Q: Count total number of files in particular directory with specific extension

I want to count the total number of files in particular directory that ends with ".mp4" extension. I am getting following command: ls -F |grep -v / | wc -l It count all the files in particular directory, but I want the count of files that end with .mp4 extension. Is there any Ubuntu command ...

command-line ls

@Seth I don't understand him, why is he interested other's answer.

Seth

He's just being picky because your commands are very similar to his.

cleaned the comments.

xiaodongjie

@Seth Thanks. In fact, I editing same time.

okey...

Is anyone available to help me push a bzr branch to launchpad?

Web page says You can push the branch directly to Launchpad with the command:

But when issuing the command, I get bzr: ERROR: Not a branch: "/home/username"

Braiam

bzr branches?

actually, are you inside the directory where the repository is?

xiaodongjie

@Seth and it answer was voted down. I don't know the reason.

chaskes

I am in the directory containing the repository

xiaodongjie

I have many experiences of bash, python, C programming in Ubuntu.

Seth

@chaskes you have to go into the repository.

It needs to access files within it.

@xiaodongjie People downvote for lots of reasons and they aren't required to tell you.

chaskes

1:35 AM

just tried that too!

Seth

FULL terminal output please :)

chaskes

bzr: ERROR: Not a branch: "/home/eric/".

xiaodongjie

@Oh, the results?

chaskes

wait, just got it to work

simple mistake: forgot I moved the branch into a sub-folder

thanks @seth @Braiam

ok, my change is not there (first time with bzr)

Nathan Osman

chaskes

1:45 AM

@seth obviously forgot to commit the change before pushing it. took care of it.

Seth

2:04 AM

@chaskes Oh cool. Sorry I, uh, ahem, got busy ;)

chaskes

Well, good job then.

Seth

@NathanOsman lol. I see you changed your gravatar.

@chaskes LOL

Nathan Osman

Yes, I did.

Seth

He looks business like. In a good way :)

Nathan Osman

I'm not sure I like the color balance. But yeah, the tie makes it look like he knows what he's doing.

Lucio

@NathanOsman?

Nathan Osman

Yes, it's me.

Lucio

same one too?

Seth

No, it's a different one ;P

(jk)

Nathan Osman

Same what?

Lucio

Penguin

What'd you think we were talking about?

:O

Strange, Twitter now looks like GitHub :/

Seth

2:19 AM

@Lucio Same Nathan.

Lucio

yep, cooler one

Nathan Osman

Yeah, Twitter just recently changed profile pages.

Seth

I meant, I thought you were asking if it was the same Nathan.

Nathan Osman

I still say it looks like Facebook :P

Richard

I wanna learn a programming language

Nathan Osman

2:21 AM

I recommend Python.

Lucio

@Richard go

@NathanOsman not mine. At least I can't see it :S

Seth

@Lucio Go what?

Nathan Osman

@Lucio Don't you see a banner if you visit your own profile page?

@Seth The language, Go.

Lucio

@NathanOsman YES

Seth

Oh..

I recommend Python too.

Lucio

2:22 AM

A giant fuck you @twitter on this. #Redesign #Profile #NewTwitter http://t.co/YZ36HxMeRt

Go (programming language)

Go, also called golang, is a programming language initially developed at Google in 2007 by Robert Griesemer, Rob Pike, and Ken Thompson. It is a statically-typed language with syntax loosely derived from that of C, adding garbage collected memory management, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library. The language was announced in November 2009 and is now used in some of Google's production systems. Go's "gc" compiler targets the Linux, Mac OS X, FreeBSD, OpenBSD, Plan 9, and Mi...

Seth

I've heard Ruby wasn't so bad either.

Lucio

Are you starting on the development/technology industry? Go with Python http://www.markshuttleworth.com/archives/1363 #TheFutureIsMobile

Yes, I don't want to write things again. :P

Changing from issue, I have one doubt

@NathanOsman What do you do if you find that a User History has been missed on the project design?

Lets say, in the half of a spring.

Nathan Osman

User history? Where?

Richard

@NathanOsman smells like C... I dived in to that but realized it's probably a little dated

chaskes

2:27 AM

C is not dated, but not recommended as a first language

Nathan Osman

^--- this

Lucio

@NathanOsman On a scrum project

chaskes

Learning Python 5th ed O'Reilly may be a little hard for a true beginner. A good book is called something like Learning Computer Science Principles using Python, 2nd ed.

Nathan Osman

@Lucio I'm not sure I understand the question.

Lucio

@chaskes that sounds like a though book

Seth

2:29 AM

Hm, I'm going to have to try changing my graphics drivers. brb and wish me luck.

Lucio

I hope to see you soon, not writing questions ;)

Seth

lol

Hopefully :)

Nathan Osman

@Seth Nvidia or AMD?

Richard

@Seth If you're NVidia, good luck. If you're AMD, here's a screwdriver just in case...

Seth

I'm on Nvidia.

Nathan Osman

2:30 AM

Ah, you'll be fine then.

chaskes

tough? no. thorough, probably. too often beginners get taught syntax but nothing about how a computer really works

Lucio

@NathanOsman On a scrum project (using "Agile" methodologies), you set User Histories at the beginning. Then you start with the sprints. So what if you found out in the middle of a sprint that a UH has been missed?

Seth

Last time I tried (early Saucy) only one driver worked, but it isn't letting me change the brightness anymore :-/

Nathan Osman

@Lucio I'm afraid I'm not an expert on scrum :(

Lucio

Oh, ok.

chaskes

2:32 AM

@Lucio Did you see my tweet from a couple of minutes ago?

Nathan Osman

@chaskes Right on. Instead of understanding the concepts and paradigms of the language, beginners just end up memorizing a bunch of syntax. They can tell you what the <=> operator does but they don't know how to organize classes logically.

Seth

Hm, 331 or 331-updates first?

Lucio

mmmm- not

@Seth ouch

chaskes

@NathanOsman And then the jump to real world code is huge...

Richard

@chaskes I've gotten into that a little bit. Or at least I think I have. Building circuits, constructing an 8080, learning QBasic, programming a STAMP...

Lucio

2:33 AM

@chaskes :O

Nathan Osman

I'm working on a series of articles describing basic compiler theory.

Watch for it in the future - it should be good :P

Richard

@NathanOsman hooray (:

Lucio

@NathanOsman that is ok

chaskes

@Lucio Well, I'm pretty excited. There was a bug question awhile back and I just proposed a merge to fix it. First time after using Ubuntu for 2 years (and a history of Win32 programming)

Lucio

right, that is why I found it strange

Too much Win* :P

chaskes

2:36 AM

@Richard All good stuff.

@Lucio Now I feel that I understand Linux at the user/admin level enough to start really digging into the code.

Lucio

That is the goal of all of us :)

Good for you!
