UNIX for Dummies Questions & Answers

Thank you vgersh99 for your response. I guess I did not explain what I want very well and it is probably because I am a dummy when if comes to this stuff. What I would like if possible is to turn that value - 1046099951 in to a date such as 20050420 . I don't know if it is possible, but thought I would ask. I have a file - users.txt that has a line for each user with their id and last time logged in. If possible I would like to have a script that will convert the value on each line. Thank you for your help so far.

not sure about AIX, but under Solaris one can convert epoch time to human-readable format like so:

Code:

   echo '0t1046099951=Y' | /usr/bin/adb

Others may have other ideas for AIX.

Ok I will try that. I might also try a perl script that will read each line in the file I created and then convert the value to a date. If anyone else has ideas please let me know. Thank you.

Here is a trick I picked up from Ygor:

Code:

#! /usr/bin/ksh

raw=1046099951
TIMESTAMP=$(perl -e '($ss, $mm, $hh, $DD, $MM, $YY) = localtime('$raw');
          printf "%04d%02d%02d%02d%02d", $YY + 1900 , $MM +1 , $DD, $hh, $mm')

echo $TIMESTAMP
exit 0

Thank you Perderabo I will incorporate that into a perl script. That was along the lines of what I was thinking of doing. I was rummaging around for a script when I checked back here. Thank you for everyones help. As usual this forum is very good at providing good examples. Of course it helps when I explain my problem better.
