Question

此脚本尝试将文本文件复制到另一个目录中。我不明白为什么我遇到这个问题： ./move_in.sh：第36行：ls：找不到命令在我添加if语句之前它一直正常工作。

update_file=pwd
echo ""
echo "You can move a text file from your PC into the repository"
echo ""
echo "You need to know where is your text file"
cd /
ls
times=1
echo ""
echo "Where is your text file?"
read directory

while [ -d $directory ]
do
echo $times
if [ $times == 1 ]
then
LAST=$directory
fi

if [ $times != 1 ]
then
LAST=$PATH/$directory
fi

cd $directory
ls
echo ""
echo "Where is your text file?"
read directory
PATH=$LAST
echo $PATH
times=$((times + 1))
done

PATH=$PATH/$directory
echo $PATH
open $PATH
cp $PATH /\$update_file
echo "You found the text file!"
exit 0

我想在进程完成时获得文件的完整路径，这就是我使用LAST和PATH的原因，并且我将它们均衡。

Answer 1

您正在删除$ PATH使用PATH = $ PATH： ls不是内置命令，因此必须在PATH环境中

ls：命令未找到BASH
