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. A sample command to compile a C programming language C program at 11 45 a. m. on January 31st and e mail the results Standard streams STDOUT and STDERR to your user ID would be source lang bash echo cc o foo foo.c at 1145 at 1145 jan 31 at cc o foo foo.c at D press Control D while at the beginning of a line atq 1234 2011 08 12 11 45 cc o foo foo.c user atrm 1234 atq source In some Unix like computer operating system s it uses a Daemon computer software daemon , code atd code , which waits in the background periodically checking ....

lowercase head is a Computer program program on Unix and Unix like systems used to display the first few lines of a text Computer file file or pipe computing pipe d data. The command syntax is head options < file name> By default, tt head tt will print the first 10 lines of its input to the standard output . The number of lines printed may be changed with a command line option. The following example shows the first 20 lines of filename head n 20 filename This displays the first 5 lines of all files starting with foo head n 5 foo Some versions omit the n and just let you say 5. Flags c x number of bytes Copy first x number of bytes.

The program reads either standard input or a list of files and generates one or more of the following statistics number of bytes, word count number of words , and number of lines specifically, the number of newline characters . If a list of files is provided, both individual file and total statistics follow. Sample execution of tt wc tt wc foo bar 40 149 947 foo 2294 16638 97724 bar 2334 16787 98671 total The first column is the count of newlines, meaning that the text file tt foo tt has 40 newlines while tt bar tt has 2294 newlines resulting in a total of 2334 newlines. The second column indicates the number of words in each text file showing that there are 149 words in tt foo tt and 16638 words in tt bar tt giving a total of 16787 words. The last column indicates the number of characters in each text file, meaning that the file tt foo tt has 947 characters while tt bar tt has 97724 characters 98671 characters all in all. Newer versions of tt wc tt can differentiate between byte and character computing character count. This difference arises with Unicode which includes multi byte characters.

When executed, the program reads from the standard input and writes to the standard output. It takes as Command line argument parameters two sets of characters, and replaces occurrences of the characters in the first set with the corresponding elements from the other set. For example, source lang bash tr abcd jkmn source maps a to j , b to k , c to m , and d to n . Sets of characters may be abbreviated by using character ranges. The previous example could be written source lang bash tr a d jkmn source In POSIX compliant versions of tr the set represented by a character range depends on the locale s collating order, so it is safer to avoid character ranges in scripts that might be executed in a locale different from that in which they were written. Ranges can often be replaced with POSIX character sets such as alpha . The c flag complements the first set of characters. source lang bash tr cd alnum source therefore removes all non alphanumeric characters.
