This is a quick way to convert from epoch time to local time.
This can be used for example if running lsuser in AIX and converting the time_last_login field.
If lsuser gets back “time_last_login=1298298259“, then
perl -le 'print scalar localtime 1298298259' Mon Feb 21 14:24:19 2011 |
Viola – thankyou google and Nicholas.
You can also do the following in bash for example if you want to check the change time on a file…
file=/tmp/file
ctime=`stat $file | grep Change`
filetime=${ctime#Change\:*}
epochtime=`date -d "$filetime" +%s` # Convert from a datestamp to epoch secs
now=`date +%s` # Get current date/time in epoch secs
(( diffepoch = now - epochtime ))
if [[ $diffepoch -gt 60 ]];then
echo "$file is newer than 2 mins."
else
echo "$file is older than 2 mins."
