Ubuntu :: Write A Base Script Which Will Divide An Argument By 10 And Then Use That Argument In Another Program?

Feb 23, 2010

I'm trying to write a base script which will divide an argument by 10 and then use that argument in another program. Since my argument can be a floating point number, I used bc to accomplish this. Here's an example of a simplified version of what I have so far:

<code>NUM=$(echo "scale=25;$1/10" | bc)
#make sure the first argument was formatted correctly
if [ $? -ne 0 ]

Ubuntu :: Echo Command To Output First Argument

Nov 5, 2010

In a script, when I enter "echo $1" the first argument is outputted. When I enter:
a=1
echo "$$a"

The output is just "$1", not the first argument. If I enter:
a=1
b=$$a
echo $b

The output is still "$1" and not the first argument. How can I get echo to output the first argument without use "$1" directly?

Red Hat :: Error Inserting MD5 - Invalid Argument

Mar 24, 2011

I am running Red Hat with 2.6.18-194.8.1.el5PAE kernel version. I am trying to run encryptfs to encrypt a partition on my hard drive. One of the kernel modules necessary is the md5.ko. I noticed it wasn't loaded in when doing an lsmod. I tried running modprobe md5 and it fails to load:

Fedora :: Argument Against Auto-mounting Of Other Partitions?

Apr 14, 2011

I boot several Redhat based distributions, Fedora 15, Fedora 14, CentOS, Scientific Linux, Redhat and occasionally something non-Redhat based like Ubuntu and Debian. Out of habit and preference I frequently set up partitions to be auto mounted at boot through fstab. Somewhere in time something went seriously wrong with the CentOS install. There are a ton of permission denied errors while booting CentOS (text style boot) mostly regarding shared libraries. The system will boot to the desktop and everything looks OK but some things don't work. I can't update the system because I have no network connection. I obviously can't get to the Internet or get e-mail. I can open a VT but can't log in as regular user or root.

Permission denied in both instances. I didn't make any drastic changes to the CentOS system, just minor tweaks. The culprit in my opinion is a combination of the fact that one of the other Linux systems did an SELinux relabel while booting and the CentOS partition was already mounted. Since the CentOS partition was mounted it too was relabeled. I can't prove this. If there's a way to prove it then I just don't have the skills or knowledge to do so. It's basically a theory based on what I know I've done with the several installed distributions. This is not a rant nor is it a request for help. Just a comment. An assumption, hopefully a correct assumption. The CentOS install was working flawlessly until something happened and I think that something was the SELinux relabel.

Programming :: Making A 1 Command Line Argument?

Jun 8, 2010

I need to write a script that will take 1 command line argument. The argument will be a username. The script will determine if the user exists on the system and will print an error if it does not. If the user does exist it will determine if the user is currently logged in, if the user is not logged in it will determine the last time the user logged in and display the file in the users home directory that was most recently modified.

Programming :: Passing The Char * Vector Argument?

Jun 19, 2010

I am trying to simulate a shell. So what I do is checking of having the parameters from standard input, suc as "/bin/ls -l /home/france/Documents", and then passing them to function execute, which at some point calls execvp(argv[0],argv)The problem is that I don't succeed in using these arguments, while if I call execvp(paramList[0],paramList) it works!!!! Where paramList is exactly what I would put on standard input, but defined statically.

Code:

#include<unistd.h>
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
