I'm trying to write a batch file that does a few things... having trouble with it.
I can't find any examples to help me, but what I need is...
run 3rd party program to create 1 .hex file
load that and 2 other .hex files into a microcontroller
in windows 2000 and above, you cannot do this. due to the limitations of batch.
in DOS you would be able to, with the APPEND command, but it doesn't exist in new operating systems.
Bill Gates just took it out.

I'm a newbie on linux and I was planning to use logrotate so that my log files which generate inside a radio file system, would not getting larger size and cause any memory issue.
but as can see from below, this configuration is set at logrotate.conf file in linux, then I am confused and wonder is it possible to add this thing as a "coding style" in my C files so that it work on my radio which is running Linux system.
The radio don't have this logrotate thing under /etc/logrotate.d path after all. I also unable to install any logrotate or execute the command "man logroate", it tells : no manual entry for 'logrotate'.
/var/logs/*.log {
hourly
missingok
rotate 24
compress
create
}
Can it be called like normal function such as fclose() or fopen() in .C files?
If it can be used in C files, what is the correct way to configure the parameter?
I think you misinterpreted how logrotate work: It only work with files created by service/application on host machine.
For example on your linux machine you are running mailing server postfix (base on config you posted):
Postfix service filling log file /var/log/postfix.log
Logrotate take every hour postfix.log and create compressed file postfix.1
Increment number of already existing archive files
Logrotate keep 24 compressed files (= 1 day)
In you case you have to setup application logging to save log files and then you can apply logrotate to it.
Logrotate man page can be found here
Curiosity is one of my personal keys. I got a folder of an executable c application, this folder include many files some are files.so , files.ini and other files.lz and I decided to try do some kind of reverse engineering, so I have used a reverse engineering online tool for the files.so and files.ini are already opened via notepad as we all know, but now my problem is about opening files.lz, which i already know that it contains libraries to be used for functions on files.so
This is what i want to know and to have some help in it how can I decompress it via a desktop tool or even an online tool?
Should be Lzip.
When you are in the linux-world, one very usefull commands is file:
$ file myFile.lz
myFile.lz: lzip compressed data, version: 1
We have a bootable USB stick that works perfectly. It will boot, ask the user for some options, then write files to the hard drive accordingly. We did this by using rufus-2.1, throwing freedos into the USB stick, and basically hijacking autoexec.bat. Autoexec.bat now executes some separate .bat scripts based on user input.
The problem is, we now want to have an option to allow users to burn an iso to a cd or dvd. We've been trying to create an image of the USB stick and burn it to a DVD.
We found plenty of information on this subject, but nothing has worked. We started by extracting the bootimage from various bootable iso files using imgburn. None of these worked. We tried extracting the bootimage from our USB stick, and that also didn't work.
Next we tried WinImage. We extracted the boot information from boot98.exe, hijacked autoexec.exe, created a new image and injected the files. We saved the files as a bootimage and tried the above method again, which also didn't work.
Is there perhaps a more straightforward way to execute DOS .bat scripts through cd/dvd boot? We'd be open to something other than DOS as well, as long as it can write files to a hard drive based on user input through a simple boot interface.
Note: The computer itself does not contain an operating system.
Thanks.
We found a very slick setup that does what we need. Unfortunately, the CD-ROM drivers do not work properly on modern DVD drives. Using this method, it should be possible to put all the scripts directly in autoexec.bat and run commands directly on the "simulated" floppy drive. For whatever reason, we can boot from the "floppy" section of the CD-ROM, but it cannot copy files from A: to C:. I believe we are very close, but no cigar.

First method that actually produced a bootable CD and allowed scripts to be run by a choice entered by the user.
I have a random number thats generated and placed in a text file. i would like that file to be saved automaticaly to a USB drive only.
Is there a way in batch to ensure that the file is saved to USB only?
The simple answer is you can't. You will need to use a real programming language, or maybe vbscript at the very least, and even then it's very hard to ensure you are actually getting real USB drives.
See here and here for some vb samples.
Then if you do, you can use batch to call the script using cscript.exe.
I am looking to write a program that will extract the contents of an RPM file and do some validation checks. I'll be using Qt for the interface so that the program can be run in Windows and Linux.
Are there any suggestions for extracting the contents for an RPM file on Windows? I would prefer a C library, but other suggestions are welcome also.
rpmlib looks like what you are after.
