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.

lowercase tt yes tt is a Unix command, which outputs an affirmative response, or a user defined string of text continuously until killed. Description By itself, the tt yes tt command outputs y or whatever is specified as an argument, followed by a newline repeatedly until stopped by the user or otherwise Kill Unix killed when piped into a command, it will continue until the pipe breaks i.e., the program completes its execution . It can also be used to test how well a system handles high loads, as using tt yes tt results in 100 processor usage, for systems with a single processor for a multiprocessor system, a process must be run for each processor . This, for example, can be useful for investigating whether a system s cooling system will be effective when the processor is running at 100 . Uses tt yes tt can be used to send an affirmative or negative e.g. tt yes n tt response to any command that would otherwise request one, thereby causing the command to run non interactively. This usage may be obsolete today, as most commands that would request response from the user have either a force option e.g., tt RmUnixrm f tt or an assume yes option e.g., tt Advanced Packaging Tool apt get y tt in Debian . As an example, the following code rm f .txt code is equivalent to code yes rm .txt code The tt yes tt command in conjunction with the Head Unix head command can be used to generate large volume files for means of testing. For example, executing code yes 1234567 head 1000 file code results in a file consisting of 1000 lines each consisting of eight characters 1, 2, 3, 4, 5, 6, 7 and newline .

There are two types of links, both of which are created by tt ln tt symbolic link s, which refer to a symbolic path indicating the abstract location of another file, and hard link s, which refer to the specific location of physical data. These links behave differently when the source of the link what is being linked to is moved or removed. Symbolic links are not updated they merely contain a string which is the pathname of its target hard links always refer to the source, even if moved or removed. Specification The Single Unix Specification SUS specifies the behaviour that a link or links either symbolic or hard will be created where specified that will link to the target file or directory specified. More precisely, tt ln tt can be invoked in one of two ways two arguments first an argument specifying the source file then the target, or multiple greater than two arguments, specifying firstly a number of source files, then a directory in which all the links are to be created.
