Kernel 2.6, Slackware 12.0
mkisofs 2.01
I do 'mkisofs -iso-level 1 -o image John Smith.txt'. Only an example. When I mount image, ls outputs john_smi.txt. So it has shorten to 8.3 and translated ' ' into '_'. This is in accordance with the manual, although it doesn't say the conversion will be done.

-iso-level level
.........................
With all iso9660 levels from 1..3, all filenames are restricted to upper case letters, numbers and the underscore (_).
...........................
However, as it did not reject the file name, it should have converted it to all upper case, it seems to me. And -iso-level 2|3 does the same thing.
Code:

I want to display 4 options using the case command and refresh the screen when options 1 and 2 are chosen (no changes to the options and you get asked again to chose option), but give a message for option 3 and exit on option 4.

I am working with a third party that use windows to compile. When we port that code I am running into a lot of case issues where the includes are not case sensitive. Is there any option in GCC to make it case insensitive. I know its a long shot, as I have done reading and does not seem so.

I've started dabbling with the case statement in order to pass some option's arguments into variables. I do not think I am doing this right.
Code:
usage() {
echo "Usage: $0 [-z|--snooze] [-c|--channel] [-p|--playlist]
[-m|--message] [-v|--mpcvolume]"
[code]....
As you can see, I want to pass arguments depending on the option(s) chosen by the user; ie. --snooze, or --channel. By default, if no options are chosen, I'll display a usage message; though in the future I'll provide some sane defaults. I'd like to create a case statement to handle passing arguments to any number of options; something like:
Code:
wakethehellup.sh --snooze 20 --message 'wake up!'
and for the other arguments, it would have a default set. The case statement I provided fails with a syntax error "syntax error near unexpected token `$2'" near the '--snooze' in the statement, so I take it you can't pass a parameter in this way; but I'm confused as to how I'm supposed to pass different parameters to different options without the options being confused as parameters.
I am trying to do a search for the certain books, and I am trying to make it case insensitive. what I have come up with so far is this :
Code:
Database.txt
RETARDED MONKEY:RACHEAL ABRAHAML:30:30:20
GOLD:FATIN:23.20:12:3
StUPiD:JERLYN:20:40:3
Code:
echo -n "Title: "
read Title
echo -n "Author:"
read Author
echo ""
valuecheck='grep -i "$Title" Database.txt | grep -i "$Author" | awk -F":" '{ print $1}''
echo $valuecheck
if [ $Title = $valuecheck ] ; then
echo "HOHOHO"
else
echo "too bad"
fi
The issue which I am having is that, when it does the search for the correct row to be inputted into valuecheck, it will input the value as written in the database, which is in Uppercase. For this case, if I type in stupid for $Title and jerlyn for $Author, it searches the correct row, but the awk will print "STUPID" into the variable as that is what is written in the database. So how can I make my if statement case insensitive? Currently it reads like this:
Code:
if [ $Title = $valuecheck ] ; then
which means
if [stupid = StUPiD ] ; then
How can I make the if statement it case insensitive to allow it to display "HOHOHO"
Few months back I learnt a *few* concepts about bits/bytes and started writing a program for bit packing in C++. Now that program has grown upto 600 lines and I am still working on it. Yesterday I realized I missed some special cases due to which the program was malfunctioning. Now I have modified the program and it is working properly but I think If I would have designed all the possible test cases before writing the code, I would have finished the program long ago.
I. What is proper way to design the test cases before coding?
II. How should I make sure that I do not miss any cases while making the test case doc. ?
III. Does writing test cases prior to coding solve messy code issues or should I consider something else ?
How do i make my strings case-insensitive while comparing them with an if statement?
View 2 Replies View RelatedI wasn't sure where to put this so if I need to move it just let me know.I have a strange problem that I cannot figure out. When I use gdb to debug our rpm-installed program, it says (no debugging symbols found) when it loads. Thing is, when I use nm on the program it can print the symbols, and even stranger is if I use gdb on the program before it is packed up by rpmbuild it loads the debug symbols just fine.Our program is built via the standard make using:GS=-g -Wall-pedantic and as I mentioned I can debug the resulting program. After the build, I package it up using:
cmd="rpmbuild -v -bb ptsnmp.spec --define "ver ${cmvc_release}" --define "rel ${cmvc_level}" --define "_topdir $rpmdir""When this package is installed via rpm, the binary on the machine shows all the debug info via nm, file shows it is not stripped:pt_snmp: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not strippedyet when I try to debug it I get the no debugging symbols found.This is really taxing my brain and I am sure I am just missing something
I am trying to access a generic netlink family to send messages from user-space to the kernel. I am using libnl example here [URL].. The problem is that I keep getting

View 3 Replies View Relatedi'am tring to use generic netlink and can't find function for blocking not busy waiting receive. I'll try to explain myself. Generic netlink receive mechanism based on callback function - when module receives something,this function invoked. But this is not so good if you need to send something and receive answer. I mean something like that :
sendmsg(); if(recvmsg() < 0) goto err; I need generic netlink recv() function, or some mechanism to implement it. I just want to stay in "recvmsg()" function until i have answer(until call_back function invoked).
I switched to the generic-pae kernal image, which works great, but update now wants to update both generic and generic-pae.
How can I set it up so that it only uses generic-pae?
If I try to deselect generic in synaptic it just wants to mark it again.
I'm using gmake (v3.81) to build some c executables. As the first step in the process I run the files through a preprocessor (for embedded SQL). The preprocessor completes successfully, but the gmake reports an error and discontinues buiding the remaining dependencies...
make *** [myfile.c] Error 4
which (according to /usr/include/asm-generic/errno-base.h) means "interrupted System Call". My preprocessor doesn't raise any signals, so I'm not sure what's causing this error.
I do have one question about the latest Ubuntu server edition 9.10. Currently I am using 8.04 on a server at home and have nothing but great things to say about it.
