

#!/usr/bin/env bash

if [ -f "$1" ]; then
    *Run Some Commands against file* "$1" >> NewFile.txt
    echo "Complete. Check NewFile.txt"
else
    echo "Expected a file at $1, but it doesn't exist." >&2
fi

Answer 1

您可以检查传递的参数是否为目录，如果是，则编写循环以处理该目录中的文件：

#!/usr/bin/env bash

if (($# = 0)); then
    echo "No arguments given" >&2
    exit 2
fi

arg=$1
if [ -f "$arg" ]; then
    *Run Some Commands against file* "$1" >> NewFile.txt
    echo "Complete. Check NewFile.txt"
elif [ -d "$arg" ]; then
    shopt -s nullglob
    for file in "$arg"/*; do
        # run command against "$file"
    done
else
    echo "Expected a file or directory as $1, but it doesn't exist." >&2
fi

Answer 2

一个更简单的解决方案（也可以递归）是使其具有X维度：

#!/usr/bin/env bash

if [ -d $1 ]; then
  for i in $1/*; do
    # start another instance of this script
    $0 $1/$i
  done
fi

if [ -f "$1" ]; then
    *Run Some Commands against file* "$1" >> NewFile.txt
    echo "Complete. Check NewFile.txt"
else
    echo "Expected a file at $1, but it doesn't exist." >&2
fi

针对目录或文件运行脚本
