To exit a nested loop and an outer loop, usebreak 2. Continue Thecontinuecommand ends the current loop iteration. The program continues the loop, starting with the following iteration. To illustrate, add the following code to a Bash script to see how thecontinuestatement works in aforloop: ...
Bash is an acronym for ‘Bourne-Again SHell’. The Bourne shell is the traditional Unix shell originally written by Stephen Bourne. All of the Bourne shell builtin commands are available in Bash, The rules for evaluation and quoting are taken from thePOSIXspecification for the ‘standard’ Unix...

When parsing arguments in Bash, using the index operator allows for starting the indexing from the shifted position. Other solutions on the same page cannot perform this function. Moreover, this operator handles spaces, quoting characters, and binary in arguments, which non-enhanced solutions cannot...
loop has the nameref attribute, the list of words can be a list of shell variables, and a name reference will be established for each word in the list, in turn, when the loop is executed. Array variables cannot be given the -n attribute. However, nameref variables ...
This is useful for tasks like displaying data, modifying values, or performing computations. For example, here I wrote a simple for loop to print the keys and elements accordingly: for key in "${!myarray[@]}"; do echo "Key: $key, Value: ${myarray[$key]}" ...
The for loop prints a Bash associative array (both the keys and values) successfully. Here’s an example: #!/bin/bash #declare an associative array declare -A my_assoc_array #populate the array with values my_assoc_array["fruit"]="apple" my_assoc_array["vegetable"]="carrot" my_assoc...
In this paper, we present an approach that allows preprocessing large tabular data in Datalog – without indexing the data. The Datalog query is trans- lated to Unix Bash and can be executed in a shell. Our experiments show that, for the use case of data preprocessing, our approach is ...
The shift operator in Bash (syntacticallyshift n, wherenis the number of positions to move) shifts the position of the command-line arguments. The default value fornis one if not specified. The shift operator causes the indexing of the input to start from the shifted position. In other words...
