I want to do some simple calculations with variables in an
script.sh, in the same directory there is a folder called
New Folder2. So, I want to enter into the folder and save a text file.
The script is the following:
#!/bin/bash foldername='New Folder' number=1 number=$number+1 cd $foldername$number echo '$number' > number.txt
But then I only get the file
number.txt in the same directory
1+1 not the actual sum. What should I do?
