Syntax points taken into account.
The first "else" clause is not needed.
Also, the script exits on the first file missing from "a/file.lst". To continue looking at the list, replace "exit" with "continue".

count2=`awk 'END {print NR}' $a/$filename`

then
echo "Same $count2 -$filename is present in Input Directory" >>a.log
else
echo "different $count2 -$filename is present in Input Directory" >>a.lo

LEARN ABOUT PHP
is_readable
IS_READABLE(3) 1 IS_READABLE(3)
is_readable - Tells whether a file exists and is readable
SYNOPSIS
bool is_readable (string $filename)
DESCRIPTION
Tells whether a file exists and is readable.
PARAMETERS
o $filename
- Path to the file.
RETURN VALUES
Returns TRUE if the file or directory specified by $filename exists and is readable, FALSE otherwise.
EXAMPLES
Example #1
is_readable(3) example
<?php
$filename = 'test.txt';
if (is_readable($filename)) {
echo 'The file is readable';
} else {
echo 'The file is not readable';
}
?>
ERRORS
/EXCEPTIONS
Upon failure, an E_WARNING is emitted.
NOTES
Keep in mind that PHP may be accessing the file as the user id that the web server runs as (often 'nobody'). Safe mode limitations are not
taken into account before PHP 5.1.5.
Note
The results of this function are cached. See clearstatcache(3) for more details.
Tip
As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to "Supported Protocols and Wrappers" to determine
which wrappers support stat(3) family of functionality.
Note
The check is done using the real UID/GID instead of the effective one.
This function may return TRUE for directories. Use is_dir(3) to distinguish file and directory.
SEE ALSO
is_writable(3), file_exists(3), fgets(3).
