At—At, Batch—Execute Commands at a Later Time
at—at, batch—execute commands at a later time at [–csm] [–f script] [–qqueue] time [date] [+ increment] at –l [ job...] at –r job... batch at and batch read commands from standard input to be executed at a later time. at allows you to specify when the commands should be executed, while jobs queued with batch will execute when system load level permits. Executes commands read from stdin or a file at some later time. Unless redirected, the output is mailed to the user. Example A.1 1 at 6:30am Dec 12 < program 2 at noon tomorrow < program 3 at 1945 pm August 9 < program 4 at now + 3 hours < program 5 at 8:30am Jan 4 < program 6 at -r 83883555320.a EXPLANATION 1. At 6:30 in the morning on December 12th, start the job. 2. At noon tomorrow start the job. 3. At 7:45 in the evening on August 9th, start the job. 4. In three hours start the job. 5. At 8:30 in the morning of January 4th, start the job. 6. Removes previously scheduled job 83883555320.a. awk—pattern scanning and processing language awk [ –fprogram–file ] [ –Fc ] [ prog ] [ parameters ] [ filename...] awk scans each input filename for lines that match any of a set of patterns specified in prog. Example A.2 1 awk '{print $1, $2}' file 2 awk '/John/{print $3, $4}' file 3 awk -F: '{print $3}' /etc/passwd 4 date | awk '{print $6}' EXPLANATION 1. Prints the first two fields of file where fields are separated by whitespace. 2. Prints fields 3 and 4 if the pattern John is found. -

Program #6: Word Count
CSc 227 — Program Design and Development Spring 2014 (McCann) http://www.cs.arizona.edu/classes/cs227/spring14/ Program #6: Word Count Due Date: March 11 th, 2014, at 9:00 p.m. MST Overview: The UNIX operating system (and its variants, of which Linux is one) includes quite a few useful utility programs. One of those is wc, which is short for Word Count. The purpose of wc is to give users an easy way to determine the size of a text file in terms of the number of lines, words, and bytes it contains. (It can do a bit more, but that’s all of the functionality that we are concerned with for this assignment.) Counting lines is done by looking for “end of line” characters (\n (ASCII 10) for UNIX text files, or the pair \r\n (ASCII 13 and 10) for Windows/DOS text files). Counting words is also straight–forward: Any sequence of characters not interrupted by “whitespace” (spaces, tabs, end–of–line characters) is a word. Of course, whitespace characters are characters, and need to be counted as such. A problem with wc is that it generates a very minimal output format. Here’s an example of what wc produces on a Linux system when asked to count the content of a pair of files; we can do better! $ wc prog6a.dat prog6b.dat 2 6 38 prog6a.dat 32 321 1883 prog6b.dat 34 327 1921 total Assignment: Write a Java program (completely documented according to the class documentation guidelines, of course) that counts lines, words, and bytes (characters) of text files. -

S. Etalle dr. T. Oz¸celebi¨ dr. E. Costante Eindhoven, October 2015 Abstract Maintaining situational awareness in networks of industrial control systems is challenging due to the sheer number of devices involved, complex connections between subnetworks and the delicate nature of industrial processes. While current solutions for automatic discovery of devices and their operating system are lacking, plant operators need to have accurate information about the systems to be able to manage them effectively and detect, prevent and mitigate security and safety incidents. -
