I have a shell script, and its pretty much done, I decided to add a loop that ends or continues depending on user input. like "would you like to continue?" and if I hit y or yes it will run the loop again until I hit n or no and breaks out of the loop.
To be hones I didn't think I needed to add the scipt it since it was just simple if statement with user input.

But... could anybody show me a script that, if the user option is incorrect, don't allow to continue the excution, i.e., if the value entered is not 1 or 2, the script shows a question.

Using ls input as example..
ls | sed 's/\n/ /'outputs with line breaks, where I was expecting the \n to disappear. I've tried \r as well wondering if terminal output used different breaks.
Is there a way to remove the line breaks without saving to file and then working from there?

Hi,
This query is a part of a much more lengthy script.
I wish to look for all the files in a folder named "data" which in this case has two files i.e. plan.war and agent.properties. For all the files found under data I wish to ask the user as to where they wish copy the files to.

break
break(1) User Commands break(1)NAME
break, continue - shell built-in functions to escape from or advance within a controlling while, for, foreach, or until loop
SYNOPSIS
sh
break [n]
continue [n]
csh
break
continue
ksh
*break [n]
*continue [n]
DESCRIPTION
sh
The break utility exits from the enclosing for or while loop, if any. If n is specified, break n levels.
The continue utility resumes the next iteration of the enclosing for or while loop. If n is specified, resume at the n-th enclosing loop.
csh
The break utility resumes execution after the end of the nearest enclosing foreach or while loop. The remaining commands on the current
line are executed. This allows multilevel breaks to be written as a list of break commands, all on one line.
The continue utility continues execution of the next iteration of the nearest enclosing while or foreach loop.
ksh
The break utility exits from the enclosed for, while, until, or select loop, if any. If n is specified, then break n levels. If n is
greater than the number of enclosing loops, the outermost enclosing loop shall be exited.
The continue utility resumes the next iteration of the enclosed for, while, until, or select loop. If n is specified then resume at the n-
th enclosed loop. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words that follow a command preceded by ** that are in the format of a variable assignment are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign, and also that word splitting and file name genera-
tion are not performed.
