Unix/Linux bash shell script FAQ: How do I prompt a user for input from a shell script (Bash shell script), and then read the input the user provides? Answer: I usually use the shell script read function to read input from a shell script. Here are two slightly different versions of the same shell script. Example-1: Use bash getopts with single argument. In this sample script we will take single argument as an input to our script using getopts. The script currently only supports -h as input argument which will show the usage function. Jan 03, 2020 I'm running Catalina, 10.15.2, which uses the new zsh shell as a default.

There are command line flags (or 'switches') that Chromium (and Chrome) accept in order to enable particular features or modify otherwise default functionality.

Current switches may be found at http://peter.sh/examples/?/chromium-switches.html

It is important to note that some switches are intended for temporary cases and may break in the future.

Note that if you look at chrome://flags to see if the command line option is active, the state might not be accurately reflected. Check chrome://version for the complete command line used in the current instance.

Windows

1. Exit any running-instance of Chrome.
2. Right click on your 'Chrome' shortcut.
3. Choose properties.
4. At the end of your 'Target:' line add the command line flags. For example:
   • --disable-gpu-vsync
5. With that example flag, it should look like below (replacing '--disable-gpu-vsync' with any other command line flags you want to use):
   chrome.exe --disable-gpu-vsync
6. Launch Chrome like normal with the shortcut.

macOS

1. Quit any running instance of Chrome.
2. Run your favorite Terminal application.
3. In the terminal, run commands like below (replacing '--remote-debugging-port=9222' with any other command line flags you want to use):
   
   /Applications/Chromium.app/Contents/MacOS/Chromium --remote-debugging-port=9222
# For Google Chrome you'll need to escape spaces like so:
/Applications/Google Chrome.app/Contents/MacOS/Google Chrome --remote-debugging-port=9222

Linux

1. Quit any running instance of Chrome.
2. Run your favorite terminal emulator.
3. In the terminal, run commands like below (replacing '--remote-debugging-port=9222' with any other command line flags you want to use):
   
   chromium-browser --remote-debugging-port=9222
google-chrome --foo --bar=2

V8 Flags

V8 can take a number of flags as well, via Chrome's js-flags flag. For example, this traces V8 optimizations:

To get a listing of all possible V8 flags:

Browse the V8 wiki for more flags for V8.

Android

Visit 'about:version' to review the flags that are effective in the app.

If you are running on a rooted device or using a debug build of Chromium, then you can set flags like so:

You can also install, set flags, and launch with a single command:

For production build on a non-rooted device, you need to enable 'Enable command line on non-rooted devices' in chrome://flags, then set command line in /data/local/tmp/chrome-command-line. When doing that, mind that the first command line item should be a '_' (underscore) followed by the ones you actually need. Finally, manually restart Chrome ('Relaunch' from chrome://flags page might no be enough to trigger reading this file). See https://crbug.com/784947.

ContentShell on Android

There's an alternative method for setting flags with ContentShell that doesn't require building yourself:

1. Download a LKGR build of Android.
2. This will include both ChromePublic.apk and ContentShell.apk
3. Install ContentShell APK to your device.
4. Run this magic incantation

Macos Bash Prompt For Input With Default Settings

This will launch contentshell with the supplied flags. You can apply whatever commandLineArgs you want in that syntax.

Android WebView

This is documented in the chromium tree.

Chrome OS

1. Put the device into dev mode, disable rootfs verification, and bring up a command prompt.
2. Modify /etc/chrome_dev.conf (read the comments in the file for more details).
3. Restart the UI via:
   sudo restart ui

Note

Using Anaconda in a commercial setting? You may need to purchase a license to stay compliant with our Terms of Service. This can be accomplished through Anaconda Commercial Edition, Anaconda Team Edition, or Anaconda Enterprise. If you have already purchased Commercial Edition, please proceed to the Authenticating Commercial Edition section after completing your installation here.

Haven’t purchased Commercial Edition yet? Visit https://anaconda.cloud/register to get started.

You can install Anaconda using either the graphical installer (“wizard”) or thecommand line (“manual”) instructions below. If you are unsure, choose the graphical install.

macOS graphical install¶

1. Download the graphical macOS installer for your version of Python.

2. RECOMMENDED: Verify data integrity with SHA-256.For more information on hashes, see What about cryptographic hash verification?

3. Double-click the downloaded file and click continue to start the installation.

4. Answer the prompts on the Introduction, Read Me, and License screens.

5. Click the Install button to install Anaconda in your ~/opt directory (recommended):

6. OR, click the Change Install Location button to install in another location (not recommended).

   On the Destination Select screen, select Install for me only.

   Note

   If you get the error message “You cannot install Anaconda in this location,” reselect Install for me only.

7. Click the continue button.

8. Optional: To install PyCharm for Anaconda, click on the link to https://www.anaconda.com/pycharm.

   Or to install Anaconda without PyCharm, click the Continue button.

9. A successful installation displays the following screen:

10. Verify your installation.

Using the command-line install¶

Macos Default Input Source

Use this method if you prefer to use a terminal window.

Macos Bash Prompt For Input With Default Password

1. In your browser, download the command-line version of themacOS installer for your system.

2. RECOMMENDED: Verify data integrity with SHA-256.For more information on hash verification, see cryptographic hash validation.

   • Open a terminal and run the following:

   Note

   Replace /path/filename with your installation’s path and filename.

3. Install for Python 3.7 or 2.7:

   • For Python 3.7 enter the following:

   • For Python 2.7, open the Terminal.app or iTerm2 terminal application and then enter the following:

   Note

   Include the bash command regardless of whether or not you are using the Bash shell.

   Note

   Replace ~/Downloads with your actual path and Anaconda3-2020.02-MacOSX-x86_64.sh with actual name of the file you downloaded.

4. The installer prompts “In order to continue the installation process, please review the license agreement.”Click Enter to view the license terms.

5. Scroll to the bottom of the license terms and enter yes to agree to them.

6. The installer prompts you to Press Enter to confirm the location, Press CTRL-C to cancel the installationor specify an alternate installation directory. If you confirm the default location,it will display PREFIX=/home/<user>/anaconda<2or3> and continue the installation.

   Note

   Unlike the graphical install, installing the shell file will place it in ~/anaconda<2 or 3> by default,not ~/opt. This is due to limitations with installing .pkg files on macOS Catalina.

   Installation may take a few minutes to complete.

   Note

   We recommend you accept the default install location. Do not choose the path as /usr for theAnaconda/Miniconda installation.

7. The installer prompts “Do you wish the installer to initialize Anaconda3by running conda init?” We recommend “yes”.

   Note

   If you enter “no”, then conda will not modify your shell scripts at all.In order to initialize after the installation process is done, first runsource<pathtoconda>/bin/activate and then run condainit.

   Note

   If you are on macOS Catalina, the new default shell is zsh.You will instead need to run source<pathtoconda>/bin/activatefollowed by condainitzsh.

8. The installer displays “Thank you for installing Anaconda!”

9. Optional: The installer describes the partnership between Anaconda and JetBrains andprovides a link to install PyCharm for Anaconda athttps://www.anaconda.com/pycharm.

10. Close and open your terminal window for the Anaconda installation to take effect.

11. To control whether or not each shell session has the base environmentactivated or not, run condaconfig--setauto_activate_baseFalseorTrue. To run conda from anywhere without having the base environmentactivated by default, use condaconfig--setauto_activate_baseFalse.This only works if you have run condainit first.

    Note

    condainit is available in conda versions 4.6.12 and later.

12. Verify your installation.
