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.

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 , SortUnixsort , uniq and tail Unix tail .

The basic idea is to eliminate turtles , or small values near the end of the list, since in a bubble sort these slow ... a problem in bubble sort. . In bubble sort, when any two elements are compared, they always have a gap distance from each other of 1. The basic idea of comb sort is that the gap can be much more than one. Shell sort is also based on this idea, but it is a modification of insertion sort rather than bubble sort. The gap starts out as the length of the list being sorted divided by the shrink factor generally ..., and the process repeats until the gap is 1. At this point, comb sort continues using a gap of 1 until the list is fully sorted. The final stage of the sort is thus equivalent to a bubble sort, but by this time most turtles have been dealt with, so a bubble sort will be efficient.

This is possible because the key for a bead sort is always a positive integer and bead sort exploits its structure ... publications journals beadsort.pdf The Bead Sort paper 114 Kibibyte KiB application pdf, 117730 bytes http mgs.spatial computing.org ImageGallery EXEMPLES BeadSort index.html Bead Sort in MGS , a visualization of a bead sort implemented in the http mgs.spatial computing.org MGS programming language http mathworld.wolfram.com Bead Sort.html Bead Sort on MathWorld sorting Category Sorting algorithms ... more details
list. In a Sorting algorithm Stability stable sort , the input order determines the sorted order ... or if they weigh the same . Examples File Bubble sort animation.gif thumb right 250px A bubble sort, a sorting algorithm that continuously steps through a list, Swap computer science swapping items ... sort Heap sort Merge sort Intro sort Insertion sort Selection sort Bubble sort Odd even sort Cocktail sort Cycle sort Merge insertion Ford Johnson sort Smoothsort Timsort There are many integer sorting algorithms that are not comparison sorts they include Radix sort examines individual bits of keys Counting sort indexes using key values Bucket sort examines bits of keys Performance limits and advantages ... sorts. A comparison sort must have a lower bound of big O notation n log n comparison operations ... to be sorted in reverse for instance, one can sort a list of tuple s in lexicographic order by just .... Additionally, once a comparison function is written, any comparison sort can be used without ... required to sort a list The number of comparisons that a comparison sort algorithm requires increases at least in proportion to math n log n math , where math n math is the number of elements to sort ... of which is the list in sorted order. The sort algorithm must gain enough information from the comparisons ... tolerance by a simple merge sort , but it is known to be inexact. For example, math lceil log 2 13 rceil 33 math , but the minimal number of comparisons to sort 13 elements has been proved to be 34 ref ... ref . Determining the exact number of comparisons needed to sort a given number of entries is a computationally ... k bits on average. To perform the sort, complete information is needed, so the remaining entropy ... bounds for sorting, pp. 165&ndash 168. DEFAULTSORT Comparison Sort Category Sorting algorithms ... more details
list. The difference between pigeonhole sort and counting sort is that in counting sort, the auxiliary ... only once. Pigeonhole sort, in contrast, moves items twice once onto the pigeonhole bucket array ... pigeonholeSort.html first Paul E. last Black title pigeonhole sort , in Dictionary of Algorithms and Data ... accessdate 2009 04 26 ref For arrays where N is much larger than n , bucket sort is a generalization that is more efficient in space and time.
