The first operation may be performed by programs such as losetup [8] in Linux, or lofiadm [9] in SunOS. As an example, if example.img is a regular file containing a file system and /home/you/dir is a Linux user's directory, the superuser (root) may mount the file on the directory by executing the following two commands:
Utilities listed in POSIX.1-2017. This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS).
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]
Boot messages of a Linux kernel 2.6.25.17. The basic components of the Linux family of operating systems, which are based on the Linux kernel, the GNU C Library, BusyBox or forks thereof like μClinux and uClibc, have been programmed with a certain level of abstraction in mind.
In addition, the 'usual and customary' programming languages installed with a Linux distribution, including C, C++, Python, PHP, Perl, Tcl/Tk, and Lua are available, along with multiple development libraries. In addition to Bash, the GNU Utilities (e.g. find utilities, such as locate, find, grep) are installed by default.
epoll is a Linux kernel system call for a scalable I/O event notification mechanism, first introduced in version 2.5.45 of the Linux kernel. [1] Its function is to monitor multiple file descriptors to see whether I/O is possible on any of them.
sed ("stream editor") is a Unix utility that parses and transforms text, using a simple, compact programming language. It was developed from 1973 to 1974 by Lee E. McMahon of Bell Labs, [1] and is available today for most operating systems.
Modular operating systems such as OS-9 and most modern monolithic-kernel operating systems such as OpenVMS, Linux, FreeBSD, NetBSD, DragonFly BSD, Solaris, and AIX can dynamically load (and unload) executable kernel modules at runtime. This modularity of the operating system is at the binary (image) level and not at the architecture level.
