This will make it ambiguous when more than one identical name with different cases exists.Whichever comes first in the arbitrary listing order wins. I was told that in most paths, only the two last directories would be in random case (that is: /Bla/Bla/Bla/random case/random case).

If the conversion was successful, the method returns the result in the correct type.

If the conversion failed, the code outputs and error message and requests the user to re-enter a proper input.

Then I might be supplied those same folder names as parameters in different combos..

and even if not, even if I always get the parameters in the same case, I still need to find out in what case exactly that folder is written in, because I need to transfer files there.

First, we set up a method to test whether or not the accepted input can be converted to a specific type: The loop is called with a string parameter that decides which message the user will see.

This message will repeat itself each time the loop requests for the input.In this case, we expect the input to be an integer.The keyboard Scanner accepts any string so it would not break on error, but then tries to convert it to the proper type using “is Type” method.expects an integer, next Double expects a double, next Float expects a float and next Line expects a string.With the exception of strings, if a user inputs the wrong type, the code will produce an exception and (if not handled correctly) will stop.Trying to create a script in BASH that would ask the user to enter another user name making sure the input is not blank before they hit enter then to check the home directory of that user does exist, I have the check folder sorted it's just the loop to make sure the user has entered chars#!/bin/bash cd /home/ echo -n "Enter Users Name : " read name while read a; do if [[ -z "$" ; then echo "That was empty, do it again!I would use the grep() function instead open each dir and read all its contents.Regards, Birei The paths end with /enviornment/application_code.Hi, I need to copy files from a source directory to a destination directory in unix. The problem is that the source and dest directories are supplied by different users, who might type the name of the directories in various combinations of lower case and upper case.This would be easy to solve, except no one kept here a naming standard, so the actual directories in unix can also be different combinations of uc and lc.
