Our assignment is to take in two numbers and add them. While the inputs will always be numbers, we are to inform the user if they are doing it wrong. My code:
[Code]....
The code worked fine before I tried to idiot-proof it. I'll probably end up nesting the if statements checking if the first two inputs are not null, but I'm more annoyed at why the script isn't working.
as a result of a find command, i have
852065 72: /bin/gunzip
852065 72: /bin/gzip
852065 72: /bin/zcat
(the first column is inode number and the second is size if you're curious)
I want to be able to format it in a way such that:
852065 72:
/bin/gunzip
/bin/gzip
/bin/zcat
I know I can get the bottom half using awk- but I can't figure out how to extract the first set of numbers and get them to appear only once
I have to read a couple of numbers from a random.txt file. In this .txt file there are random numbers. They are separated by a space. Example if you opened test.txt:
test.txt :1 6 1 3 6 8 10 2 4
I would like to read those numbers using CAT and store them into an array:
numlen=${#num[*]} - (must be like this because it is a part of a larger program)
I'm making an bash script.
As input you can input different numbers from 1 to 3.
Depending from the input a text shows up.
For eg: $NUMBEROFPASSES=6.19 to round up I use NUMBEROFPASSES=$(printf %.0f $NUMBEROFPASSES) What I need to do is round up from eg: 6.10 to be 7 and if lower than 6.10 round down to 6

View 12 Replies View Related 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:

Firstly 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.
Any way to show the permissions with numbers (777) instead of with letters (drwxrwxrwx) using "ls" command or any other command ?
View 2 Replies View RelatedI 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.

I 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.)

I 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 RelatedIs 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?

I am trying to find a way to replace a set of sequential numbers in a file with a different sequence using sed.
