Hello. I hava homework for university but i cant do it and i need a little help if someone can help me 
I have to do a linux shell script.
Write a script that does the following:
- Check if there is a directory in / home with myDir name.
If not, it creates it. - In the directory it creates a new myFile file, checking if the user,
triggered the script, has write permissions on that file, if it does not, it outputs
Error message. - If there is, record the names, faculty numbers, and group of the file in the file
team members. - Shows the contents of the file on the screen by numbering the rows and how many
times the script has been started so far.
#!/bin/bash
if (! dir -d myDir); then
sudo mkdir myDir
else echo "The folder already exist!"
fi
cd myDir && sudo touch myFile2
I done 1. but on the 2. when i create the file i dont know how to chek for permissions and how to do it can someone help me please ?
