5 Linux commands that every developer must know

A developer typically uses hundreds of Linux commands in a day to day work. But some of the Linux commands can be long and it might take a little more time to write and execute. I have composed a list of 5 Linux commands which can improve productivity as well as can save the time of a developer.

In the video, I will be talking about the following Linux commands -

1. sudo - If you forget to use the sudo before running any Linux command then in such case you can simply run the sudo !! and it will re-run your previous command with sudo.
2. yes | your_cmd - It is very often that you need to download or install a certain package onto your Linux machine where you need to provide manual confirmation every time. So to save some of your time you can simply add "yes |" followed by your Linux command and after that, you no longer need to provide manual confirmation.
3. hstr - "hstr" utility can be really useful to search any Linux command from the previous history. Although you have "history" command with "hstr" you can navigate between the history commands with the help of the navigation arrow key
4. glances - "glances" utility can be really useful to view CPU stats in the form of CPU usage, memory usage, disk usage, and the top processes.

▬▬▬▬▬▬ ⭐️ Time Stamps ⭐️ ▬▬▬▬▬▬
0:15 - sudo !!
01:40 - yes | your_cmd automatically answer y/yes in bash script
03:30 - hstr command line utility that brings improved bash / zsh command completion from the history
06:25 - Glances tool offers more information about system performance than other sysadmin monitoring tools

Actually a substitute to installing hstr, when you run $ history you see a number(index) and the command(value), therefore you can simply re-run that command by typing ![index] (e.g. !134).

Awesome video though, keep up the good work! :)

fun fact... if you type:

sudo ls /usr/bin | cat > text.txt

you can see all the commands available on your unix/linux system.

if you do a:

man <command>

you can then see what that command does..
