In Ubuntu (or else linux system), there are some directory in /sys/kernel/debug/tracing/events, but I don't know what these directory mean. For example, /sys/kernel/debug/tracing/events/block/block_bio_backmerge, I want some documents to describe this what they mean. Can u give me some relevant documents or some other advice to learn.
Thx.
It's easy to get by google, like this. And the brendangregg's blog is really deserve to read.

Can someone help me with the following problem. I want to make text appear and flow to the right at the same time like this website: https://www.wokine.com/en/ . How should my code look like?
There are a series of solutions to that and writing about them all in detail would take forever, I'm just going to share a few of my favourite libraries and a few resources on them.
AOS is in my opinion the nicest library doing what you want to do. It's on Github.
WOW.js is another library that does what you are looking for, but it has some strange licensing.
With a queck search I could also find ScrollMagic, I have no experience with that one.
Hope it helps get you started!
im going crazy trying to look for examples of unix domain socket usage on bash. I'm starting to think if it is possible at all, and thenI find people using them for netowrk stuff, i wanting merely for IPC locally, can someone facilitate me some example, resources, guidance or at least if its possible at all?
Is this so deep in the kernel that it can only be programmed C for example... I;ve seen some Python stuff i think tho...
Thanks.
I've decided to go off using bash, it would be a big big task and i dont have any real constrains, I have learn a lot of how linux works tho, in essence to be able to implement this would have to probaly modify some parts of the kernel...
Thanks everyone.
I'm having trouble with the library of DSNUTILB. I dont know what library it belongs to. I've been surfing the net but can't seem to find the answer to this. Can anyone help out? How to find the library? Thanks.
DSNUTILB is delivered by default in the SDSNLOAD dataset by IBM. Look in the appropriate SDSNLOAD dataset that is allocated by your DB2 subsystem.
I'm a newbie on Linux programming and I don't know exactly where I can get information of functions for example. There is a directory Documentations in my sources. But I can't find semaphore stuff there for example. Is there a documentation for all the function somewhere in the sources? Or not obligatorily?
The Linux Kernel Newbies site is a good point to start.
And, of course, the kernel itself is the best reference. To get started. Also have a look at kernel.org/doc. For semaphores, look at this page here.
In my initial days of using linux I usually had to search google to know the command for
doing a particular task. Once I have the command name, i can view its usage using man command-name.
Similarly I was thinking of some utility which can tell the command to do a particular task if the task to be done is specified as an argument and opens the man page for that command
e.g:
findUtilty "find all files in a directory"
output:
ls
find
I want to know if some utility of that kind exists, if so it will be very handy especially for newbies.
If not then i may like to implement it.
thanx,
Not as nice as you are asking about, but
apropos <keyword>
and
man -k <keyword>
can be very useful.
Parsing natural language is hard because there are thousands of ways to rephrase one sentence. Google does it best as far as I know. So, there is no such tool. There are handy and practical manuals that makes it easy to find the right tool for the job. Also, there is a huge community behind core-utils (and linux in general), so try both forums and IRC. Often, the latter is the fastest. And people tend to parse natural language as expected :)
apropos will do something like you suggest.
I guess it is: List of Unix utilities # Wikipedia
on Debian (and presumably derived systems) this is also useful:
sudo apt-cache search <keyword>
Few years ago NetBSD decided to rewrite its apropos. The new implementation does a full text search with results ranked in order of relevance. It comes close to what you have asked. See the output here
