Full Discussion: Command line buffer limit?
Top Forums UNIX for Dummies Questions & Answers Command line buffer limit? Post 33487 by RTM on Tuesday 7th of January 2003 09:37:54 AM

Thanks Perderabo. I did two different commands (one to create a directory which I realized may have been a problem other than the 'limit' on command line) but both errored by beeping constantly and giving an error in the middle of the line.

On one, it cut a grep command and came back with "command not found" for "rep" and the other died along the same line (same number of characters).

cat passwd | grep h | grep o | grep m | grep e | grep a | grep i | grep o | grep 8 | grep 1 | grep 3 | grep 2 | grep 9 | grep "-" | grep S | grep b | grep l | grep t | grep L | grep 4 | grep d | grep r | grep 0 | grep V | grep I | grep abal | grep k | grep and | grep ers | grep eit | grep N | grep z | grep w | grep g | grep N
$ V | grep I | grep abal | grep k | grep <
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] -e pattern_list...
[-f pattern_file...] [file...]
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] [-e pattern_list...]
-f pattern_file... [file...]
usage: grep [-E|-F] [-c|-l|-q] [-bhinsvx] pattern [file...]

Note that when hitting return, it errors and gives back a prompt and includes the rest of the line as a start of a new command ($ V | grep 1 ....).

This is probably some other parameter set differently from one system to the next (or possibly shell) but I figured I would ask about it. I can also get the same response on Solaris even though I found some indication that the same information you suggested was true for it too. Ksh on HP and csh on Solaris. And for some reason I get a few more characters (about 40 ) on Solaris. The whole thing is strange and inconsistant.

instances.conf

INSTANCES.CONF(5)						  [FIXME: manual]						 INSTANCES.CONF(5)

NAME

       instances.conf_ - zorp(8) instances database

DESCRIPTION

       The instances.conf file describes the zorp(8) instances to be run on the system. It is processed by zorpctl(8) line by line, each line
       having the structure described below. Empty lines and lines beginning with '#' are comments ignored by zorpctl.

STRUCTURE

       instance-name parameters [-- zorpctl-options]

       instance-name is the name of the Zorp instance to be started; it is passed to zorp with its --as parameter. Instance names may consist of
       the characters [a-zA-Z0-9_] and must begin with a letter.

       parameters are space separated parameters entered into the zorp command-line. For details on these command-line parameters see zorp(8).

       zorpctl-options are space separated parameters control startup specific options. They are processed by zorpctl itself. The following
       zorpctl options are available:

       --auto-restart or -A
	   Enable the automatic restart feature of zorpctl. When an instance is in auto-restart mode, it is restarted automatically in case the
	   instance exits.

       --no-auto-restart or -a
	   Disable automatic restart for this instance.

       --fd-limit <number> or -f <number>
	   Set the file descriptor limit to <number>. The file descriptor limit defaults to the number of threads (specified by the --threads
	   parameter of zorp(8)) multiplied by 4.

       --process-limit <number> or -p <number>
	   Set the process limit to <number>. The process limit defaults to the number of threads (specified by the --threads parameter of
	   zorp(8)) multiplied by 2.

       --enable-core
	   Explicitly enable core dumps for Zorp processes. The core limit is inherited from the local starting environment (e.g.: starting shell)
	   if not specified.

       --parallel-instances <number> or -P <number>
	   Run <number> of processes for the instance.	zorpctl starts exactly one Zorp process in master mode and <number> of slave Zorp
	   processes. This mode of operation is incompatible with old-style dispatchers, you must use the new rule-based policy with this option.

EXAMPLES

       zorp_ftp --policy /etc/zorp/policy.py --verbose 5

       The line above describes a Zorp instance named zorp_ftp using policy file /etc/zorp/policy.py, and having verbosity level 5.

       zorp_intra -v4 -p /etc/zorp/policy.py --threads 500 --no-auto-restart --fd-limit 1024 --process-limit 512

       This line describes a zorp instance named zorp_intra using the policy file /etc/zorp/policy.py, verbosity level 4. The maximum number of
       threads is set to 500, file descriptor limit to 1024, process limit to 512.

FILES

       The default location of instances.conf is /etc/zorp/instances.conf. Defaults for zorpctl tunables can be specified in /etc/zorp/zorpctl.
