Make your own linux command??

To achieve that you can simply create bash script and put it in one of paths folders.

Script:
#!/bin/sh clear && ls

Save it as command_name.sh file and change its permissions to 755 (chmod 755 filename), then in your terminal echo $PATH variable to see in which folders you can put your file to act like “command”, after that just move your script to one of folders in $PATH variable, e.g. /usr/local/bin

You may also need to use sudo command sometimes during this process. To call that script file you only have to write command_name from command_name.sh

Thanks a lot @souvarine :) I jsut did it. Do you know why wen I do the normal command ls some files appear with diferent colors but when I do it with the command that I made the files are all of the same color

@lexostras, to colorize the output when calling ‘ls’ from script, you should add –color=always parameter, then your command shoud look like this:
clear && ls --color=always

Problem is that “ls” has different default values when called directly from terminal emulator and from script file.

Another option is using ‘alias’:
alias cls='clear && ls'
You can add this to your ‘.bashrc’ if you like.

If you look in ‘.bashrc’, you’ll also see why doing it with that little script doesn’t work in the same way. The command ‘ls’ is made an alias for ‘ls –color’ (or something similar), but only when running interactively, which a script is not.

thank you @dloser do you know a good reference to make scipts like that one that I am making because I am having a lot of fun here :) and I tried out the alias cls='clear && ls'
but when I restart the teminal It does not work and when I put your code in the file that I made for the command, It does not work. Do you know a way to change that??

Like he said you need to put it in your .bashrc (or .profile/.cshrc/.zshrc depending on your shell).

do note though, that colors are done by ansi escape codes and might cause problems when piping

ok thanks @nakee

Hope this helps you in setting it up.

@tl0tr I don’t get how people can stand those videos, it’s waisting 15 minutes on something you can find in 2 scanning some tutorials in google

@nakee : I am a visual learner. That’s how I learn. I just posted the video cause it might help @lexostras in answering the questions that he/she has.

@tl0tr but reading is also visual learning:)
Anyhow it was not meant as attack, I’m just honestly curirous at how is it better than reading

@nakee , everyone is different. I am more like @tl0tr too. I learn more on youtube than any other site. For me learning python was on youtube, and not codecademy.com . Google was only to find additional information :D

code academy is boring I learned from crash crush on python:)

Hmm I also like to watch videos sometimes, but till now I found that when you go deep into a topic the best source of info is still only written.

Thanks to all of you guys I finaly made it thx a lot :)
