Linux, which is an operating system, requires some network commands that direct it to perform certain tasks or show certain details. Generally, the Linux commands that we give to the operating system to perform the requested tasks are giving commands. These commands are typed in the Linux terminal and given individually, which can consume more time and is comparatively difficult.
Bash scripting or Shell scripting is a programming system where we create a specific file, and on an orderly basis, we place one after the other Linux command, we place these commands in one single file. Then, the specific file is transformed in the form of scripts. By doing so, we can easily activate or command our shell interpreters to execute the commands altogether.
What are some useful bash scripts to make?
Bash scripts have simply made the whole command-giving process much easier, and as a result, the lives of Linux system operators have become very easy and smooth. Today, various sets of commands can be used in the best possible way. These bash scripts are used for various significant reasons, such as running multiple commands collectively, customizing administering tasks, or executing a bash command. So, someone who wants to learn operating Linux commands must make sure to learn bash scripting. Following are some bash scripting according to the requirement.
Useful bash scripts Linux
The following list of scripts makes the task run smoothly. Tasks that are generally not done so efficiently in my manual process are done here with some simple bash scripts.
- ls | we -w
This command is used to count the number of files that are mentioned in the directory. To execute this command, the user needs to go to the directory to count the files. Next is to open up the Linux terminal and type the above-given command to run the task.
- ls -Rt
This command is used to list the directories. This listing you are looking for is in a specific order of the last edited date. To do so, open the directory and, in the Linux terminal, write the above-given command.
- ls –sort=time
This bash script is used to sort the last edited files in a systematic or chronological order. To do so, visit the directory and, in the terminal type, the above command to execute the task.
- Ls; cd.
With this specific command given above, you can easily run multiple commands in a single line. To do so, open the space where you’re going to type your command, namely the Linux terminal. Type command1; command2; (you can choose any number of commands to write).
Once, it used to be such a troubling and time-consuming task for Linux system administrators to run the same tasks every day. Today, the expert developers have successfully made useful bash scripts for Linux system administrators.
These shell scripts are used to execute some of the basic commands such as hostname, DNS information, network information, online user accounts information, history of the logged user accounts information, and used memory. The free space available information tells an individual’s public IP address, details of process usage and disk usage, and many more often-used scripts.
Like above, learning or gaining knowledge of scripting is also useful; bash scripts for mac and useful bash scripts for web developers need equal attention and an urge to be understood.
Q.1 How are bash scripts useful?
A.1 Bash scripts are significantly used in tackling various basic tasks. These are useful for anyone who is working or operating a Linux system as an administrator. Being an admin means that you will have to be quick at resolving hundreds of system-related issues. Knowing the commands is one thing, but using it fluently in the Linux terminal is another.
These commands are often run one by one, whereas, being an admin, the operator must be efficient in running multiple commands simultaneously and in the same line. For this very purpose, developers have come up with ‘Bash scripting or Shell scripting. This method is beneficial as it makes the whole processing task go smooth and fast. Through this, the admin can assemble the commands given to the system in a single file. This file is further made into a script, and the commands are given out quickly.
Q.2 How are bash and python scripts useful for a DevOps engineer?
A.2 Along with many other scripting processes, Bash Scripting and Python Scripting are beneficial for a DevOps engineer.
Bash Scripting Even today, many DevOps developers generally prefer to use shell scripting to develop various operating systems and develop various software applications to operate it as per their needs or requirement easily. It comes with a very satisfying power and goes beyond its limitation to perform the execution tasks.
Python Scripting Just as DevOps engineers prefer Bash Scripting, they also look at the wide range of usability attached with python scripting. This form of scripting comes with many uses, such as building cloud infrastructure projects, supporting various web applications, and efficiently be used for almost all purposes. So, this language platform is listed as one of the top considered options and more often used by the DevOps engineers as it comes with a wide range of scripting usability options.
This article discussed bash scripts; what are these bash scripts used for, various useful bash scripts that make the task easier and quicker for the Linux operator admin, and bash scripts used to execute systems? Linux administrator, mac, or web developers. We also discussed some of the basic questions, which are asked frequently while anyone is learning bash scripting.
