How to find whether a directory or file exists in Linux

Two methods: find command or shell script.

1. Find command

(1) find is a common method for finding files under Linux.

(2) find syntax:

find  [指定查找目录]  [查找规则]  [查找完后执行的action]

(3) For example: find /tmp -name wa* -type l, it is to find a symbolic link named starting with wa under /tmp. document. To find it means to exist.

2. Shell script

(2) Example: Edit a script to determine whether the file exists.

vi  t.sh
#!/bin/bash
if  [ -e /temp/test.log ]；then   //这里是判断语句，-e表示进行比较结果为真则存在
echo "文件存在"
else
echo "文件不存在"
