Origins In the mid 1980s, the two common versions of Unix were BSD , from the University of California, Berkeley , and UNIX System V System V , from AT&T . Both were derived from the earlier Version 7 Unix , but had diverged considerably. Further, each vendor s version of Unix was different to some degree. A group of vendors formed the X Open open standard ..., effectively marking the end of the most significant era of the Unixwars. In June, AT&T sold its UNIX assets to Novell , and in October Novell transferred the Unix brand to X Open. In 1996, X Open and the new OSF merged to form the Open Group . COSE work such as the Single UNIX Specification , the current standard for branded Unix, is now the responsibility of the Open Group. However, the damage to Unix s market reputation had been done.

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.

Unix International or UI was an association created in 1988 to promote open standards, especially the Unix operating system . Its most notable members were AT&T and Sun Microsystems , and in fact the commonly accepted reason for its existence was as a counterbalance to the Open Software Foundation OSF , itself created in response to AT&T s and Sun s Unix partnership of that time. UI and OSF thus represented the two sides of the UnixWars in the late 1980s and early 1990s. In May 1993, the major members of both UI and OSF announced the Common Open Software Environment COSE initiative. This was followed by the merging of UI and OSF into a new OSF in March 1994, which in turn merged with X Open in 1996, forming The Open Group .

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.
