Others (such as many Unix media players) may read files from standard input. Popular Windows programs that open a separate console window in addition to their GUI windows are the emulators pSX and DOSBox. GTK-server can use stdin as a communication interface with an interpreted program to realize a GUI.
Alternatively, if the drain does not need to read any input from stdin to do something useful, it can be given < /dev/null as input. As all components of a pipe are run in parallel, a shell typically forks a subprocess (a subshell) to handle its contents, making it impossible to propagate variable changes to the outside shell environment.
File descriptors for a single process, file table and inode table. Note that multiple file descriptors can refer to the same file table entry (e.g., as a result of the dup system call [3]: 104 ) and that multiple file table entries can in turn refer to the same inode (if it has been opened multiple times; the table is still simplified because it represents inodes by file names, even though an ...
sudo is unable to pipe the standard output to a file. By dumping its stdout stream into /dev/null , we also suppress the mirrored output in the console. The command above gives the current user root access to a server over ssh, by installing the user's public key to the server's key authorization list.

To be effectively implemented, data pipelines need a CPU scheduling strategy to dispatch work to the available CPU cores, and the usage of data structures on which the pipeline stages will operate on. For example, UNIX derivatives may pipeline commands connecting various processes' standard IO, using the pipes implemented by the operating system.
Alternatively, you can use 2 cups of chicken or turkey broth. Melt the butter in a small saucepan set over medium-low heat. Once melted, add the flour and whisk until the roux reaches a smooth ...
