Mac command not found solution

MacBook Air command not found. This may have been caused by modifying the Profile when configuring Java Path.
: ls CD, vim, sudo, man command not found

1. First, enter commands so that you can use commands such as Vim temporarily

export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/X11R6/bin

Then open ~/.bash_profile

vim ~/.bash_profile

2. Add PATH

export PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:${JAVA_HOME}:${JAVA_HOME}/bin"

3. Restart Profile

source ~/.bash_profile

Exit Terminal, open it again, and type Vim to see if it works

Batch modification of file names on MAC Linux rename command line

[rename] [rename] [rename] [rename] [rename] [rename]

zsh: command not found: rename

So use Homebrew to install it first:

➜  ~ brew install rename

After that, you can directly use a simple one-line command to change the name of multiple files. The general format is as follows:

➜  ~ rename 's/old/new/' *.files 

Ex. :
Change the prefix of batch PNG files from ‘ic_’ to ‘ic_setting_’ :
(ic_launcher.png -> ic_setting_launcher.png)

➜  ~ rename 's/ic_/ic_setting_/' *.png 

Modify part names of batch files:
(ic_setting_launcher.png -> ic_launcher.png)

➜  ~ rename 's/_setting//' *.png 

Supplement:
You can also use :
to change the first five letters to XXXXX (note ^… It’s five.

for i in `ls`; do mv -f $i `echo $i | sed 's/^...../xxxxx/'`; done

Usage is almost the same, the rest is up to us to flexibly use.

How to disable icloud drive on Mac?

ICloud Drive is a very useful feature that makes it easy to share files and documents between your devices (including other Macs, iPhones, and iPads) by automatically synchronizing and copying files between devices, so you should only disable iCloud Drive if you don’t have it enabled. So how to disable the iCloud drive on the Mac, there is a need for friends to welcome the reference!

Please note that this is disabling iCloud Drive completely on the Mac, not just disabling the iCloud desktop and documents that only store these two directories in iCloud.
Before attempting this step, make sure your Mac has a valid Internet connection.
The specific methods are as follows
1. Go to the Apple icon in the menu bar and select “System Preferences”.
2. Select “iCloud Settings”.
3. Uncheck the iCloud drive next to this check box.

4. Make sure to disable the iCloud drive and remove the iCloud files from your Mac.
You now have two options to choose what you want to do with your iCloud file.
Keep a copy – This keeps a downloaded copy of the iCloud files on the Mac. This option is recommended if you want to access the files offline later. This option works for most Mac users.
Delete from Mac – Selecting this option will remove all files from the iCloud drive on your Mac, and you will no longer be able to access these files on your computer.

5. Once you have selected the desired options, exit System Preferences on your Mac.
When you close the iCloud drive on your Mac, you’ll notice that the iCloud options disappear from the sidebar of the Finder, as well as from the Dock or anywhere else on your system. This is because you have completely disabled iCloud Drive from your Mac. You will not be able to save, copy, move, or upload files from your Mac on your iCloud drive.
To re-enable iCloud Drive, go back to System Preferences and select the iCloud Drive box.

How to open an app from an unidentified developer

How to open an app from an unidentified developer
You can run apps that you’ve downloaded directly from the internet that aren’t registered with Apple. You just have to give the OK.

    After downloading an app from an unidentified developer, drag it to the Applicationsfolder. Select the app and right or control-click.   Click on Open. Click on Open again to confirm you want to complete the action.

Opening an app from unidentified developer with a right or control-click overrides Gatekeeper for that specific app. From now on, you’ll always be able to open it without having to go through the process again.
How to reinstate the Anywhere setting in Gatekeeper
If the thought of having to right or control-click to open apps from unidentified developers seems arduous and tiresome, you can turn back time with Gatekeeper and bring back the ability to open apps from anywhere. All it takes is a bit of coding in Terminal.

    Close System Preferences on your Mac. Open Terminal. Type the following command: sudo spctl –master-disable Hit enter on your keyboard. Enter your administrator password. Hit enter on your keyboard.

Gatekeeper’s “Anywhere” setting will now be restored. It will also be selected by default. You can confirm the changes by opening System Preferences and selecting Security & Privacy.

If you ever want to enable the macOS Sierra Gatekeeper settings again, type sudo spctl –master-enable into Terminal.
