Other uses AT disambiguation lowercase In Unix like computer operating system s, the code at code command is used to schedule command computing command s to be executed once, at a particular system time time in the future. More precisely, it reads a series of commands from standard input and collects them into one at job which is carried out at a later date. The at job inherits the current environment, so that it is executed in the same working directory and with the same environment variable s set as when it was scheduled. It differs from code cron code which is used for recurring executions e.g. once an hour, every Tuesday, January 1 every year . As with code cron code , many Unix systems allow the administrator to restrict access to the code at code command. code at code can be made to mail a user when done carrying out a scheduled job of theirs, can use more than one job queue, and can read a list of jobs to carry out from a file instead of standard input.

Bell Unix PWB UNIX for Programmer s Workbench was an early version of the Unix operating system . Prior to 1976 Unix development at AT&T was done by a small group of researchers in the Bell Labs Computer Science Research Group Department 1127 . But as word of the usefulness of Unix spread throughout the company the decision was made to develop a version of Unix tailored to support programmer s doing production work, not research. The Programmer s Workbench was started in 1973 ref name Mashey John R. Mashey 2004 . http queue.acm.org detail.cfm?id 1039532 Languages, Levels, Libraries, and Longevity . ACM Queue 2 9 . ref by Evan Ivie and Rudd Canaday to support a computer center for a 1000 employee Bell Labs division, which would be the largest Unix site for several years to come. PWB UNIX was to provide tools for teams of programmers to manage their source code and collaborate on projects with other team members. While the PWB group managed their source on Unix systems, programs were often written to run on other legacy operating systems. For this reason, PWB included software for Batch processing submitting jobs to IBM System 370 , UNIVAC 1100 series, and XDS SDS Sigma 5 Sigma 5 computers. In 1978 it was documented that PWB supported a user community of about 1,100 users in the Business Information Systems Programs BISP group in Bell Labs. There were two major releases of Programmer s Workbench. PWB UNIX 1.0, released July 1, 1977 was based on Version 6 Unix PWB 2.0 was based on Version 7 Unix .

Unreferenced date December 2009 Mergeto filter software date November 2008 In UnixUNIX and UNIX like operating systems, a filter is a program that gets most of its data from its standard input the main input stream and writes its main results to its standard output the main output stream . UNIX filters are often used as elements of pipeline Unix pipeline s. The pipe operator on a command line signifies that the main output of the command to the left is passed as main input to the command on the right. The classic filter would be grep , which at it simplest prints to its output any lines containing a character string. Here s an example cut d f 1 etc passwd grep foo This finds all registered users that have foo as part of their username by using the Cut Unix cut command to take the first field username of each line of the UNIX system password file and passing them all as input to grep, which searches its input for lines containing the character string foo and prints them on its output. Here is a perl equivalent to the above, which prints the whole line from the passwd file perl ne print if m foo etc passwd Or, to print only the username, without the rest of the line perl ane shift F print n if foo F etc passwd Common UNIX filter programs are Cat Unix cat , cut Unix cut , grep , head Unix head , Sort Unix sort , uniq and tail Unix tail . Programs like awk and sed can be used to build quite complex filters because they are fully programmable.

Bell Unix Columbus UNIX or CB UNIX was, according to Marc Rochkind ref cite book last Rochkind first Marc title Advanced UNIX Programming publisher Prentice Hall year 1985 pages 156 157 isbn 0 13 011800 1 ref , a variant of the UNIX operating system internal to Bell Labs . It was developed at the Columbus, Ohio Columbus , Ohio branch and was little known outside the company. CB UNIX was developed to address deficiencies inherent in Research Unix , notably the lack of interprocess communication and file locking , considered essential for a database management system . Several Bell System operation support system products were based on CB UNIX such as Switching Control Center System .
