How to make file executable

Suppose you have create a run.sh file and you want to be able to run it with bash. In the file, the first line should be like this:

1
#!/bin/sh

or like this:

1
#!/bin/bash

Then in the folder with your file run this command to add execute rights to the file:

1
chmod u+x ./run.sh

Finally, you can run this file like this:

1
./run.sh

Hide/show hidden files

The easy way

Since the release of macOS Sierra, when in Finder, it is now possible to use the shortcut:

1
CMD + SHIFT + .

Press once to show hidden files and again to hide them.

The long way

  • Open Terminal found in Finder > Applications > Utilities.
  • In Terminal, paste the following and press Return:
    1
    defaults write com.apple.finder AppleShowAllFiles YES|NO
  • Hold the ‘Option/alt’ key, then right click on the Finder icon in the dock and click Relaunch.

Beginning with Apple macOS X 10.13, High Sierra blocks by default starting of applications that were not downloaded by authorized by Apple way, not via AppStore or from unauthorized developers that had not paid the Apple Developer certificate. You need to delete attributes that were attached to the files during download.

From your terminal run the following commands:
