In the last Git Commands article, you have learned how to use Git options and what they can do. Today, we will extend our reach and discover everything there is to know about commonly used Git Commands. Git commands are used to access the Git working directory and connect it to our remote repository, by making changes, viewing different files, and many other possibilities! Once your project is set

僕がよく使うGitのコマンドの整理をしておこうと思った。 1. git clone リポジトリから取ってくる まずはcloneするよね。手元にあってちょうど良い感じなのがmakingさんのjsug-shopだったので、これで進めてみる。 $ git clone git@github.com:bufferings/jsug-shop.git Cloning into 'jsug-shop'... remote: Counting objects: 299, done. remote: Total 299 (delta 0), reused 0 (delta 0), pack-reused 299 Receiving objects: 100% (299/299), 427.05 KiB | 193.00 KiB/s, done.

CPU hardware information The cpu information includes details about the processor, like the architecture, vendor name, model, number of cores, speed of each core etc. There are quite a few commands on linux to get those details about the cpu. In this post we shall take a look at some of the commonly used commands that can be used to get details about the cpu. 1. /proc/cpuinfo The /proc/cpuinfo fil

Perhaps the biggest surprise to come from Microsoft’s Build developer conference last week was the Windows Subsystem for Linux (WSL). The system will ship as part of this summer’s Anniversary Update for Windows 10. WSL has two parts; there’s the core subsystem, which is already included in Insider Preview builds of the operating system, and then a package of software that Canonical will provide. T

In this post, we’re looking at one of the most successful source code management tools available today, Git. With every great tool, there is a CLI which compliments all the great features and options, which leads to a vast number of things you need to remember and be expected to recall within a keystrokes notice. Enter: the Git cheat sheet. Looking for a different Java cheat sheet? Be sure to chec

なんで相手に繋がらないの！？ サーバ管理していてよく起こる問題は、「なんで繋がらないの！？」ですよね。そこで、今回は基本的なネットワークをご紹介したいと思います。OSやツールのバージョンにより動作が異なりますので、それぞれ調べてみて頂ければと思います。今回は、Amazon Linux 2015.03を用いています。 ping 基本はpingですね。ICMPのにあるエコー要求/応答のpingを使って接続確認を行います。 $ ping yahoo.co.jp PING yahoo.co.jp (182.22.59.229) 56(84) bytes of data. 64 bytes from f1.top.vip.ssk.yahoo.co.jp (182.22.59.229): icmp_seq=1 ttl=54 time=4.84 ms 64 bytes from f1.top.vip.s

こんにちは。今回はLinuxのシステム情報を入手するコマンド特集です。システムの設定やハードの情報を入手する際に役立ちそうなコマンド（というかCUI操作）を独断と偏見でピックアップします。ディストロやバージョンによって設定ファイルやコマンドは変化しますので注意してくださいね。（本記事は2014年10月に加筆修正されました。） CUPの情報を得る まず手っ取り早く情報が欲しい時は以下のコマンドを打ってみてください。 lscpu 出力例 Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Address sizes: 48 bits physical, 48 bits virtual Byte Order: Little Endian CPU(s): 8 On-line CPU(s) list: 0-7 Vendor ID: Authenti

While dealing with big genetic data sets I often got stuck with limitation of programming languages in terms of reading big files. Also sometimes it is not convenient to load the data file in Python or R in order to perform few basic checks and exploratory analysis. Unix commands are pretty handy in these scenarios and often takes significantly less time in execution. Lets consider movie data set
