Check if file exist Linux bash
提问by Painguy
So I'm trying to check if a file exists or not and then the script is supposed to do something if it does. The problem I'm having is actually getting it to recognize that something is actually there.
因此，我试图检查文件是否存在，然后脚本应该执行某些操作（如果存在）。我遇到的问题实际上是让它认识到确实存在某些东西。
if [ -e /temp/file.txt ]; then
echo "file found!"
sudo cp -r temp/* extra
else
echo "file not found! Creating new one..."
./create.sh
fi
below is an example of the files in the directory I'm testing. they are clearly there, but for some reason I can't get the script to see that. what am I doing wrong?
下面是我正在测试的目录中的文件示例。他们显然在那里，但由于某种原因，我无法让脚本看到这一点。我究竟做错了什么？
nima@mkt:/docs/text$ ls -a temp
. .. more file.txt file2.txt

You are using absolute paths in your test while you should be using relative paths:
您在测试中使用绝对路径，而您应该使用相对路径：
if [ -e ./temp/file.txt ]; then

/temp/file.txtvs /docs/text/temp/file.txt?
/temp/file.txt与/docs/text/temp/file.txt?
回答by Sven
You script looks in /tempwhile you are looking in /docs/text/temp
您在查看时脚本/temp会查看/docs/text/temp
