How do i correctly use delimiter to take in only the strings on one line?
Something very handy to do in a Linux shell, is manipulating files and strings - essentially parsing data. Write a utility which will scan in a text file and search and replace strings. We also want to keep track of how many strings we've replaced.
I know that my command would look like this: <utility name> <filename> <stringToSearchFor> <stringToReplaceWith>
Code: #!/bin/bash

I made a string key-value mapping struct in C, and functions to add and remove entries. I would also like to write a function to read in this file format:
Code:
key: value
another: another value

I was wondering, what would be a good, open-source file format for a beginner in the field, like me, to start editing sound files? This file format would have to be well documented, preferibly open-source, lossless and, most of all, convertible to more popular file formats, such as mp3 or wav maybe. I would like to design my own sound effects through directly editing the binary sequence of a sound file. I imagine this editing would have the purpose of adjusting the voltage variations of the sound device's output in time. It would be perhaps something like a PC-controlled signal generator. I'm thinking I might be able to do this in linux with something like
Code:
$ dd if=mysound.raw of=/dev/audio
But then, which book or resource woule be a good and through explenation of the relationship between the bit sequence in mysound.raw and the signal function generated in the output of, say, my computer's sound card.

View 7 Replies View RelatedWhenever I open a folder with the default browser (Nautilus), it does a quick scan of the contents. This is not a problem for normal folders, but it becomes one when a music folder contains several thousand files (I haven't yet tried with folders containing large amounts of non-music files). In such instances Nautilus sits there scanning and I can hear the hard drive seeking for a good while before it presents me with the contents of said folder. My music folder, for instance, contains some five thousand ogg files, and I have to wait *counts* a full minute before it displays its contents. I tried telling it to never count the number of files in the options, but it didn't help. So far, the only solution I've found is to use pcmanfm instead, which apparently does no scan and displays my music folder practically as soon as I click on it. Still, I like Nautilus more for everything else, so I'd much rather use that instead.

View 5 Replies View RelatedI'm looking for some expert opinion on sed/script to work out the best way to transform one xml format into another however there are a few complexities around translation.
The extra complexities are to:
1) Take the start and stop time (YYYYMMDDHHMMSS) and convert to start time to unix time plus output the difference in seconds between both times.
2) Oid, tsid and sid are found by looking up an external file and finding the value against the channel. For example one of the lines in the file will be 2:806:27e2=channel1
Is there any way to write piped sed commands that can do this? If not, any ideas how the script should look like?
Input File
Code:
<programme start="20100910060000 +0100" stop="20100910061000 +0100" channel="channel1">
<title lang="en">This is the title</title>
<desc>This is the description</desc>
</programme>
Output File
Code:
<service oid="0002" tsid="0806" sid="27e2">
<event id="0">
<name lang="OFF" string="This is the title"/>
<text lang="OFF" string="This is the description"/>
<time start_time="1284098400" duration="600"/>
</event>
</service>

Code:

In C++ as subjected, can anyone throw me some light on how I can generic-ly format an integer value of 1 to a string value of 0001? 11 to 0011? and 111 to 0111? simply by just appending 0 in front and limiting the length of the string to 4?

View 10 Replies View RelatedI'm reading a book on assembly, and it talks a bit about the IEEE floating point format.
Quote:
To summarize, the following steps are used to convert a decimal number to IEEE single format: 1. The leading bit of the floating point format is 0 for a positive number and 1 for a negative number. 2. Write the unsigned number in binary. 3. Write the binary number in binary scientific notation f23.f22 ... f0 2^e, where f23 = 1. There are 24 fraction bits, but it is not necessary to write trailing 0's. 4. Add a bias of 127 to the exponent e. This sum, in binary form, is the next 8 bits of the answer, following the sign bit. (Adding a bias is an alternative to storing the exponent as a signed number.) 5. The fraction bits f22f21 ... f0 form the last 23 bits of the floating point number. The leading bit f23 (which is always 1) is dropped.

Request help with scanjet 3500c operation. xSane .996 in Ubuntu sees scanjet and scans. As soon as scan completes, the xSane windows(2) disappears and there are no copies in the intended save folder in Documents. Upon original attempt, the xsane windows had an additional third "Preview" window which has not returned since that first scan attempt?
One is not a computer guru by any imagination!
Info; the scanjet worked very well on the other "doze OS" and seems now, does not in the Ubuntu OS. In Doze, there was also a program for a HP PhotoSmart 3200 running and when I added the scanjet it might have been happy with that driver. Currently I do not have access to the driver disc for the 3200 with me. Too, it now takes ~45+ seconds for the scanjet to begin as compared to 2 - 3 seconds on doze.
Some internet self help searching seems to suggest the xSane 1.0.18 is the driver choice to use with the HP 3500c scanjet. When attempting to download, an archive "Failed" notice appears. I am a bit lost from here.
