In order to define a global expansion, you need to use C-x a i g command sequence. The next time you enter ‘intl’ followed by the space key, GNU Emacs will automatically expand the same for you. It will prompt you with the message ‘Mode expansion for “intl”:’. You can then type the word ‘international’. If you would like to remove all abbreviations for the current session, you can use M-x kill-all-abbrevs followed by the Enter key. Suppose, you want to define a local abbreviation for ‘international’, you can type in ‘intl’ and use C-x a i l to define the expansion. The abbreviations can either be local or global.
Depending on the operating system this may include _RLD*, DYLD_*, LD_*, LDR_*, LIBPATH, SHLIB_PATH, and others. Note that the dynamic linker on most operating systems will remove variables that can control dynamic linking from the environment of setuid executables, including sudo. These type of variables are removed from the environment before sudo even begins execution and, as such, it is not possible for sudo to preserve them.
This is done to keep a user from creating his/her own timestamp with a bogus date on systems that allow users to give away files. Sudo will not honor timestamps set far in the future. Timestamps with a date greater than current_time + 2 * TIMEOUT will be ignored and sudo will log and complain.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes – that way only the great commands get tweeted.
“Implementing Spark like system in Haskell” was an interesting session by Yogesh Sajanikar on his attempt to create a DSL for map-reduce jobs. He did cover much of the internals in his implementation and the challenges faced. The hspark code is available at https://github.
Sudo 可以讓你切換身份來進行某項任務，例如上面的兩個範例。範例一中，我們的 root 使用 sshd 的權限去進行某項任務！ 要注意，因為我們無法使用『 su – sshd 』去切換系統帳號 (因為系統帳號的 shell 是 /sbin/nologin)， 這個時候 sudo 真是他 X 的好用了！立刻以 sshd 的權限在 /tmp 底下建立檔案！查閱一下檔案權限你就瞭解意義啦！ 至於範例二則更使用多重指令串 (透過分號 ; 來延續指令進行)，使用 sh -c 的方法來執行一連串的指令， 如此真是好方便！.
I am looking an easy way/command to find. There are many groups(root, wheel, adm etc) at server, and have users in it. How do I list all sudo users at CentOS server.

You can also copy the image area using the C-c C-a M-w keys, and paste the same using C-c C-a C-y or C-x r y shortcuts. If you want to cut an area, you can draw a rectangle around it using C-c C-a C-k key combination. To set the operation to erase text, you can use C-c C-a C-d key combination.

To finish defining the macro, you can use C-x ) or the F4 key. You can then type a series of keys that constitute the macro. Macros are recorded key strokes that can be stored and replayed. You can start defining a keyboard macro using C-x ( command or the F3 key. In order to execute the previous defined macro, you can use C-x e shortcut or F4.
It’s essential for day-in, day-out Linux work. Sudo enables users to run commands as root or another user, while simultaneously providing an audit trail of these commands. Qualys, a well-regarded security company, discovered this essential command — but only on systems with SELinux enabled — can be abused to give the user full root-user capabilities.
