Time command issuing all zeroes
I am trying to issue the time command on a program so I can see execution times but it is returning all zeroes. Like this:
time pdriver arg1 arg2
0.000u 0.000s 0:00.00 0.0% 0+0k 0+0io 0pf+0w
"0+0k 0+0io 0pf+0w" --> The "0+0io" may change sometimes to a different number.
How can I run the time command successfully? I'm using a unix terminal and my program is in c++.

I have a filename 'INITIATE_FINAL_ALL_000080889.dat', and I want to capture just the number '80889' from it.
Here is what I have so far:
%> echo INITIATE_FINAL_ALL_000080889.dat | sed "s/*//g"
000080889
Now, I just need to trim off the padded zeroes.
Thanks,

I wondered if someone could point out the differences between the time commmand and usr/bin/time and the accuracy one might have over another.
Also, is there a website or two a person could maybe link for me to describe the differences?

Hi,
Using ksh, I have set up aliases (which work fine) in my user's .profile like this:
alias ll = 'ls -lrt'
alias cls = 'clear'
How do I call these same aliases so that they will work after issuing this: ? su - user
I do not want to add aliases to the su shell's .profile or .kshrc. (7 Replies)

Simple(3pm) User Contributed Perl Documentation Simple(3pm)
NAME
Thread::Pool::Simple - A simple thread-pool implementation
SYNOPSIS
use Thread::Pool::Simple;
my $pool = Thread::Pool::Simple->new(
min => 3, # at least 3 workers
max => 5, # at most 5 workers
load => 10, # increase worker if on average every worker has 10 jobs waiting
init => [&init_handle, $arg1, $arg2, ...] # run before creating worker thread
pre => [&pre_handle, $arg1, $arg2, ...] # run after creating worker thread
do => [&do_handle, $arg1, $arg2, ...] # job handler for each worker
post => [&post_handle, $arg1, $arg2, ...] # run before worker threads end
passid => 1, # whether to pass the job id as the first argument to the &do_handle
lifespan => 10000, # total jobs handled by each worker
);
my ($id1) = $pool->add(@arg1); # call in list context
my $id2 = $pool->add(@arg2); # call in scalar conetxt
$pool->add(@arg3) # call in void context
my @ret = $pool->remove($id1); # get result (block)
my $ret = $pool->remove_nb($id2); # get result (no block)
$pool->cancel($id1); # cancel the job
$pool->cancel_all(); # cancel all jobs
$pool->join(); # wait till all jobs are done
$pool->detach(); # don't wait.
DESCRIPTION
"Thread::Pool::Simple" provides a simple thread-pool implementaion without external dependencies outside core modules.
Jobs can be submitted to and handled by multi-threaded `workers' managed by the pool.
