The linux shell script judges whether the file or folder has a loop operation

If you change the script I wrote recently, you can use
3.sh all the data pointing to the directory like /data/test

#!/bin/bash
#set -x

#循环读取文件目录
for line in `cat /root/shizonghao/3.sh`
do
#判断当前文件是否存在
if [ ! -x "$line" ]; then
#如果不存在记录日志
  echo $line>>test.log
fi
done

#shell Determine whether the folder exists

#If the folder does not exist, create a folder
if [! -D “/Top” ]; then
mkdir -p /Topfi

#shell Determine whether the file or directory exists or has permission

folder="/Top"
file="/Top/test.txt"

The -x parameter determines whether $folder exists and has executable permissions

if [ ! -x “$folder"];thenmkdir"$folder”
fi

The -d parameter determines whether $folder exists

if [ ! -d “$folder"];thenmkdir"$folder”
fi

The -f parameter determines whether $file exists

if [ ! -f “$file"];thentouch"$file”
fi

-n judge whether a "variable" has a value

if [ ! -n “$file"];thenecho"The$ file variable is empty!"
exit 0
fi

Determine whether the string content of two variables are the same

if [ “$file1"="$file2” ]; then
echo “$file1 equal $file2"elseecho"$file1 not equal $file2”
fi

#!/bin/sh

Description: Determine whether the file exists

myPath="/Top"
myFile="/Top/access.log"

The -x parameter here determines whether $myPath exists and has executable permissions

if [ ! -x “$myPath"];thenmkdir“$ myPath”
fi

The -d parameter here determines whether $myPath exists

if [ ! -d “$myPath"];thenmkdir“$ myPath”
fi

The -f parameter here determines whether $myFile exists

if [ ! -f “$myFile"];thentouch"$myFile”
fi

Other parameters include -n, -n is to determine whether a variable has a value

if [ ! -n “$myVar"];thenecho"$ myVar variable is empty!"
exit 0
fi

Determine whether the content of the $file string is the same as "123123"

if [ “$file1"="123123"];thenecho"$file1 equal $file2"elseecho"$file1 not equal $file2”
fi
