Answer / hema
Using sh -x script argument you can debug(-x option).
Bash shell offers debugging options which can be turn on or
off using
set command.
=> set -x : Display commands and their arguments as they are
executed.
=> set -v : Display shell input lines as they are read.
Hope this answers your question.
