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.
Changes file group ownership chown: Changes file ownership chmod: Changes the permissions of a file or directory cp: Copies a file or directory dd: Copies and converts a file df: Shows disk free space on file systems dir: Is exactly like "ls -C -b".

Support for command history means that a user can recall a previous command into the command-line editor and edit it before issuing the potentially modified command. Shells that support completion may also be able to directly complete the command from the command history given a partial/initial part of the previous command.
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.
In benchmarks, WSL 1's performance is often near native Linux Ubuntu, Debian, Intel Clear Linux or other Linux distributions. I/O is in some tests a bottleneck for WSL. [47] [48] [49] The redesigned WSL 2 backend is claimed by Microsoft to offer twenty-fold increases in speed on certain operations compared to that of WSL 1. [7]
xargs (short for "extended arguments") [1] is a command on Unix and most Unix-like operating systems used to build and execute commands from standard input. It converts input from standard input into arguments to a command. Some commands such as grep and awk can take input either as
chroot — Run command within a new root directory. chrt; chvt; cksum — For each file, output crc32 checksum value, length and name of file. clear — Clear the screen. cmp — Compare the contents of two files. comm — Select or reject lines common to two files. cp — Copy files. cpio — Copy files into and out of a "newc" format cpio ...
The IDE makes it easy to select components and place them on a form, editing properties and event handlers with an "Object Inspector". Delphi's VCL is an object-oriented wrapper over raw Win32 controls, that maps Win32 messages and APIs to properties and events and is thus significantly easier to use than the raw API.
