unable to run phyton

[mkamal-amohsin]

Hi all,

i recently installed ubuntu 20.04 desktop on my laptop. Found out that I can't run any phyton command, says command not found.

mus@mus-ONYX-G:/etc$ phyton --version
bash: phyton: command not found
mus@mus-ONYX-G:/etc$ phyton2 --version
bash: phyton2: command not found
mus@mus-ONYX-G:/etc$ phyton3 --version
bash: phyton3: command not found
mus@mus-ONYX-G:/etc$ whereis phyton3
phyton3:
mus@mus-ONYX-G:/etc$ whereis phyton2
phyton2:
mus@mus-ONYX-G:/etc$ whereis phyton
phyton:
mus@mus-ONYX-G:/etc$

but checking /usr/bin phyton existed:

lrwxrwxrwx 1 root root 16 Mei 11 15:45 python -> /usr/bin/python3
lrwxrwxrwx 1 root root 9 Mac 13 2020 python2 -> python2.7
-rwxr-xr-x 1 root root 3674216 Mac 8 21:02 python2.7
lrwxrwxrwx 1 root root 33 Mac 8 21:02 python2.7-config -> x86_64-linux-gnu-python2.7-config
lrwxrwxrwx 1 root root 16 Mac 13 2020 python2-config -> python2.7-config
lrwxrwxrwx 1 root root 9 Mei 10 01:55 python3 -> python3.8
-rwxr-xr-x 1 root root 5486384 Jan 27 23:41 python3.8

Running the same on Live usb also yields the same result. Anything that I'm missing?

Sadly the command line is strictly 'do what I say' (or rather 'type'), not 'do what I mean'. Typos like 'phyton' instead of 'python' (the 'h' comes after the 't', not after the 'p') will not be corrected automatically. Normally the 'command-not-found' handler of the shell should come up and print an educated guess about what you could have meant, but in this case it doesn't.

[tea for one]

You have transposed the h and y in python

phyton should be python

Thank you all for pointing this out. My ignorance amuses me.....

And us, but you aren't the the first person to do this. Learn to use "tab-completion" and most issues like this will not happen anymore.
https://github.com/jlevy/the-art-of-command-line -- tab-completion is 1000x harder to explain in words than to show/demonstrate. Type 2 characters for a command, then hit {tab}{tab}.

If there's only 1 command in the PATH that begins with those 2 characters, it will be filled in. If there are more, a list of possible commands will be shown.

In short, if you are typing more than 2 characters at a time+{tab}, then you are doing it the hard way.

Most CLI tools have a bash-completion file so options to the command can also be completed ... or at least input files. Look for videos to show this stuff and make it a habit to use.

Could make a symlink

Could make a symlink

or an alias

alias phyton='python'

but that would only work from bash in a shell, not inside scripts.

Thanks for tip. Will remember that from now on

My system insists on doing it the hard way

~$ py<tab>
py3clean      py3versions   pydoc3.8      pygettext3.8  pyjwt3        python3.8
py3compile    pydoc3        pygettext3    pygmentize    python3

~$ pyt<tab>

results in

 
$ python3

Am I doing something wrong?

Another tip regarding the terminal for those like myself who make typing errors. The terminal keeps a history of the commands we type. Pressing the up arrow key will scroll through them. The down arrow key will scroll the other way. Yes, we will see the wrongly typed commands but also those commands that we type correctly. It can reduce the opportunity for mistyping of commands.
