If pushd is not provided with a path argument, in Unix it instead swaps the top two directories on the stack, which can be used to toggle between two directories. The popd command removes (or 'pops', in the stack analogy) the current path entry from the stack and returns to the path at the top of the stack as the new working directory. [4] [5]
"Zero-copy" describes computer operations in which the CPU does not perform the task of copying data from one memory area to another or in which unnecessary data copies are avoided. This is frequently used to save CPU cycles and memory bandwidth in many time consuming tasks, such as when transmitting a file at high speed over a network, etc., thus improving the performance of programs executed by
copy letter.txt [destination] Files may be copied to device files (e.g. copy letter.txt lpt1 sends the file to the printer on lpt1. copy letter.txt con would output to stdout, like the type command. Note that copy page1.txt+page2.txt book.txt will concatenate the files and output them as book.txt. Which is just like the cat command). It can ...
cpio is a general file archiver utility and its associated file format.It is primarily installed on Unix-like computer operating systems. The software utility was originally intended as a tape archiving program as part of the Programmer's Workbench (), and has been a component of virtually every Unix operating system released thereafter.
Creating a copy of a file in the current directory: cp prog.c prog.bak This copies prog.c to prog.bak. If the prog.bak file does not already exist, the cp command creates it. If it does exist, the cp command replaces its contents with the contents of the prog.c file. Copy two files in the current directory into another directory:
scrcpy (short for "screen copy") is a free and open-source screen mirroring application that allows control of an Android device from a desktop computer. [2] The software is developed by Genymobile SAS, a company which develops Android emulator Genymotion. [3] The application primarily uses the Android Debug Bridge (ADB) via a USB connection to ...
Secure copy protocol (SCP) is a means of securely transferring computer files between a local host and a remote host or between two remote hosts. It is based on the Secure Shell (SSH) protocol. [1] "SCP" commonly refers to both the Secure Copy Protocol and the program itself. [2]
It is sometimes called the current working directory (CWD), e.g. the BSD getcwd [1] function, or just current directory. [2] When a process refers to a file using a path that does not begin with a / (forward slash), the path is interpreted as relative to the process's working directory.
