I need something unusual, I guess. I need to start a process, and if that process displays a specific error message, I need to kill that process and restart it.
Something like:
Explanation, I need to start the process, check if it echoes any messages and if any of them is the one that I'm waiting, I need to kill that process.
Restarting of the process I can do putting all this in a while loop or something.
Is this possible at all? Is there any easier way to accomplish the same thing?

Hello,
How do I use grep to find a pattern in a list of file and then display 5 lines after the pattern is matched
Eg:
I want to match the string GetPresentCode in all files in a folder and then see 4 lines following this match. I am not sure if grep is what should be used to achieve. Thanks!... (3 Replies)

Good afternoon
I need to KILL a process in a single command sentence, for example:
kill -9 `ps -aef | grep 'CAL255.4ge' | grep -v grep | awk '{print $2}'`
That sentence Kills the process ID corresponding to the program CAL255.4ge.
However it is possible that the same program... (6 Replies)

kill
kill(2) System Calls Manual kill(2)NAME
kill - Sends a signal to a process or to a group of processes
SYNOPSIS
#include <signal.h>
int kill(
pid_t process,
int signal );
Application developers may want to specify an #include statement for <sys/types.h> before the one for <signal.h> if programs are being
developed for multiple platforms. The additional #include statement is not required on Tru64 UNIX systems or by ISO or X/Open standards,
but may be required on other vendors' systems that conform to these standards.
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
kill(): XSH5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies the process or group of processes. Specifies the signal. If the signal parameter is a value of 0 (the null signal), error check-
ing is performed but no signal is sent. This can be used to check the validity of the process parameter.
DESCRIPTION
The kill() function sends the signal specified by the signal parameter to the process or group of processes specified by the process param-
eter.
To send a signal to another process, at least one of the following must be true: The real or the saved set-user-ID of the sending process
matches the real or effective user ID of the receiving process. The process is trying to send the SIGCONT signal to one of its session's
processes. The calling process has root privileges.
Processes can send signals to themselves.
Sending a signal does not imply that the operation is successful. All signal operations must pass the access checks prescribed by each
enforced access control policy on the system.
If the process parameter is greater than 0 (zero), the signal specified by the signal parameter is sent to the process that has a process
ID equal to the value of the process parameter.
If the process parameter is equal to 0 (zero), the signal specified by the signal parameter is sent to all of the processes (other than
system processes) whose process group ID is equal to the process group ID of the sender.
If the process parameter is equal to -1, the signal specified by the signal parameter is sent to all of the processes other than system
processes for which the process has permission to send that signal. For example, if the effective user ID of the sender has root privi-
leges, the signal specified by the signal parameter is sent to all of the processes other than system processes.
If the process parameter is negative but not -1, the signal specified by the signal parameter is sent to all of the processes which have a
process group ID equal to the absolute value of the process parameter.
RETURN VALUES
Upon successful completion, the kill() function returns a value of 0 (zero). Otherwise, a value of -1 is returned and errno is set to indi-
cate the error.
NOTES
Some applications and scripts depend on the process ID of the init program being 1 (one): do not depend on it. Instead, use standard
methods, such as the ps and grep commands, to obtain all process IDs.
ERRORS
The kill() function sets errno to the specified values for the following conditions: The signal parameter is not a valid signal number.
[Tru64 UNIX] The signal parameter is SIGKILL, SIGSTOP, SIGTSTP or SIGCONT and the process parameter is the process ID of the init
program. No process or process group can be found corresponding to that specified by the process parameter. The real or saved user
ID does not match the real or effective user ID of the receiving process, the calling process does not have appropriate privilege,
and the process is not sending a SIGCONT signal to one of its session's processes. [Tru64 UNIX] The calling process does not have
appropriate privilege.
