15+ Terminal Commands Every Developer Must Know

Whether you just learning programming or you have been doing it for decades, one thing is for sure. You need to know how to navigate the command line. This is especially true if you ever need to access a server since you will only ever have access to a command line interface.

">" is not the pipe operator. it is the redirect operator. ">>" is redirect and append. "|" is the pipe and it means take STDOUT of the previous program and give it to STDIN of the next program.

Tip: to re-run the last command with sudo permissions, instead of typing it again, just type "sudo !!"

[@kvetoslavnovak423]

Thank you. It would be great to mention the abbreviations meaning as well. Easier to remember the commands. pwd = Print Working Director, ls = List, sudo = Super User Do etc. PS: Touch command refers to a Michelangelo’s Creation of Adam painting I guess.

[@mobbs8229]

but then your insightful comment put the cherry on top! thank you!

[@Chalisque]

I think touch's original intended meaning was just to change the modification/access time of a file, but then, as programmers do, they ask what is the most useful behaviour when touch is given a non-existent file: either 'file not found' or 'create a zero-length file', and the latter won out.

[@calvinwilson3617]

Command line can be confusing, but just remember, all it is doing is running an executable with the name that you put for. The computer keeps an internal list of accepted commands, this is based on you environment variables which are automatically included during installation. Because the executable can only accept text through the command line you just seperate your parameters in a predefined way after the executable name.

[@arturomedina2055]

Doing a video about this topic was a great idea. 👍

[@Chalisque]

One thing where the CLI shines is your ability to define your own shorthands. These could be aliases, or functions, or indeed other scripts written in either bash or python or perl or whatever.

[@edgarasben]

"history" is another great command to show a list of all previously typed commands.

[@fregattkapitany2608]

A great summary of the basic commands for the command line! On windows10 in gitbash the man command is not found and cd or cd ~ always change to the home directory not to the one visited previously.

Well i've been using Linux (Archlinux with AwesomeWM) for almost a year now, and i don't want to go back to windows. I use linux+zsh so it's pretty easy to set it up your liking, and fzf could really come in handy if you want to make custom script and z can take your anywhere you've been, just type "z Project" and it will take you to your last "Project" folder no matter how long the path is, you don't even need to type "Project" just type "Proj" "ject" or any it will take you to the last directory with that keyword. Seriously if you haven't tried doing web development in linux TRY IT, it could save you a lot of time, though the time to master it might not be short, though some distro like Mint, Zorin, Pop OS give a Windows like experience so it's a good way to start. If you're already using linux then try switching to Window Managers instead of Desktop Environment (Gnome/KDE), make your own workflow and keybinding since it's gonna be easier to remember them if you're the one who make them.

[@Alex-bc3xe]

So touch is not a weird command, the purpose of touch is to update the date of a file with current time you can see in the modified property. People use touch to create files as a trick cause if there is no such file to update the time is creating a new one. Always ask the whys don't just do it cause everybody does it without knowing why.

You are probably using PowerShell on Windows? It knows the "ls" command ( sort of ), but not the same options as the Linux equivalent. Just typing "ls" gives a similar output as "ls al" on the Linux command line.

PowerShell is the cancer of programming languages! JavaScript is the herpes.

A space had slipped in between the / and * CTRL-C “guys, don’t stop anything or it won’t start, I’m gonna fetch last nights tape and restore my Fucking blunder!” The great thing with Unix is, as long as it’s running it keeps running without /etc Configs.
