}

usage :
Code:
$ dmesg | perl time.pl

That didn't work ;(



Code:
# dmesg | perl time.pl | more
syntax error at time.pl line 1, near "$ cat time"
"use" not allowed in expression at time.pl line 3, at end of line
Execution of time.pl aborted due to compilation errors.



I tried this one:

Code:
#!/usr/bin/perl -wn
use strict;
foreach my $line (<>) {
    my ($uptime) = do { local @ARGV='/proc/uptime';<>}; ($uptime) = ($uptime =~ /^(\d+)\./);
    $line=~/^\[\s*(\d+)\.\d+\](.+)/;
    printf "[%s]%s\n", scalar localtime(time - $uptime + $1), $2;
}

But it's also not working ;(

Code:
Can't open /proc/uptime: No such file or directory at time.pl line 5.
Use of uninitialized value in pattern match (m//) at time.pl line 5.
Use of uninitialized value in subtraction (-) at time.pl line 7.
Use of uninitialized value in addition (+) at time.pl line 7.
Use of uninitialized value in printf at time.pl line 7.




Code:
dmesg | more

... doesn't show date - just on the top I could see the actual date ;-(

LEARN ABOUT POSIX

uptime

UPTIME(1)							   User Commands							 UPTIME(1)

NAME

       uptime - Tell how long the system has been running.

SYNOPSIS

       uptime [options]

DESCRIPTION

       uptime  gives  a one line display of the following information.	The current time, how long the system has been running, how many users are
       currently logged on, and the system load averages for the past 1, 5, and 15 minutes.

       This is the same information contained in the header line displayed by w(1).

       System load averages is the average number of processes that are either in a runnable or uninterruptable state.	A process  in  a  runnable
       state is either using the CPU or waiting to use the CPU.  A process in uninterruptable state is waiting for some I/O access, eg waiting for
       disk.  The averages are taken over the three time intervals.  Load averages are not normalized for the number of CPUs in  a  system,  so  a
       load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.

OPTIONS

       -p, --pretty
	      show uptime in pretty format

       -h, --help
	      display this help text

       -s, --since
	      system up since, in yyyy-mm-dd HH:MM:SS format

       -V, --version
	      display version information and exit

FILES

       /var/run/utmp
	      information about who is currently logged on

       /proc  process information

AUTHORS

       uptime was written by Larry Greenfield <greenfie@gauss.rutgers.edu> and Michael K. Johnson <johnsonm@sunsite.unc.edu>
