How to write Shell scripts with ChatGPT

Because I have to use the machine to do stress testing before I get off work recently, I am more interested in shell scripts during this time. It is very convenient to write shell scripts with chatGPT.

The following are some cases

For example, I need to write a batch process: write a batch process to create 20 folders under the current folder, and each folder contains a text document. The first sentence of the text document is hello word. Save the following code as a create_folders.bat file, and run the batch file in the desired folder to complete the operation
.

@echo off

setlocal enabledelayedexpansion

for /l %%i in (1,1,20) do (
    set folder=Folder_%%i
    mkdir !folder!
    echo hello world > !folder!\text.txt
)

echo 20 folders with text files have been created.

Isn’t it very convenient~~

If you want to rename the folder, for example: write a batch to rename all folders under the directory to 1.2.3.4, etc.

@echo off

setlocal enabledelayedexpansion

set count=1

for /d %%i in (*) do (
    ren "%%i" "!count!"
    set /a count+=1
)

echo All folders have been renamed.

Follow the steps just now, create a new txt file, copy it in, save it, rename it and run it

However, I usually write scripts with the .sh suffix under Linux. The differences between them are as follows:

.sh and .bat are the suffixes of script files in different operating systems, and they have the following differences:

1. .sh suffix: .sh is the suffix of Shell script files, used in Unix-like systems (such as Linux, Mac OS). A shell script is a text file that contains a series of shell commands for executing commands and controlling the flow. Typically Bash or other shell interpreters are used to execute .sh script files.

2. .bat suffix: .bat is the suffix of the batch script file, used in the Windows operating system. A batch script is a text file that contains a series of batch commands for executing commands and controlling the process. When running a .bat script file, the system will call the cmd.exe interpreter to execute the commands in it.
   Below is a table comparing .sh and .bat script suffixes, including their syntax differences:

characteristic	.sh script	.bat script
suffix	.sh	.bat
operating system	Unix-like operating system (such as Linux, Mac OS)	Windows operating system
interpreter	Usually using Bash or other shell interpreter	Use cmd.exe interpreter
comment symbol	#	REM
variable declaration	use variable=valueformat	use set variable=valueformat
variable reference	use $variableor ${variable}method	%variable%How to use
Conditional statements	Use if, elif, else statement structure	Use if, else, goto and other statement structures
loop statement	Use for, while, until and other loop structures	Use for, if, goto and other looping structures
input Output	Use the echo command to output content, and use the read command to read user input	Use the echo command to output content, and use the set /p command to read user input
array	Support array declaration and operation	Arrays are not supported
file operation	Use cp, mv, rm and other commands to perform file operations	Use copy, move, del and other commands to perform file operations
Pipelines and Redirection	Use the pipe symbol`	和重定向符号>、>>`等
function definition	function_name() { ... }define function using	Define functions using :labelandgoto label
script execution permission	You need to add execute permission to the script file	No additional execute permissions are required

To sum up, .sh and .bat are the extensions of different types of script files used in different operating systems. .sh is used for shell scripts in Unix systems, and .bat is used for batch scripts in Windows systems.
