The pushd ('push directory') command saves the current working directory to the stack then changes the working directory to the new path input by the user. 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.
Some versions of Unix and Linux contain Bash system startup scripts, generally under the /etc directory. Bash executes these files as part of its standard initialization, but other startup files can read them in a different order than the documented Bash startup sequence.
For example, to implement a network address translation (NAT) server, a union directory can be created, overlaying the router's /net directory tree with its own /net. Similarly, a virtual private network (VPN) can be implemented by overlaying in a union directory a /net hierarchy from a remote gateway , using secured 9P over the public Internet.
In OS/2 version 1.2 and later, the High Performance File System was designed with extended attributes in mind, but support for them was also retro-fitted on the FAT filesystem of DOS. For compatibility with other operating systems using a FAT partition, OS/2 attributes are stored inside a single file "EA DATA. SF" located in the root directory ...

[ 20 ] [ 19 ] See also the similar environment variable %DIRCMD% and the DIR options /C and /R of the DR-DOS COMMAND.COM.

The init system is the first daemon to start (during booting) and the last daemon to terminate (during shutdown). Systemd load is a runlevel target to ...
Loadable kernel modules in Linux are loaded (and unloaded) by the modprobe command. They are located in /lib/modules or /usr/lib/modules and have had the extension .ko ("kernel object") since version 2.6 (previous versions used the .o extension). [5] The lsmod command lists the loaded kernel modules.
