Programming :: C - Check If An Input Char Contain Numbers?
Mar 19, 2010I would like to create a small C tool. I encounter a problem of how to make a function to check an input chars contains numbers (started from the second element).
Some samples:
char *mychar= "a3547"; (The result of function checking this is true)
char *another_char = "t6548"; (The result of function checking this is true)
char *next_char = "appl3"; (The result of function checking this is false)
char *new_char = "b1aa3"; (The result of function checking this is false)

Programming :: Multiple Input Into Seq Command From Pipe - Single Column Unique Numbers
May 13, 2011Have this script which is reading in a series of files, one at a time with while-do-done loop, each file goes through various greps/awk's where this info is then saved to various files for later use. i.e....
Script is being run on Linux Red Hat,
In one of the grep/awk's the output (currently) are 2 columns (min max), i.e....| awk '{print $1, $2}' | sort -u which outputs (e.g.)
The number of "min max" pairs varies from file to file. Want to output a single column of unique numbers from the min max pairs & get the number of them for input to a file...i.e...
Where <PROCESS> is some process/technique that will generate a single column of integers (increment of 1) to pipe into the next one (sort -u)
i.e. (example from above)
Have tried command seq - only works for single pair input i.e.
Is there any command like seq etc which will output a single column based on a input of min max numbers (increment 1) to pipe onwards to next command?

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.

General :: Parsing Columns In Bash / Extract The First Set Of Numbers And Get Them To Appear Only Once?

Sep 11, 2010I've got an Emprex 3009URF remote control which I'm using to run XBMC and whilst it works fine for the most part there are a couple of things that I can do with a keyboard/mouse that I'm unable to do with the remote, for instance "right clicking" with the mouse that brings up a context menu, that is totally inaccessible from the remote.
Some things I was able to fix by editing .xsessionrc as instructed by another post elsewhere on the tubes, in the format of:
xmodmap -display :0 -e keycode 127 = space
however I don't know how to find the keycode and I don't know how to map that to a right click event.
General :: Bourne Shell Input From File Using - Then Return Control To User?
May 5, 2011I have a program that I run from the terminal that requires manual input (it's matlab in mex debugging mode, matlab -Dgdb, which starts the GNU C debugger with its own custom settings).
Every time I run this program I always type in the same few commands in the program's interactive shell before I actually start working (for example: run -nojvm; stop at mexFunction; continue). I want to avoid typing these commands and I thought I could do this with shell scripting, saving the commands in the mycommands file, then running: myprogram < mycommands
The problem is that this runs all the commands and then exits the program. I want it to run the commands and return control to me so I can run my commands. Is there a way to tell the shell to use a file or a string as the input to a program then immediately return control to the user without the exiting the program?

Ubuntu Installation :: Toshiba Portege M750 - Cant Find Tablet Control Features To Change Input Devices
May 4, 2010Ubuntu is perfect for me, except that i have to dual boot sometimes to windows 7 for the one application that wont run in a virtual environment (LockDown Browser, and occasionally onenote). Except, i cant find tablet control features in Ubuntu, to change input devices (the touchscreen is awful, but I cant turn off the option to use finger as an input device. Also, when i boot to windows 7, the mouse track pad/left and right click doesn't work (they work in Ubuntu)? The keyboard does, and so does my stylus (which I have to use as a substitute)
View 7 Replies View RelatedGeneral :: [bash] Output Of One Script Is Input Of Another?
Mar 20, 2010Now, I have one script called "defcon" defcon gets the current DEFCON level and outputs it using echo.
Code:
#!/bin/bash
DEFCON=`curl -s http://members.tripod.com/~Swat_25/defcon.html | sed -n '/^$/!{s/<[^>]*>//g;p;}' | sed '/^$/d' | grep '[12345]$'`
echo "The current DEFCON level is $DEFCON"
The second script ("tweet") updates my twitter account.
Code:
#!/bin/bash
curl -s -u USER:PASS -d status="$@" http://twitter.com/statuses/update.xml > /dev/null
What I want to do is be able to update my twitter account with the current defcon status (this is really more of a learning thing than something I actually want to be doing). The original script for tweet replaced $@ with $1, but if I use:
tweet `defcon`
it only uses the first word in the string, similarly if I used $2 or $3.So I changed it to $@. The normal function still works, but typing:
tweet `defcon`
updates twitter with nothing.
EDIT I should mention the /dev/null is there to catch the output of curl, otherwise it won't run silently. It still updates twitter normally with the send to /dev/null

Programming :: User Input Bash Script

However, if the user inputs a directory and finds its size then inputs another directory then wants to quit, the script asks the user numerous times if he wants to quit!! The script won't exit until the number of times the user looks at a directory is reached! What gives?

May 7, 2010As I'm starting to learn bash scripting I'm trying to automatize some tasks I usually perform. I have a notification mail I need to send several times a day. It has this structure:

You need to contact the following people:

To replace "user", I found this:
Code:
read -p "Please enter username: " username
echo "Dear $username,"
Which probe to be very useful with other simple notifications like this. But I don't know how to manage the email addresses as they are usually more than one and could vary from 1 to 10. They should appear one above the other. I found this: "Here is a little work around. The only thing the user needs to do is hit enter without anything else on a line and it will close out"
Code:
#!/usr/bin/ksh
word=a
until [[ $word = "" ]];do

I tried to use it and modify for my needs but I failed, I don't realize yet how can I use it. If possible, I would like to use the until loop like the above example just for learning purposes but any other form will be accepted as well.
Programming :: Working With User Input In Bash
Jun 2, 2009I've been using python/bash to help myself automate things for a long time, however I am curious. One reason I use python more is because I don't quite know how to work with user input in Bash, such as getting it to ask for input and wait, and then placing that user input into a command.
Here's an example of a script I use from time to time for converting OGG video files into AVI.
How could I write this same script in Bash? Keep in mind I am mostly self taught, so I am by no means an expert programmer.

Software :: Bash Script: Wait For Input From Kdialog Before Doing Sth?
May 27, 2011The goal of the script is the following:Whenever I leave my house, my wife comes to my computer to check her mails (She has two computers of her own but they have a dangerous operating system, so they have been banned from the internet).She shuts down qbittorrent so as to download all her mails, and she forgets to execute it again on 98% of the times. End result: my computer is sometimes turned on for 10 hours doing absolutely nothing.I had therefore two choices: a) get on my wife's nerves until she gets the problem or b) write a bash script.If you are married, you will understand that bash scripts are easier to deal with than spouses.Ergo, I wrote the following script:
