In this example, we have two arrays:fruitsandcolors. We use a ‘for’ loop to iterate through the indices of thefruitsarray (obtained using the!symbol before the array variable). For each iteration, we print out
#!/bin/bash # Iterate through the list of files in the current directory for file in *; do # Check if the file is a regular file (not a directory) if [[ -f "$file" ]]; then echo "$file" fi done CopyOutput:abc.sh document.txt error.log file1.txt file2.txt input.txt ...

# Iterate the string array using for loop for val in ${StringArray[@]}; do echo $val done Output: $ bash for_list3.sh Example-4: Print multiple words string value as a single value Create a bash file named ‘for_list4.sh’ and add the following script. In this example, every el...
How to iterate over a Bash Array? (loop) As discussed above, you can access all the values of a Bash array using the * (asterisk) notation. Though, to iterate through all the array values you should use the @ (at) notation instead. ...
In case your server names are not easy to iterate through, you can provide a list of names to theforloop: $catsomelist first_item middle_things foo bar baz last_item $foriin`catsomelist`;doecho"ITEM:$i";doneITEM: first_item

How to find if a number is odd or even in bash? How to iterate over a bash array? How to loop over each line of a file? How to iterate over a list of files? How to use numbers with leading zeros in a bash loop? How to iterate over a range of numbers defined by variables?
In this script, the ‘for’ loop iterates over the numbers 1 through 10. For each iteration, the ‘if-elif-else’ statement checks if the current number is equal to 5 or 7 and prints a message accordingly. ‘Else If’ with Functions ...
Now comes the fun part; we need to set up the for loop, which using the iterator “i” will iterate through the array’s contents and perform the display function. You can do it as such: This line sets up the loop. With the “$” symbol, we are specifying that we are trying to...
