2. Shell script

(1) in Automatic identification is often required in automatic processing of files. The following script determines whether test.log exists. If it exists, it will display that the file exists. Otherwise, it will display that the file does not exist.

(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"
fi

Save and exit

Execute:

sh t.sh
