Hi
i want to print the time of a process in hours only..(or) in minutes only.Is there anyway to print the process such like that
when i give the commnand like following
#ps -eo pid,time
PID TIME
412 01:49:32
481 00:03
it shows in HH:MM:SS format:
Could anyone... (1 Reply)
i have the time 20100421043335 in format (date +%Y%m%d%H%M%S),and i want to be able to get the previous time 2 minutes ago,which is

I have several logs with where the time stamp in the logs are "YYYYMMDDHHMM".
I would like to check the last line in each file to make sure the entry is less than 5 minutes old.
My timezone is EST5EDT so the following will work for 1 hour. But I need something easy for 5 minutes ago.... (5 Replies)
In Redhat it is easy....
date --date="60 minutes ago"
How do you do this in Solaris?
I got creative and got the epoch time but had problems..
EPOCHTIME=`truss date 2>&1 | grep "time()" | awk '{print $3 - 900}'`
echo $EPOCHTIME
TIME=`perl -e 'print scalar(localtime("$EPOCHTIME")),... (5 Replies)
Hello All
I know the general Logic behind it but do not know the shell programming so much.
For Example, The Time is stored in a given Variable
if the Time is 0800 then i need to extract the last digits of the number and Add it to the Remaining Digit of the Number which is multiplied by... (7 Replies)
Hi Folks,
I have a text file that has only time in the format HH:MM:SS like seen below.
21:36:17
23:52:08
I need to find the difference in minutes alone from this text file so the result would be 136.
Thanks

Hello,
date --date '-60 min ago' +'%Y-%m-%d %H:%M:%S,%3N'
Above command gives the date and time minus 60 minutes
but the problem i am facing is, i do not want to hardcode the value 60
it is stored in a variable var=60
now if i run below command , i get error
date --date '-$var min... (3 Replies)
Hello all,
Info:
System RedHat 7.5
I need to create a script that based on the creation time,
if the file is older then 5 minutes then execute some stuff, if not exit.
I thought to get the creation time and minutes like this.

devel::refcount
Devel::Refcount(3pm) User Contributed Perl Documentation Devel::Refcount(3pm)NAME
"Devel::Refcount" - obtain the REFCNT value of a referent
SYNOPSIS
use Devel::Refcount qw( refcount );
my $anon = [];
print "Anon ARRAY $anon has " . refcount($anon) . " reference
";
my $otherref = $anon;
print "Anon ARRAY $anon now has " . refcount($anon) . " references
";
DESCRIPTION
This module provides a single function which obtains the reference count of the object being pointed to by the passed reference value.
FUNCTIONS
$count = refcount($ref)
Returns the reference count of the object being pointed to by $ref.
COMPARISON WITH SvREFCNT
This function differs from "Devel::Peek::SvREFCNT" in that SvREFCNT() gives the reference count of the SV object itself that it is passed,
whereas refcount() gives the count of the object being pointed to. This allows it to give the count of any referent (i.e. ARRAY, HASH,
CODE, GLOB and Regexp types) as well.
Consider the following example program:
use Devel::Peek qw( SvREFCNT );
use Devel::Refcount qw( refcount );
sub printcount
{
my $name = shift;
printf "%30s has SvREFCNT=%d, refcount=%d
",
$name, SvREFCNT($_[0]), refcount($_[0]);
}
my $var = [];
printcount 'Initially, $var', $var;
my $othervar = $var;
printcount 'Before CODE ref, $var', $var;
printcount '$othervar', $othervar;
my $code = sub { undef $var };
printcount 'After CODE ref, $var', $var;
printcount '$othervar', $othervar;
This produces the output
Initially, $var has SvREFCNT=1, refcount=1
Before CODE ref, $var has SvREFCNT=1, refcount=2
$othervar has SvREFCNT=1, refcount=2
After CODE ref, $var has SvREFCNT=2, refcount=2
$othervar has SvREFCNT=1, refcount=2
Here, we see that SvREFCNT() counts the number of references to the SV object passed in as the scalar value - the $var or $othervar
respectively, whereas refcount() counts the number of reference values that point to the referent object - the anonymous ARRAY in this
case.
Before the CODE reference is constructed, both $var and $othervar have SvREFCNT() of 1, as they exist only in the current lexical pad. The
anonymous ARRAY has a refcount() of 2, because both $var and $othervar store a reference to it.
After the CODE reference is constructed, the $var variable now has an SvREFCNT() of 2, because it also appears in the lexical pad for the
new anonymous CODE block.
PURE-PERL FALLBACK
An XS implementation of this function is provided, and is used by default. If the XS library cannot be loaded, a fallback implementation in
pure perl using the "B" module is used instead. This will behave identically, but is much slower.
