General :: Shifting Positional Parameter Inside A Function?

Oct 19, 2010

I need to shift the positional parameters of a script inside a function, but any call to "shift 1" inside a function shifts only the parameters of that function. Is there some way of accomplishing that? I tried another approach using an alias. The problem is that I have to take the result of the alias. So I call in my script:

Code:

var=$(shiftalias)

At first time, it works correctly, but after that it does not shift the parameters anymore.

Ubuntu :: Change Boot Parameters In Grub2?

Aug 10, 2011

I have a mental block whenever I'm confronted with anything to do with grub2. Changing things in menu.lst was SO much simpler....

I want to include the command 'acpi=off' - but where do I put it? Can I change the detail of an existing grub entry in this way, or do I have to create a complete custom menu entry in grub.d and include it in that?

Ubuntu :: Change Queue Parameters Dynamically During The Simulation Under NS2 Simulator?

Sep 19, 2010

I want to change parameters of a RED queue during the simulation but it seems that some parameters can be modified only before starting the simulation, not dynamically, while the simulation is in progress. For example the following subroutines works before $ns run command but it do not change the behavior of the queue during the simulation( I want to change maxthresh_ and thresh_ after $ns

run command): Code: proc setREDParameters { redQueue MINth MAXth PER_MaxP Wq } {
$redQueue set thresh_ $MINth
$redQueue set maxthresh_ $MAXth

General :: Custom TCP Parameters For Multiple Interfaces - Change The Default Values

Feb 16, 2011

My question is about TCP parameters in Linux. By now, I want to change the default values of:

Initial Timeout
ACK Delay
Idle Connection Timeout

I have a Linux Box with kernel 2.6.x and 2 ethernet interfaces. I know TCP is a stack that doesn't have anything to do with ethernet devices. Said that, the question: is there a way to set custom values for each interface? For example, a server listening to connections in eth0 would use one value for Idle Connection Timeout and another server listening to connections in eth1 could use a different value for that parameter.

Ubuntu :: Creating Link To A .java File With Parameters

Oct 24, 2010

I have a Java program (minecraft server) that needs to be run from the command line. The code is:

Code:
java -Xmx512M -Xms512M -jar minecraft_server.jar nogui

To make life easy (i've got the java file in a folder on the desktop) I want to have a shortcut (or similar) sitting on the desktop. I've tried

Code:
ln 'java -Xmx512M -Xms512M -jar minecraft_server.jar nogui' ./../minesraftserver

with single and double quotes but my unix command line skills are pretty basic and this is obviously incorrect.

Security :: Change Values Of Parameters For Iptables "recent" Match?

Dec 8, 2010

According to the man page, the "recent" match of iptables accepts certain parameters (e.g. "ip_list_tot"). I'd like to change the values of some of them.
All the solutions found on the web were about changing parameters for module, but my kernel was compiled without modules support (such that it can be used for installation booting as well).
How can I change the match parameters for my non-modular kernel ?

General :: Shell Script File - Pass Multiple Parameters To Interpreter?

Feb 2, 2011

I have a Python script that I run which needs to execute under a special environment, so I would run the program like so from my working directory (~/project/src):

python manage.py shell

This opens up an interactive shell for me to start typing my own commands.I have another set of administrative activities that I would like to house in another directory (~/project/admin). The manage.py is really finicky about running from the working directory. So, to make this whole thing work, I made a script which starts off like so:

#!/usr/bin/python ../src/manage.py shell

There are a couple problems with this. The first is that it doesn't work:

/usr/bin/python: can't open file '"/../src/manage.py" shell': [Errno 2] No such file or directory

How do you specify multiple parameters to the interpreter?How do I change the working directory?

OpenSUSE :: Check What Is Inside The File?

Jul 29, 2011

I have a custom file, that is created by a X (not known) program. I would like to "try" to read one of the files it creates. Of course one way is to try to open it from c or java and try to see what is inside the file. For that I have to do a few retries with different data types.

Thus I was thinking if there is any program, that can facilitate this checking by reading the file with all the different ways fast.
