The pcregrep command is an implementation of grep that uses Perl regular expression syntax. [17] Similar functionality can be invoked in the GNU version of grep with the -P flag. [18] Ports of grep (within Cygwin and GnuWin32, for example) also run under Microsoft Windows. Some versions of Windows feature the similar qgrep or findstr command. [19]
He later added this capability to the Unix editor ed, which eventually led to the popular search tool grep's use of regular expressions ("grep" is a word derived from the command for regular expression searching in the ed editor: g/re/p meaning "Global search for Regular Expression and Print matching lines").

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.

Installation (or setup) of a computer program (including device drivers and plugins), is the act of making the program ready for execution. Installation refers to the particular configuration of software or hardware with a view to making it usable with the computer. A soft or digital copy of the piece of software (program) is needed to install it.
First appearing in Version 7 Unix, [3] sed is one of the early Unix commands built for command line processing of data files. It evolved as the natural successor to the popular grep command. [4] The original motivation was an analogue of grep (g/re/p) for substitution, hence "g/re/s". [3]
Setup begins to expand Windows files using a WIM image (aka install.wim). If the user has picked to upgrade from a current install of Windows (e.g. Windows 7 to 10), the files and applications will be transferred. If booting from the installation disk, the bootloader is installed (in the case of Windows Vista and above, this would be BOOTMGR).
