I. INTRODUCTIONIn shell programming, circular commands are used to control the execution of certain statements under certain conditions, and in programming languages, loop statements are one of the most basic syntaxes, and are no exception in the shell. In the shell of the circular statements generally have for, while, until these, and occasionally write the wrong grammar, here combined with examples to summarize their own. It also provides a quick access to information for future use. There are

There are many prevention loop commands in the Cisco environment in addition to spanning trees. The loop generates a broadcast storm that can seriously cause contact blocking, the

This lesson shows how to refactor your old loops into using a simpler and more powerful lodash-style. We'll start by looking at what many people traditionally write JavaScript loops and then talk about the for alternate s Tyle and benefits that Lodash offers.If you want to find one value from the value, you can use:_.findOr_.findlastIf you want to get all match results, you can use:_.filter ()varPeople =[{n

Here is a description of how the nested loops (Nested Loops short nl) are connected. Nested loops, as the name implies is a table as the starting point, the table all records to traverse another table of records, meet the conditions is to write the result set.

The For loop in the bash script, edit bash file 1.sh, enter the following code:
(The code in the example is intended to output numbers from 1 to 10)
Run 1.sh, that is, enter bash 1.sh in the terminal, and the results are as follows:
Execution result Analysis: The first for loop format does not add "" to the following number, makes these numbers not a whole, but the second for loop format adds "" To the following data, which means that the following numbers are consid

Listcomprehension in python is generally used to calculate another list from one list. It is a combination of mapfilter functions and can be implemented cyclically. Some people have said that list derivation is only syntactic sugar, and that list derivation is more efficient than loop and mapfilter (only one test result is given, no relevant analysis), and other valuable information will not be found... this is a question asked by an interviewer. I 'd like to figure it out, so I know that list c
efficiency more efficient than recursion?
Recursion and loop are two different typical solutions. Of course, it doesn't mean that the cycle efficiency must be higher than recursion. recursion and loop are two different things. recursion carries stack operations, while loops are not necessarily. The two concepts are not one level, make different attempts in different scenarios.
