But when I read some C code example using system call pipe() together with fork(), I wonder how they are implemented at the big picture level, including both unnamed and named pipes. It is often heard that "everything in Linux/Unix is a ...

I tried something like gunzip file.tar.gz | tar -tv but that ends with tar: /dev/rmt/0: No such file or directory and unzips the tar.gz to .tar which is undesired I only want to look inside them without modificat...

Typically, one sees find commands that look like this: $ find . -name foo.txt when the search is to begin from the current directory. I'm finding that on my machines (Ubuntu, Cygwin) I get the same results without the dot. Why is it typically included? Is it just a convention to be explicit, ...

I installed Ubuntu on an old laptop, alongside WinXP. Now I'm trying to download some updates and it says that I don't have enough free disk space - I need to free some more space on "/". Since there's plenty of room on the machine, I suppose it means that not enough space is allocated for the U...

I'am trying to debug a server that throws a lot of logs on stdout/stderr. I need to redirect only last n lines to a file. Something like a rotating buffer feature there in tcpdump -C & -W flags. It would be nice if I could view the log while the server is still running and throwing the logs (...

I recently asked a question that could be considered a duplicate. However, the wording of the question is very different and I think it can definitely aid people who are searching for such a problem. I believe this falls into the category of a good duplicate question; of the kind that Jeff Atwood...

Using the ncmpcpp MPD client, in the search function (F4) how can I add all the search results to the current playlist short of adding each item one-by-one?

Can I use simple interrupt handling code (i.e. using kernel loadable modules) to handle VIRQs thrown by Xen? I managed to introduce my own VIRQ using arch-specific ones, and wanna catch them in guest and handle them.

ext4.wiki.kernel.org makes it sound like e2fsck was simply renamed to e4fsck so that e4fsprogs and e2fsprogs could coexist without overlapping. However, there is no mention of any difference in the code of the command. The e2fsck man page makes no mention of ext4, but does mention that it works ...
