@Jim,

Thanks for your reply, and yes i am well aware about DATE command and its relevant formats, kindly follow my first post carefully as i mentioned that i cannot use any ls options because i am getting file listing from ftp server. Is there any command which can give me desired result directly from ftp while using ls?

TIA

Thank you @Ravinder,

I understood very well what you explained. Also can you tell me what if i have to extract year if i get input like this:

Code:
-rw-r--r-- 1 360 600 165923 Dec 31 11:29 12312019 file1_12312019_062449.csv

Here 2019 is not whole word rather part of second field, tried using substr but not able to get the idea that how to nest split and substr function.

TIA

CSREQ(1)						    BSD General Commands Manual 						  CSREQ(1)

NAME
csreq -- Expert tool for manipulating Code Signing Requirement data SYNOPSIS
csreq [-v] -r requirement-input -t csreq [-v] -r requirement-input -b outputfile DESCRIPTION
The csreq command manipulates Code Signing Requirement data. It reads one requirement from a file or command arguments, converts it into internal form, checks it, and then optionally outputs it in a different form. The options are as follows: -b path Requests that the requirement read be written in binary form to the path given. -r requirement-input Specifies the input requirement. See "specifying requirements" below. This is exactly the same format as is accepted by the -r and -R options of the codesign(1) command. -t Requests that the requirement read be written as text to standard output. -v Increases the verbosity of output. Multiple instances of -v produce increasing levels of commentary output. In the first synopsis form, csreq reads a Code Requirement and writes it to standard output as canonical source text. Note that with text input, this actually compiles the requirement into internal form and then converts it back to text, giving you the system's view of the requirement code. In the second synopsis form, csreq reads a Code Requirement and writes its binary representation to a file. This is the same form produced by the SecRequirementCopyData API, and is readily acceptable as input to Code Signing verification APIs. It can also be used as input to subse- quent invocations of csreq by passing the filename to the -r option. SPECIFYING REQUIREMENTS
The requirement argument (-r) can be given in various forms. A plain text argument is taken to be a path to a file containing the require- ment. This program will accept both binary files containing properly compiled requirements code, and source files that are automatically com- piled for use. An argument of "-" requests that the requirement(s) are read from standard input. Again, standard input can contain either binary form or text. Finally, an argument that begins with an equal sign "=" is taken as a literal requirements source text, and is compiled accordingly for use. EXAMPLES
To compile an explicit requirement program and write its binary form to file "output": csreq -r="identifier com.foo.test" -b output.csreq To display the requirement program embedded at offset 1234 of file "foo": tail -b 1234 foo | csreq -r- -t FILES
DIAGNOSTICS
The csreq program exits 0 on success or 1 on failure. Errors in arguments yield exit code 2. SEE ALSO
codesign(1) HISTORY
The csreq command first appeared in Mac OS 10.5.0 . BSD
June 1, 2006 BSD
