I’m looking for a command on AIX 7.1 that can give me filenames, size, and complete date/time (in a uniform format).

  • ls -l and similar commands have the drawback that they give date (month and day) and time (hour and minute), if the file is not older than 6 months, and date and year otherwise.  (I want year, month, day, hour, minutes and seconds for all files.)

  • The AIX version of ls does not support --full-time, reporting

    ls: Not a recognized flag: -
ls: Not a recognized flag: -
Usage: ls [-1ACFHLNRSabcdefgiklmnopqrstuxEUX] [File...]

What command that exists on AIX will give me the full date/time, in a consistent format, and the file size?

Indeed, istat appears to solve your problem; from the man page:

$ istat /usr/bin/ksh

Inode 10360 on device 10/6    File
Protection: r-xr-xr-x
Owner: 2(bin)     Group: 2(bin)
Link count: 2     Length 372298 bytes

... gives the file size and full timestamps.

Both istat and perl may be of help:

#!/usr/bin/env bash

echo
rm -f f1
touch f1

echo
echo " With perl:"
perl -e '@d=localtime ((stat(shift))[9]); printf "%02d-%02d-%04d %02d:%02d:%02d\n", $d[3],$d[4]+1,$d[5]+1900,$d[2],$d[1],$d[0]' f1

echo
echo " With istat:"
istat f1

producing:

$ ./s1


 With perl:
14-10-2017 14:26:01

 With istat:
Inode 1371634 on device 45/3    File
Protection: rw-r--r--   
Owner: 1296(drl)                Group: 100(usr)
Link count:   1         Length 0 bytes

On a system like:

aix 7.1.0.0
istat - ( /usr/bin/istat, Aug 08 2010 )
perl 5.10.1

Best wishes ... cheers, drl
