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.

A port of Version 6 Unix to the Interdata 7 32 was completed by Richard Miller and Ross Nealon at Wollongong University , Australia , during 1976 1977. This project was supervised by professor Juris Reinfelds . The resulting system was called Wollongong Interdata UNIX, Level 6 . This distribution also included utilities developed at Wollongong, and later releases had features of V7, notably its C programming language C compiler . Wollongong Unix was the first ever port to a platform other than the PDP series of computers, proving that portable operating systems were indeed feasible, and that C was the language in which to write them. In 1980, this version was licensed to The Wollongong Group in Palo Alto that published it as Edition 7.

Unreferenced date December 2009 In Unix 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 source lang bash cut d f 1 etc passwd grep foo source 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 source lang bash perl ne print if m foo etc passwd source Or, to print only the username, without the rest of the line source lang bash perl ane shift F print n if foo F etc passwd source 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.

Administrators can use this to take inventory of the systems and services on their network.

Some examples of tcp and udp port service ports used for banner grabbing are those used by Hyper Text Transfer Protocol HTTP , File Transfer Protocol FTP , and Simple Mail Transfer Protocol SMTP ports 80, 21, and 25 respectively. Tools commonly used to perform banner grabbing are Telnet , which is included with most operating systems , and Netcat .
