In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a heap.
The Unix command clear takes no arguments and is roughly analogous to the command cls on a number of other operating systems. In ISO 9995-7 specifies that the following symbol be used to indicate this function on a keyboard, which is included in Unicode as: ⎚ CLEAR SCREEN SYMBOL. [2] One may use the reset command to erase every previous command.
By default, the command overwrites the file three times with multiple patterns, but the number is user configurable. It has an option to do an additional final overwrite with zeroes, which may help to hide the fact that it was used. By default, shred also shreds file slack (unused space in file allocations). For example, a 5 KB file on a file ...

The command is available in MS-DOS versions 2 (1983) and later. [5] While the ultimate origins of using the three-character string CLS as the command to clear the screen likely predate Microsoft's use, this command was present before its MS-DOS usage, in the embedded ROM BASIC dialects Microsoft wrote for early 8-bit microcomputers (such as TRS-80 Color BASIC), where it served the same purpose.
Useful command lines can be saved by assigning a character string or alias to represent the full command, or several commands can be grouped to perform a more complex sequence – for instance, compile the program, install it, and run it — creating a single entity, called a command procedure or script which itself can be treated as a command ...
rm deletes the file specified after options are added. Users can use a full path or a relative file path to specify the files to delete. rm doesn't delete a directory by default. [13] rm foo deletes the file "foo" in the directory the user is currently in. rm, like other commands, uses options to specify how it will behave:
