I use cygwin console for windows, but when I type clear, it says:
command not found
How can I clear the console?
You may use Ctrl + L
On Linux the clear command would be cls, but this command doesn't seem to work in cygwin. (At least not when I tested it.)

I am trying to make run a script for webscraping. However, I feel the problem could be that I keep running the written script in the wrong console.
So far I could not really understand the differences between the consoles cmd and Anaconda Prompt. Anaconda Navigator looks rather like an administrative tool, but it seems still to make a difference for my code whether I use a terminal from there or not. Could anyone elaborate on that?
Much appreciated
cmd: command-prompt, that used to run our python script, especially for scripts with .py extension. Besides that, we can used to install python library
Anaconda Prompt: almost similar to cmd. But usually we used to open jupyter notebook or other console on Anaconda Navigator.
Anaconda Navigator: a GUI desktop application that is included in the Anaconda installation package. Through Anaconda Navigator, programmers can easily run and manage Conda packages, environments and channels without the need to use command prompt commands. Anaconda Navigator can search for packages in the anaconda cloud repository.
So, the difference depends on what we want to do. You can't judge the problem arises because of the wrong console. It depends on the error message that appears.
Suggestion: read the error message, and analyze or find a way to solve the problem
After installed the toolchain of xv6 needed on archlinux, following Tools Used in 6.S081 , I run the riscv64-unknown-elf-gcc --version, but my command line shows zsh: command not found: riscv64-unknown-elf-gcc, how can I do next?
In my archlinux, use the riscv64-linux-gnu-gcc command to compile, in macOS I use riscv64-unknown-elf-gcc, maybe try the first one, Or try typing risc and then pressing the tab key, maybe the shell will help you complete the rest of the command
On Windows, default terminal for Atom's Platformio-Ide-Terminal is Powershell (at least, that is what I get without any configuration).
I would prefer a terminal using unix-type commands. I already have MINGW and CYGWIN installed.
How can I avoid opening a Powershell and opening another terminal type instead?
Set the default shell in:
Edit>>Settings>>Packages>>Platformio Ide Terminal>>Settings>>Shell Override
You can use the git's bash as proposed here as you probably already have git installed.
C:\Program Files\Git\bin\bash.exe
Step by Step Solution
Go the Setting-> Packages -> In Search Bar, search for the platformio.
Open platformio and go to Shell Override Option.
Put the following line as per as your Terminal Requirement
For cmd- C:\\WINDOWS\\System32\\cmd.exe
For Power Shell- C:\\WINDOWS\\Sysnative\\WndowsPowerShell\\v1.0\\powershell.exe
For bash- C:\\Program Files\\Git\\bin\\bash.exe or C:\\Windows\\System32\\bash.exe (depending on how you install the bash). Be Sure, that you have already install the bash into your computer.
Now, you can integrate bash, cmd, git bash, Power Shell into Atom using platformio as terminal.
For CYGWIN users, the bash executable from the following location has proved useful for setting the shell override Settings >> Packages >> Platformio Ide Terminal >> Settings >> Shell Override
C:\cygwin64\bin\bash.exe
If you are now using Ubuntu for Windows 10 (downloaded from the app store), you can change it to that as well.
Ubuntu gets installed in Windows' PATH by default, so just change the default shell to:
ubuntu.exe
That's it. Just remember that to get to your code, cd to /mnt/(driveletter)/wherever/your/files/sit.
For someone who still can't get this to work because your git bash is installed in AppData. This worked for me.
C:\Users\saurabh\AppData\Local\Programs\Git\bin\bash.exe
I have googled it and some says type cls then enter.
But I have tried all :
"cls .cls cls; .cls;"
But no luck
Am I wrong or there is no cls command in sqlite3?
To execute CLS command in the SQLite3 shell you need to do this: .shell cls
As simple as that, .shell args... allows you to execute CMD commands in the SQLite3 shell.
There is no clear command in the SQLite command-line client.
But, if you're on a unix-based system (includes Mac OS X) you can use: Ctrl+L
Update:
While my answer is quick and simple, if you're on a compatible OS, make sure you also check out ivan0590's answer about the .shell command. Definitely a "good to know" as well.
Depending on the shell.
In Ubuntu -> .shell clear
On mac or Unix Operating systems:
.shell clear
.shell cls will always work(C'mon, if you are in windows🙃). If you are using Linux/Unix/Mac OS, try using .shell clear
For Windows:
.shell cls
For Linux and Mac:
.shell clear
I just downloaded the Sqlite3 command line shell for windows (http://www.sqlite.org/download.html). However when I try to run the executable in Cygwin it does not load and just hangs.
The Sqlite3 shell itself works as if I browse to it in Windows explorer it runs or if I open it in cmd it runs. How do I get it to work with Cygwin?
Cygwin currently doesn't work well with interactive native programs. It has to do with the way the Cygwin terminal code works, in order to provide expected POSIX semantics to Cygwin programs.
Therefore, your best bet is to use Cygwin's own SQLite package.
If you absolutely must use the native sqlite3.exe, you'll have use cmd.exe to run sqlite3.
