Top Forums Shell Programming and Scripting Rsh reboot in a loop? Post 303026133 by MuntyScrunt on Tuesday 20th of November 2018 03:28:46 PM

Ok, well incorporating those couple of things (I'm still using cat. I like cat. I have one!) does make a difference, it now loops for two nodes, it resets at least one of them, them closes my ssh to the header machine.

Just before my session is closed the error tcserror: Input/output error is thrown.

I have since tried nohup and disown, these do similar, they run for a couple of loops then just end.

I should add at this point I've checked and checked, there is no problem with my nodes file. So I continue to be confused.

The problem surely is I want to explicitly ignore "Connection lost', not an error. Connection lost isn't an error, is a loss of connection, it's not a return from the command.

So, now I'm very confused.

EDIT: pssh manages fine which is a python script, so it must be possible with bash surely?

NAME

       reboot - reboot system or halt processor

SYNOPSIS

       #include <sys/reboot.h>

       int reboot(int howto, char *bootargs);

       The  reboot()  function	reboots  the  system.	The howto argument specifies the behavior of the system while rebooting and is a mask con-
       structed by a bitwise-inclusive-OR of flags from the following list:

       RB_AUTOBOOT     The machine is rebooted from the root filesystem on the default boot device. This is the default behavior. See boot(1M) and
		       kernel(1M).

       RB_HALT	       The processor is simply halted; no reboot takes place. This option should be used with caution.

       RB_ASKNAME      Interpreted by the bootstrap program and kernel, causing the user to be asked for pathnames during the bootstrap.

       RB_DUMP	       The  system  is	forced	to panic immediately without any further processing and a crash dump is written to the dump device
		       (see dumpadm(1M)) before rebooting.

       Any other howto argument causes the kernel file to boot.

       The interpretation of the bootargs argument is platform-dependent.

       Upon successful completion, reboot() never returns.  Otherwise, -1 is returned and errno is set to indicate the error.

       The reboot() function will fail if:

       EPERM	The {PRIV_SYS_CONFIG} privilege is not asserted in the effective set of the calling process.

       intro(1M), boot(1M), dumpadm(1M), halt(1M), init(1M), kernel(1M), reboot(1M), uadmin(2)
