filename represents each element in the list returned by $(ls). I will say now that for is not the right way to do this task.
Each word output by ls is assigned into filename variable. That is the name you gave on the for line. The reason for is bad is because a filename with a space will actually be treated as two words because of "word splitting", but let's continue anyway...
filename can be any variable name. $(ls) can be replaced by any list. for example:
This is a proper list. If you want a properly split list of files, use a glob:
We can leave out the parameter expansion to get the extension and just do that logic in the case patterns.
#!/bin/bash
for file in $HOME/*;
do
if ; then
rm -i $file > /dev/null
echo "$?"
echo "$file has been deleted"
fi
done

LEARN ABOUT PHP
php_strip_whitespace
PHP_STRIP_WHITESPACE(3) 1 PHP_STRIP_WHITESPACE(3)php_strip_whitespace - Return source with stripped comments and whitespaceSYNOPSIS
string php_strip_whitespace (string $filename)
DESCRIPTION
Returns the PHP source code in $filename with PHP comments and whitespace removed. This may be useful for determining the amount of actual
code in your scripts compared with the amount of comments. This is similar to using php -w from the commandline.
PARAMETERS
o $filename
- Path to the PHP file.
RETURN VALUES
The stripped source code will be returned on success, or an empty string on failure.
Note
This function works as described as of PHP 5.0.1. Before this it would only return an empty string. For more information on this
bug and its prior behavior, see bug report #29606.
EXAMPLES
Example #1
php_strip_whitespace(3) example
<?php
// PHP comment here
/*
* Another PHP comment
*/
echo php_strip_whitespace(__FILE__);
// Newlines are considered whitespace, and are removed too:
do_nothing();
?>
The above example will output:
<?php
echo php_strip_whitespace(__FILE__); do_nothing(); ?>
Notice the PHP comments are gone, as are the whitespace and newline after the first echo statement.
