If statement and else statement could be nested in bash. The keyword “fi” indicates the end of the inner if statement and all if statement should end with the keyword “fi”. The “if then elif then else fi” example mentioned in above can be converted to the nested if as shown belo...
In theory, nested loops can go to infinite depth. In many situations, nested loops can be the perfect solution. Loop in bash script Bash is a powerful scripting language. There are different loop structures in the bash. The most popular ones are for, while, and until loops. If you’re ...
Due to the if condition, the loop will skip the echo command for value 3; therefore, the output will be: 1 2 4 5. Loop Over Command Line Arguments We can give command line arguments to our bash script and run a for loop over the arguments separated by spaces. See the example: for...
The first step in writing the script is to check if two arguments are provided. If not, we print a usage message and exit with a non-zeroexit code: $ cat convert_temp.sh #!/usr/bin/env bash # Check if two arguments are given if [ $# -ne 2 ]; then echo "Usage: $0 temperatur...
You would have to shutdown the PVE, modifying thekvmcommand and add the missing options. The major drawback is that this change would have to be made each time you boot if you need IOMMU support for passthrough. Fortunately, I've created aPython scriptto simplify the job. Hopefully, one...

Instead of using one of the pre-csh shells, e.g., sh, bsh, ksh, etc., would it be possible for you to code in csh or tcsh (*+_absolutely fuhgeddabout bash_+*)? If it is possible for you to code in csh or tcsh, then the whole switch/case syntax becomes much more natural...
$bashbash.sh Conclusion To sum up, this was all about the use of the nested “for” loop in the Bash script of the Ubuntu 20.04 Linux system. We have discussed the examples to see a simple “for” loop in Bash, nested “for” loop, and a one-line nested “for” loop in Bash sc...
