Hey people
I am currently working on a print spooler for unix over a network. I need help regarding the status of the printer. Is there any way to know when the printer has finished a previous job, so that the next job from the queue can be processed. Also is there any other way to print other... (0 Replies)

Hi,
On my Linux machine, using Bash, I sometimes run into a situation where doing the following does not seem to work at all.

I have a script that conducts some SSH calls and I would like to capture the child info so that I can do a sleep and then a cleanup to make sure they do not stay out there as ghosts.
I was told I could do something like this...
#!/bin/sh
for m = job1, job2, job3

Hi,
I wrote a script to kill a process id.
I am able to kill the PID only if I enter the root password in the middle of the execution because I did not run as root i.e after i run the script from the terminal, instead of killing directly, it is killing only after entering the pass when it... (12 Replies)
Hi there !!!
I am writing a script to kill the pids on different linux boxes :cool:
the output of my command gives the pids running on that box, but how can I kill all the pids without looping? :confused:
Code:

Hello Friends,
I've been trying to write a one line which checks java processes and filter them for a user (testuser) and then check process arguments with PARGS command and then check if there is certain patterns exists in pargs output then kill the process.

I created a program to kill long running pid processes.
I am getting the following error message:
-f command cannot be found.
I also want to count the number of pids that are killed and append the results to a text file. I am new to shell script programming.

itimerspec
TIMEVAL(3) BSD Library Functions Manual TIMEVAL(3)NAME
timeval, timespec, itimerval, itimerspec, bintime -- time structures
SYNOPSIS
#include <sys/time.h>
void
TIMEVAL_TO_TIMESPEC(struct timeval *tv, struct timespec *ts);
void
TIMESPEC_TO_TIMEVAL(struct timeval *tv, struct timespec *ts);
DESCRIPTION
The <sys/time.h> header, included by <time.h>, defines various structures related to time and timers.
1. The following structure is used by gettimeofday(2), among others:
struct timeval {
time_t tv_sec;
suseconds_t tv_usec;
};
The tv_sec member represents the elapsed time, in whole seconds. The tv_usec member captures rest of the elapsed time, represented as
the number of microseconds.
2. The following structure is used by nanosleep(2), among others:
struct timespec {
time_t tv_sec;
long tv_nsec;
};
The tv_sec member is again the elapsed time in whole seconds. The tv_nsec member represents the rest of the elapsed time in nanosec-
onds.
A microsecond is equal to one millionth of a second, 1000 nanoseconds, or 1/1000 milliseconds. To ease the conversions, the macros
TIMEVAL_TO_TIMESPEC() and TIMESPEC_TO_TIMEVAL() can be used to convert between struct timeval and struct timespec.
3. The following structure is used by setitimer(2), among others:
struct itimerval {
struct timeval it_interval;
struct timeval it_value;
};
4. The following structure is used by timer_settime(2), among others:
struct itimerspec {
struct timespec it_interval;
struct timespec it_value;
};
Both struct itimerval and struct itimerspec are used to specify when a timer expires. Generally, it_interval specifies the period
between successive timer expirations. A value zero implies that the alarm will fire only once. If it_value is non-zero, it indicates
the time left to the next timer expiration. A value zero implies that the timer is disabled.
5. The following structure is used by bintime(9), among others:
struct bintime {
time_t sec;
uint64_t frac;
};
The sec member specifies the time in seconds and frac represents a 64-bit fraction of seconds. The struct bintime is meant to be used
in the kernel only. It is further described in timecounter(9).
EXAMPLES
It can be stressed that the traditional UNIX timeval and timespec structures represent elapsed time, measured by the system clock (see
hz(9)). The following sketch implements a function suitable for use in a context where the timespec structure is required for a conditional
timeout:
static void
example(struct timespec *spec, time_t minutes)
{
struct timeval elapsed;
(void)gettimeofday(&elapsed, NULL);
_DIAGASSERT(spec != NULL);
TIMEVAL_TO_TIMESPEC(&elapsed, spec);
/* Add the offset for timeout in minutes. */
spec->tv_sec = spec->tv_sec + minutes * 60;
}
A better alternative would use the more precise clock_gettime(2).
