In economics, an expansion path (also called a scale line [1]) is a path connecting optimal input combinations as the scale of production expands. [2] It is often represented as a curve in a graph with quantities of two inputs, typically physical capital and labor, plotted on the axes. A producer seeking to produce a given number of units of a ...
echo -n in Version 7 replaced prompt, (which behaved like echo but without terminating its output with a line delimiter). [ 17 ] On PWB/UNIX and later Unix System III , echo started expanding C escape sequences such as \n with the notable difference that octal escape sequences were expressed as \0ooo instead of \ooo in C. [ 18 ]
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 ...
Failover: When a path is determined to be in a failed state, a path that is in a ready state will be made active. [10] Failback: When a failed path is determined to be active again, multipathd may choose to failback to the path as determined by the failback policy. [11] Failback Policy: Four options as set in the multipath.conf configuration file.
For example, a "sort" command is unable to produce any output until all input records have been read, as the very last record received just might turn out to be first in sorted order. Dr. Alexia Massalin's experimental operating system, Synthesis , would adjust the priority of each task as they ran according to the fullness of their input and ...
For example, the C shell could not support piping between control structures. Attempting to pipe the output of a foreach command into grep simply didn't work. (The work-around, which works for many of the complaints related to the parser, is to break the code up into separate scripts.
In all Unix and Unix-like systems, as well as on Windows, each process has its own separate set of environment variables.By default, when a process is created, it inherits a duplicate run-time environment of its parent process, except for explicit changes made by the parent when it creates the child.
For example, consider a script having the initial line #! /bin/sh -x. It may be invoked simply by giving its file path, such as some/path/to/foo, [12] and some parameters, such as bar and baz: some/path/to/foo bar baz In this case /bin/sh is invoked in its place, with parameters -x, some/path/to/foo, bar, and baz, as if the original command had ...
