Question

我一直在尝试创建一个shell脚本，它将文本文件一个接一个地分割成一个整个文件夹，然后将每个拆分块存放到另一个指定的文件夹中。

这是我到目前为止所知道的，我知道它可能很笨重（之前从未尝试过写过.sh）：

#!/bin/bash
#File Split Automation

echo "Usage: split [Folder w/ Input] [Folder For Outputs] [Options] [PREFIX]
  Options: -b [sizeMB]: Split by size
  -l [No. of Lines]: Split by Lines
  If No Output Folder is Defined Default is Set To: /Desktop/splitter-parts
  If No Options Are Selected Default is Size=100MB"

inputdirc=$1
outputdirc=$2
spltion=$3
meastick=$4
prefixture=$5

if [ -d $1 ]
then
    echo "You Picked The Folder $1 To Split Files From"
    ls $1
else
    exit
fi

if [ -d $2 ]
then
    echo "Please Confirm Folder Path For Output $outputdirc"
else
    cd /root/Desktop/
    mkdir -p splitter-parts
fi



read -t 10 -p "Press Enter Or Wait 5 Sec. To Continue"


cd $2

for swordfile in $( ls $1); 
do
command -p split $3 $4 -a 3 -d $swordfile $5

done

你看到的任何错误？因为我没有得到我想要的输出，但是当我在split-command字符串中有一个文件和一个文件夹时它运行正常。

EDIT ::::

抱歉，我道歉。只是领先一步。

这是我在运行时看到的：

root@kali:~/Desktop/Wordlists# ./splitter.sh '/root/Desktop/Wordlists'               '   /root/Desktop/Untitled Folder' s 100MB

If No Options Are Selected Default is Size=100MB

就我应该看到的情况而言，我还没有那么远，显然我错过了一些步骤。

快速重写，并附上一些注意事项：

#!/bin/bash
#File Split Automation

usage="Usage: split [Options] [Folder w/ Input] [Folder For Outputs] [PREFIX]
  Options: -b [sizeMB]: Split by size
  -l [No. of Lines]: Split by Lines
  If No Output Folder is Defined Default is Set To: /Desktop/splitter-parts
  If No Options Are Selected Default is Size=100MB"

split_opt="-b 100MB"
while getopts hb:l: opt; do
    case $opt in
        h) echo "$usage"; exit ;;
        b) split_opt="-b $OPTARG" ;;
        l) split_opt="-l $OPTARG" ;;
    esac
done
shift $((OPTIND - 1))

if [[ $# -eq 0 ]]; then
    echo "$usage"
    exit 1
fi

inputdirc=$1
if [[ -d $inputdirc ]]; then
    ls $1
else
    echo "no such directory: $inputdirc" >&2
    exit 1
fi

if [[ -n $2 ]]; then
    outputdirc=$2
else
    outputdirc=/root/Desktop/splitter-parts
fi

prefixture=$3

mkdir -p "$outputdirc"
cd "$outputdirc"

for swordfile in "$inputdirc"/*; do
    command -p split $split_opt -a 3 -d "$swordfile" $prefixture 
done

注意：

您通常希望引用所有您的变量。这是导致错误的原因，因为名称中有一个带空格和方括号的文件。
我没有在split命令中引用一对，因为我特别希望shell对值执行word splitting
由于选项是可选的，因此请使用getopts来收集它们。
将位置参数存储在变量中，但您继续使用位置参数。选择一个或另一个。
