In Unix-like operating systems, find is a command-line utility that locates files based on some user-specified criteria and either prints the pathname of each matched object or, if another action is requested, performs that action on each matched object.
In the above example, the find utility feeds the input of xargs with a long list of file names. xargs then splits this list into sublists and calls rm once for every sublist. Some implementations of xargs can also be used to parallelize operations with the -P maxprocs argument to specify how many parallel processes should be used to execute the ...
For example, in Python, to print the string Hello, World! followed by a newline, one only needs to write print ("Hello, World!" In contrast, the equivalent code in C++ [ 7 ] requires the import of the input/output (I/O) software library , the manual declaration of an entry point , and the explicit instruction that the output string should be ...

A system call is an entry point into the Linux kernel. [202] For example, among the Linux-specific ones there is the family of the clone(2) system calls. [203] Most extensions must be enabled by defining the _GNU_SOURCE macro in a header file or when the user-land code is being compiled. [204]

Although the ncurses library was initially developed under Linux, OpenBSD, FreeBSD, and NetBSD, it has been ported to many other ANSI/POSIX UNIX systems, mainly by Thomas Dickey. PDCurses, while not identical to ncurses, uses the same function calls and operates the same way as ncurses does except that PDCurses targets different devices, e.g ...
