String in double quote: echo -e "This is First Line \nThis is Second Line" String in single quote: echo -e 'This is First Line \nThis is Second Line' I do this because the shells parser expands glob patterns after it performs field splitting on variables.

Create a bash file named ‘for_list2.sh’ and add the following script.Assign a text into the variable, StringVal and read the value of this variable using for loop.This example will also work like the previous example and divide the value of the variable into words based on the space. Use one of followings examples. #!/bin/bash echo 'Eine Zeile mit Umbruch'; echo -n 'Eine Zeile ohne Umbruch, '; echo 'direkt gefolgt von einer weiteren Zeile. This output is without a terminating newline because the format string was "%c" and it doesn't include \n. NR is total record processed so far, and FNR is total record processed in current file.
