The Bash for loop To achieve a recursive loop through directories, we will use bash loops, specifically, a for a loop. The for loop is a common type of loop in Bash and other programming languages. It iterates over a given list of items/options until and executes a set of commands. T...
Write a Bash script that uses a for loop to iterate over a list of names and prints a greeting message for each name. Code: #!/bin/bash# Define a list of namesnames=("Iolanda""Valeri""Sheela""Jana""Hartwig")# Iterate over the list of names using a for loopfornamein"${names[@]}...
sh test.sh path/to/loop/over Nevertheless, the aforementioned code does not generate the files in the directory labeled aspath/to/loop/over. Instead, it generates a different output. File: path/to/loop/over/* It seems that the program is treatingpath/to/loop/over/*as a string instead of...

Example 1: Loop through a Given Range #!/bin/bash # Print numbers from 1 to 5 for i in $(seq 1 5); do echo $i done In the above snippet, the $(seq 1 5) part is used to generate a list of integers from 1 to 5. It will then loop over the list one by one and then ea...
