Drinking sugary drinks daily leads to obesity. A complex hypothesis examines the relationship between two or more independent variables and two or more dependent variables. Overweight adults who 1 value longevity and 2 seek happiness are more likely than other adults to 1 lose their excess weight and 2 feel a more regular sense of joy. A null hypothesis H0 exists when a researcher believes there is no relationship between the two variables, or there is a lack of information to state a scientific hypothesis.
Expressions may be combined using the following operators, listed in decreasing order of precedence: This may be used to override the normal precedence of operators. Conditional ConstructsUp: When commands are grouped, redirections may be applied to the entire command list. For example, the output of all the commands in the list may be redirected to a single stream.
Since the list is executed in a subshell, variable assignments do not remain in effect after the subshell completes. No subshell is created. The semicolon or newline following list is required. In addition to the creation of a subshell, there is a subtle difference between these two constructs due to historical reasons.
The braces are reserved words, so they must be separated from the list by blanks or other shell metacharacters.
The parentheses are operators, and are recognized as separate tokens by the shell even if they are not separated from the list by whitespace. The exit status of both of these constructs is the exit status of list. GNU ParallelPrevious: Compound CommandsUp: The format for a coprocess is: NAME must not be supplied if command is a simple command see Simple Commands ; otherwise, it is interpreted as the first word of the simple command.
When the coprocess is executed, the shell creates an array variable see Arrays named NAME in the context of the executing shell. The standard output of command is connected via a pipe to a file descriptor in the executing shell, and that file descriptor is assigned to NAME.
The standard input of command is connected via a pipe to a file descriptor in the executing shell, and that file descriptor is assigned to NAME. This pipe is established before any redirections specified by the command see Redirections.
The file descriptors can be utilized as arguments to shell commands and redirections using standard word expansions. The file descriptors are not available in subshells. The wait builtin command may be used to wait for the coprocess to terminate.
Since the coprocess is created as an asynchronous command, the coproc command always returns success. The return status of a coprocess is the exit status of command.
GNU Parallel is a tool to do just that.
GNU Parallel, as its name suggests, can be used to build and run commands in parallel. You may run the same command with different arguments, whether they are filenames, usernames, hostnames, or lines read from files. GNU Parallel provides shorthand references to many of the most common operations input lines, various portions of the input line, different ways to specify the input source, and so on.
Parallel can replace xargs or feed commands from its input sources to several different instances of Bash. For a complete description, refer to the GNU Parallel documentation.
A few examples should provide a brief introduction to its use. For example, it is easy to replace xargs to gzip all html files in the current directory and its subdirectories: You can use Parallel to move files from the current directory when the number of files is too large to process with one mv invocation:WHAT IS AN ANNOTATED BIBLIOGRAPHY?
An annotated bibliography is a list of citations to books, articles, and documents. Each citation is followed by a brief (usually about words) descriptive and evaluative paragraph, the annotation.
