Mar 31, 2011snappy title to grab attention. maybe not stupid, but bleeding difficult to use, talk about a non-obvious, non-intuitive interface; I want to enter a hex value, and have the calculator convert that to decimal. So, I use the pull-down, choose 'hexadecimal', enter the hex value, then change the pull down to 'decimal', expecting to see the decimal (base 10) value. What do I see? The display just adds the hexadecimal base to the end of the hex value I just wrote! Where's my decimal (base 10) number damn it? I can't for the life of me work it out.

Programming :: Bash: Convert Decimal To Minutes:seconds?

Programming :: If Statements With Decimal Places - Compare It To A Predefined Value
Aug 11, 2010I'm writing an if statement where a variable is a number such as 14.05 (this is actually a temperature) and I want to compare it to a predefined value, sample code below:
Code:
I have all sorts of errors regardless of how I do this (double quotes, square brackets). The best idea I've had is stripping off the decimal place so it's a 4 digit number (e.g warning=1503 and DEV_TMP=1405) however this seems a little unnescessary and I'm sure there's an easier way of achieving the same thing.

May 10, 2010 I'm working with a rather large file of data taking from a tracking program on my phone, and trying to pull only the longitude and latitude from it. Any given line in the data looks more or less like this:
{"lon":-122.3083848,"time":1.273515839496E9,"source":"skyhook","nap":28,"altitude":0,"name":"location","hpe" :29,"bearing":0,"ncell":0,"lat":47.6544453}
I've run it through this command:
grep skyhook log-2010-05-10_18-17-28.json | cut -d"," -f1,10
to get this:
{"lon":-122.30872015,"lat":47.65812201}
{"lon":-122.3076686,"lat":47.6569975}

{"lon":-122.3096168,"lat":47.656218}
{"lon":-122.3096285,"lat":47.656206}
Which is a lot nicer, but I would prefer not to have to hand remove the non-number characters by hand since there are thousands of data points. what I could do to get it to just be longitude and latitude in 'number number' format?

General :: What Command Run To Determine The IP Numbers?
Apr 20, 2011Firstly I would like to say that Linux is very cool, especially the CLI. I have been trying to learn how to do some things in Fedora after being told Fedora was a good distro to get my feet wet. I have run into some issues and cant seem to find any answers. What Linux utility can be configured to automatically save the current logs?
How does your Fedora get an IP number? What IP numbers has your Fedora been assigned since it was installed (based on the logs you have)? What command did you run to determine the IP numbers? What command would you run to determine the number of times a user successfully used "su"? What command would you run to determine the number of times a user unsuccessfully used "su"? Having some issues with the file system as your Fedora boots up.

Mar 1, 2011I am trying find files in a directory that contain numbers. I have tried ls /etc *[0-9]* but that doesn't work. If I cd to /etc and run ls *[0-9]* it almost works but it also includes results from within files. My last thought was to try: find /etc [0-9] -type f but this does not work either. My second problem is that I am trying to get list of files in a directory that were changed less than 10 hours ago, using grep, while leaving out directories. I am completely stuck with the second problem.

General :: Using Rpm Command To Count The Numbers Of License
Feb 27, 2010I am a newbie in Linux. Here is my question....
Create the file ~/license_counts, which tables the number of occurrences of packages which are licensed under a given license, for the top 5 most commonly used licenses, sorted in numerically descending order. If performed correctly, your file should be formatted similarly to the following. (Do not be concerned if the actual counts or license names are different. Also, you might notice logically similar licenses, such as LGPL/GPL and GPL/LGPL. Do not make any attempt to combine them into a single entry.)

General :: Assign Port Numbers Against Interface (LAN Card)
Apr 22, 2010I am using RHEL 5. In my Linux Box I have two Lan cards (eth0 and eth1). "eth0" is connected with network 192.168.10.0 and "eth1" is connected with network 192.168.11.0. Both Network are inter connected via routing. Now I want a situation where, I want to dedicatedly assign some port numbers against a lan card. Like eth0 will be assigned for ssh (22) and eth1 is assigned for telnet (23). So that, when a user connect to 22 port then he/she is connected to the server through eth0 , and when a user connect 23 port then he/she is connected to the server through eth1. Is it possible to do using iptables or other?
View 2 Replies View RelatedGeneral :: DU Style Directory Listing With File Numbers
Sep 6, 2010Is there a command to return a recursive listing of sub-directories and the number of files in them? I have found plenty of ways to give me the total number of files in a directory structure, but none that gives a list of the sub-directories with the number of files in them. "du" gives me a listing of directories with their sizes, but I couldn't find an option (or any other way) to give me the number of files as well. Ideally, I'd like to get list with "Size" "Files" "Dir name" - And the order of the columns doesn't matter. Is there a "simple" command line solution or do I need a shell script for that?

General :: Line Numbers To Html In Mixed Content?

Sample file:
Code:

1 If war is ever
2 legal, then peace
3 is sometimes
4 sinful.
Text without numbers toom I need the numbers to be <a name tags where the id is the letter x and the number that is at the beginning of the line:
