Remove Exif info in jpg image under command line

Exif, stands for Exchangeable image file format, which we usually use to recognize the camera manufacturer, model, exposure time in a digital photo, it is a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras (or digital devices in nowadays, like smart phones and tablets), scanners and other systems handling image and sound files recorded by digital cameras.

Exif in JPEG image example from Wikipedia: https://en.wikipedia.org/wiki/File:Konqueror_Exif_data.jpg

Exif can help us know more about the photos and audios, but may also leaks the valuable and privacy info if you don’t want to let others know that you just want to share pictures with others, it will also cost a small disk space, but uf you don’t need it or you don’t want it, it’s also a waste of disk space, so you may want to remove that info like me in some situation. Here is the steps to remove Exif under command line.

Install exiftool:

Make sure you can now use exiftool:

If you would like to see the current exist info, use this command, filename.jpg is the picture you want to manipulate:

Now you can remove Exif info:

By default, it will backup your file to filename_oringinal, like filename.jpg -> filename.jpg_original, so you don’t need to worry about the backup, if you don’t want it, you can also add parameter -overwrite_original to prevent to backup file been generated.

After you remove the Exif info, you will find the modified file be a little bit smaller now.

If you take a look at its info, you will find that there are only some basic info remaing:

That’s all.

rsync 只同步特定格式/副檔名檔案的方法

想要用 rsync 同步特定格式的檔案,最近比較沒空動腦認真想,只好 Google 找現成的答案,在 stackoverflowUbuntu forums 看到的方法,很實用:

http://ubuntuforums.org/showthread.php?t=763833&p=8546521#post8546521

https://stackoverflow.com/a/11111793

看 stackoverflow 那邊討論是寫 rsync 3.0.7 以前的版本的用法要這樣寫,那個 exclude 和 include 的順序有影響 :

不過我自己是沒特別測試過就是了,隨手翻了一下 change log 好像沒看到相關的說明:

所以不確定是不是真的從 rsync v3.0.7 改了用法還是怎麼樣,等哪天有空再來翻翻看 …

Copy / pipe text from command line to clipboard and vise versa

xclip is command line interface to X selections/clipboard that is designed to run on any system with any X11 implementation, with xclip, we can not easily manipulate the data on the clipboard under a terminal in X11, no need to open a file for just copy its content anymore, and no need to move the mouse to select the output and copy it anymore. Except xclip, there is also a similar program called xsel, google it if you are interested in.

The homepage of xclip:

It’s very to install xclip via apt-get under Debian / Ubuntu based GNU/Linux distros or via pkgng under FreeBSD:

So how to use it?

If you want to copy something to clipboard, just pipe to xclip like this:

Now you can paste it as usual.

If you want to show something from clipboard, just call xclip to output:

xclip will output to standard output (stdout), so you can pipe or redirect the result to other utility and do some works you want.

在 Windows 10 上面跑的 Ubuntu / bash …

上個月(2016/03)底,今年微軟 Build 大會最讓人震驚的消息,沒有之一,透過微軟跟 Canonical (開發 Ubuntu 的公司) 的合作,未來可以在 Windows 10 上面跑原生的 Ubuntu / bash,不是跑在虛擬機或使用模擬器、容器等技術,是原生的!有了這個重大的改變,或許未來都不需要使用到 cygwinmsysGnuWin 這種專案了?一時沒空把所有資訊都看完,先來整理一些筆記 …

這項更新目前已經有測試版可以玩了,正式的版本預計在今年夏天的 Windows 10 年度更新釋出,之後就會在 Windows 10 上面有一個完整的 Ubuntu user space 子細統,不但 Linux 上常見的 utilities 如 grep, sed, awk 等工具未來都可以直接跑在 Windows 10 上,甚至 Debian / Ubuntu 在使用的套件管理系統 apt 也都可以直接使用,不論是對於使用者或是開發者都提供了更大的彈性以及便利性,同時代表未來 Windows 對 Linux 或其他原先只能跑在 unix-like OS 的專案會更加的友善。

微軟現在甚至使用 GitHub 來當 BashOnWindows 的 issue tracker:

https://github.com/Microsoft/BashOnWindows/issues

然後也有一個在 uservoice 上面的討論、反應平台:

我從底下會提到的 Linux Command Line on Windows 影片,截了一些畫面出來:

可以看到 lsb_release -a 看到的是 Ubuntu 14.04.4 LTS:

示範一些常見的工具,例如 fdisk 、mount,還有貼上文字的功能:
