I have a tab-delimited file that has over 200 million lines. What's the fastest way in linux to convert this to a csv file? This file does have multiple lines of header information which I'll need to strip out down the road, but the number of lines of header is known. I have seen suggestions for sed and gawk, but I wonder if there is a "preferred" choice.

Is there a limit of stack size of a process in linux? Or it depends on the RAM of the machine?

I love WinSCP for Windows. What are the best equivalent softwares for linux?
I tried to use sshfs to mount the remote file system on my local machine, but it is not as user friendly as simply launching a GUI, plus it seems to require root access on the client machine, which is not very convenient.
Of course command line tools such as scp are possible, but I am looking for a simple GUI.
Thanks!

is it bad to output many files to the same directory in unix/linux? I run thousands of jobs on a cluster and each outputs a file, to one directory. The upper bound here is around ~50,000 files. Can IO be limited in speed in light of this? If so, does the problem go away with a nested directory structure?
Thanks.

I'm planning on writing a program for Linux that uses text to speech and speech recognition. What are the best tools/libraries for this? Should I use Windows instead to be able to use better tools? The tools need to be easily callable from a console or C program.
On solaris i can run the pmap command on a core file to get the memory map of a crashed process. Unfortunately the pmap command available on HPUX and Linux doesn't provide this option. Any pointers how i can get this information on these platforms?

I have a Linux kernel module M1 which exports a symbol S1. When I insmod M1.ko, I can see S1 in /proc/kallsyms. I use S1 in another kernel module M2. When I compile and insert module M2, I get message in dmesg saying "Unknown symbol in module S1".
I am stumped. Can someone please tell me what is going wrong? I am using Ubuntu 9.10.
In the Linux kernel, is there a way to traverse down to the buffer_heads from within a module?
I can see how to get to struct bio (task_struct macro: current-bio). But how can I get to the buffer heads? The buffer_head struct holds some information I'd like to obtain at any point regarding physical block numbers.

Hello,
I don't like this ugly FileChooser layout in Linux.
This layout is used by any other program and is MUCH more beautiful.
Is this layout available in Java? If so, how?
Thanks
The Component Object Model (COM) is (or was...) the way in Windows to provide language-neutral software components.
There is any programming model in Linux/UNIX with the same philosophy of code reuse through binary components?
