If you don’t specify the keyword “in” followed by any list of values in the bash for loop, it will use the positional parameters (i.e the arguments that are passed to the shell script). $ cat for3.sh i=1 for day do echo "Weekday $((i++)) : $day" done $ ./for3.sh ...
the for loop will be executed a total of 5 times, once for each item in the list. The current item from the list will be stored in a variable “varname” each time through the loop. This “varname” can
For Loops Unlike most loops, theforloop does not test the condition of a variable each time it goes around the loop. Instead, it starts with a list of items to iterate through and works its way through them until it has reached the end. This makes it the most deterministic of the ...
Remember that you can combine the for loop with other Bash features, such as shell expansion, which allows Bash to expand a list of items that are in a series. This can work for letters and numbers. For example: $ echo {0..10} 0 1 2 3 4 5 6 7 8 9 10 Assuming your servers ...
If you want to check the processes using maximum swap memory in linux then you can use below bash for loop. In this example, we are using awk and sort tool with bash for loop to check the processes using swap memory as shown below....

to be aware of potential pitfalls when using ‘for’ loops as ‘foreach’ loops in Bash. For instance, if your list items contain spaces, the loop will treat each word as a separate item. To avoid this, you’ll need to use quotes or a different method to handle items with spaces. ...
Inside the loop, the user is prompted to enter their name. If the user inputs 'quit', the loop exits. Otherwise, it greets the user with their name. 5. Write a Bash script that utilizes a for loop to iterate through a list of files in the current directory and print each filename...
