Question

对 .sh 是全新的，我正在尝试从旧的 iPhone 备份图像，其中图像被放置到新目录中以供日期使用。有数百个目录，我需要从每个目录中获取图片并将它们全部转储到一个目录中。

我最好的尝试：

#!/bin/bash
function process () {

a=1
for i in *
do
  cp -r i ${dir}
  let a=a+1
done

}

#Interview
echo "This script will take the contents of each directory in the current directory and move it's contents into a new directory that you will specify"
echo "Name your new directory"
read dir

#Confirm
read -p "Your new directory will be ${dir}. Continue?" -n 1 -r
echo
if [[ $REPLY =~ ^[Yy]$ ]]
  then
  process
fi

收到错误：

massmove.sh: line 1: $'\r': command not found
massmove.sh: line 2: $'\r': command not found
massmove.sh: line 3: $'\r': command not found
massmove.sh: line 4: syntax error near unexpected token `$'{\r''
'assmove.sh: line 4: `function process () {

更新：通过 deefff 的回答改进：

function process () {

for i in */*.*
do
  cp -r $i ${dir}

done

}

echo "This script will take the contents of each directory in the current directory and mv it's contents into a new directory that you will specify"
echo "Name your new directory"
read dir
mkdir ${dir}

echo process

仍然抛出这些错误：

massmove.sh: line 2: syntax error near unexpected token `$'{\r''
'assmove.sh: line 2: `function process () {

这可能是 WSL 错误吗？

我明白

 cp */*.* ${dir}

是完成我的任务的一种快速而强大的方法，但我也对导致错误的原因非常感兴趣。

Answer 1

* 将匹配每个条目，包括目录，因此在当前形式下，它将复制整个目录结构，我想这不是您想要的。此外，您应该在 cp 命令中将变量 i 称为 $i。此外， a 变量似乎毫无意义。像这样尝试：

function process () {

for i in */*.*
do
  cp $i ${dir}
done

}

事实上，我刚刚意识到这也能解决问题：

cp */*.* ${dir}

Answer 2

尝试这样的事情：

function process () {
    for file in *; do
        if [[ ${file} != ${dir} ]]; then
            cp -r ${file} ${dir}
        fi
    done
}

此外，记得在调用 'process' 函数之前创建目录：

echo "Name your new directory: "
read dir
mkdir ${dir}

请看下面我的脚本。

它基本上有3个功能：菜单、prnt（用于打印带日期的行）和process（处理文件）。它有一个菜单，可以与选项一起使用。希望大家喜欢

#!/bin/bash

        echo "$d|"      # Whenever prnt is called, it will echo back, date plus the line passed to it, in nice date|line format.
}

# Menu for the whole operation. This is just the definition. Its being called from the bottom of the script.

                echo ; prnt "Invalid input. Please enter y or n or 0 !!" ; echo
                ;;

        esac    # Menu using case function ends with esac here.

}

# Function to process and move the files to the desired location.
process()
{
        # Took the argument passed to this function into variable "td" [target dirctory].

        td=""

        # Using find command here to find all files. You an replace '-type f' with '-name "*.pic"' or '-name "*.jpg"' -- you get the picture - right?

        find $curdir -type f | while read file  # Feeding output of find to a while loop.
        do
                cp $file $td/
        done

        a=`ls -lrt $td/* |wc -l`        # Now taking word count of all the files copied.

        # Some more echo and priting.. just for aesthetics.. :)

        echo ; echo ; prnt "       **** COPIED $a FILES from \[$curdir\] to \[$td\] ****" ; echo ; echo

        echo ; echo ; ls -lrtha $td|head -10 ; echo ; echo

        exit            # Script exits after processing the files. You can replace exit with menu, to go back to menu again.
