For your first question, what do you mean by "check only a pattern of filename"? A substring?
Hello RudiC,
In the directory I will get filename say files-20170105-09.gz. I have to check if file exists also if exists then it should have today's date minus one. So I have to search this part 20170105. Rest of the part of file , I will not be knowing. That is the reason to check it I was using wildcard *

Hi,
I am writing a BASH script. I have a list of files and I would like to make sure that each is of a specific pattern (ie *.L2). If not I would like to remove that file. How do I test whether a filename matches a given pattern?
Thanks a lot.

is_readable
IS_READABLE(3) 1 IS_READABLE(3)is_readable - Tells whether a file exists and is readableSYNOPSIS
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.
