You can accomplish that by iterating a second list based on your first list through nested loops. This gets a little hard to follow when you're doing it as a one-liner, but it can definitely be done. Your nestedforloop gets executed on every iteration of the parentforloop. Be sure to...
Line 3starts the nestedforloop at zero. The value increments by one and ends at nine inclusively. Line 5prints the values from theforloops. The nested for loops through all numbers three times, once for each outer loop value. The output prints each number combination to the console and ent...
“for” loop in a sequence is said to be “nested”. Therefore, we have decided to use the “nested” for loops in Bash programming within our examples of today’s article. So, let’s start with the opening of the terminal shell in the Ubuntu 20.04 system via the “Ctrl+Alt+T” ...

Here is an example of using the break statement inside nested for loops . When the argument [n] is not given, break terminates the innermost enclosing loop. The outer loops are not terminated: for i in {1..3}; do for j in {1..3}; do if [[ $j -eq 2 ]]; then break fi ech...
