ls command to return the date time stamp along with year for the files along the directory.Tried all possible options of ls command,it is either returning the date or date time without year or date with year but not date time(hh:mm) year.Kindly provide any inputs for ls command for above case on AIX server.

find /dir/abc -name '*.txt' -mtime +180 -exec ls -lu ; 

this command gives me output like below without the year: Output:

-rw-r--r-- 1 cdwgrp cdwgrp 16384 Oct 15 07:28 /dir/abc/compass.txt

And the other command:

find /dir/abc -name '*.txt' -mtime +180 -exec ls -e ;

to return the year. This gives me an output like below without the timestamp:

-rw-r--r-- 1 cdwgrp cdwgrp 16384 Oct 15 2016 /dir/abc/compass.txt

I want my output to have both the timestamp and year which should be executable on AIX

Here's a hack that should work according to the aix tar man page. Use tar tv to list the timestamp.

$ tar cf - filea fileb | tar tvf -
-rw-r--r-- 114 1993-11-24 02:22 filea
-rw-r--r-- 6459 2016-04-19 21:43 fileb

I dont have an aix to test it on.

Running this:

#!/usr/bin/env bash

echo
rm -f f1 t2
touch f1
# [[[CC]YY]MMDDhhmm[.SS]]
touch -t "201111041422.16" f2 

echo
echo " With ls:"
ls -l f?

echo
echo " With istat:"
istat f2

echo
echo " With tar:"
tar cf - f1 f2 | tar tvf -

produces this:

./s2


 With ls:
-rw-r--r-- 1 drl usr 0 Oct 15 19:28 f1
-rw-r--r-- 1 drl usr 0 Nov 04 2011 f2

 With istat:
Inode 1371635 on device 45/3 File
Protection: rw-r--r-- 
Owner: 1296(drl) Group: 100(usr)
Link count: 1 Length 0 bytes

 With tar:
-rw-r--r-- 1296 100 0 Oct 15 19:28:03 2017 f1
-rw-r--r-- 1296 100 0 Nov 04 14:22:16 2011 f2

On a system like:

aix 7.1.0.0
bash GNU bash 4.2.10
ls - ( /usr/bin/ls, Sep 05 2012 )
istat - ( /usr/bin/istat, Aug 08 2010 )
tar - ( /usr/bin/tar, Nov 27 2012 )

Best wishes ... cheers, drl

On Linux, read ls(1) man page (or run man ls). Perhaps you want its --full-time option (of the GNU coreutils ls). For example on my Debian/Sid computer I can get:

% ls --full-time bismon.h
-rw-r--r-- 1 basileus basilegr 646 2017-08-25 06:35:27.960509752 +0200 bismon.h

On AIX, read also the documentation (probably also the man page) of ls.

BTW, the Linux ls command is often from the GNU coreutils which you could compile and install on AIX. Then you'll get the same ls on both Linux and AIX. With some precautions, you don't even need root access to do that, and I recommend you to do that.

Consider also using date(1) using its -r option, e.g.

find /dir/abc -name '*.txt' -mtime +180 
 -exec echo -n ; -exec date -r '+ %Y-%m-%d %H:%M:%S' ; 

Or, hoping that AIX is nearly POSIX compliant, restrict yourself to the options of POSIX ls.

BTW, read also locale(7). You might setup some environment variables appropriately.

Otherwise, compile some small C program on AIX (or write in some scripting language like Python, Perl, GNU awk, ...), which uses the readdir(3) and related functions with stat(2) system call and time related functions (localtime(3), strftime(3), etc...). You could even avoid the find by using nftw(3).

PS. The simplest way is to compile and install GNU coreutils on AIX (or ask the sysadmin to do that), and you don't need root priviledges if you take some precautions.
