Create and write file in single Linux/macOS command

If you want to create a fine and write to it in a single command you can do it in various ways, one of the way is to use the echo command and use > redirect the text to a file, but doing so the file will be created and echoed text will be written to the file.

bash $ echo "This will be written to the file" > myFile.txt

bash $ cat myFile.txt
This will be written to the file

You can in this way also redirect the output of a command to a file.

bash-3.2$ cd /
bash-3.2$ ls > /Users/code2care/Desktop/myFile.txt

bash-3.2$ cat /Users/code2care/Desktop/myFile.txt
