while [ -z "$dest_dir" ]
do
read dest_dir?"Please Enter Directory :"
if [ -d $dest_dir ];
then
echo "Invalid directory entered. Please try again"
fi
done
When executed and if the response is just a "CR". I get the following
test.sh
Please Enter Directory :
test.sh[4]: test: 0403-004 Specify a parameter with this command.
Please Enter Directory :
To overcome the same I changed line 4 to also include quotes. Also I included the negation on this check to make it work correctly as follows
Code:
while [ ! -d "$dest_dir" ]
do
read dest_dir?"Please Enter Directory :"
if [ ! -d "$dest_dir" ];
then
echo "Invalid directory entered. Please try again"
fi
done
.
Thanks.

LEARN ABOUT PHP
dir
DIR(3) 1 DIR(3)dir - Return an instance of the Directory classSYNOPSIS
Directory dir (string $directory, [resource $context])
DESCRIPTION
A pseudo-object oriented mechanism for reading a directory. The given $directory is opened.
PARAMETERS
o $directory
- Directory to open
o $context
-
Note
Context support was added with PHP 5.0.0. For a description of contexts, refer to "Streams".
RETURN VALUES
Returns an instance of Directory, or NULL with wrong parameters, or FALSE in case of another error.
EXAMPLES
Example #1
dir(3) example
Please note the fashion in which Directory.read(3)'s return value is checked in the example below. We are explicitly testing
whether the return value is identical to (equal to and of the same type as - see Comparison Operators for more information) FALSE
since otherwise, any directory entry whose name evaluates to FALSE will stop the loop.
<?php
$d = dir("/etc/php5");
echo "Handle: " . $d->handle . "
";
echo "Path: " . $d->path . "
";
while (false !== ($entry = $d->read())) {
echo $entry."
";
}
$d->close();
?>
The above example will output something similar to:
Handle: Resource id #2
Path: /etc/php5
apache
cgi
cli
NOTES
Note
The order in which directory entries are returned by the read method is system-dependent.
