Bash download range of files

Bash provides a lot of useful programming functionalities. We can use for loop for iterative jobs. Linux system administrators generally use for loop to iterate over files and folder. In this tutorial, we will look at how to use for loop to iterate over files and directories in Linux. This mechanism is named as for each some programming languages where a list is iterated over.

Bash provides different usages and syntax for the for loop but in general following syntax is used. One of the most used Numeric syntax. We will provide numbers as a list and iterate over given list. Every number in the list will be iterated inside the for loop one by one. In numeric syntax, it is very similar to the general syntax where we provide a collection of numbers.

We will provide the files as a list and use them in each iteration. In this type, we will iterate over the list of files like file1 , file2 , file3 etc. We can use bash commands output as items for iterate. The simplest usage for for loop is over given file names.

Any idea how to specify echo type sequence via script's parameters? Of course, you'll want to replace '' with the actual number of files, or maybe add some logic to count them beforehand. The input and output strings might need some refinement too, depending on how the "real" URL looks. So, you're looking for something like a little bash utility that would take the URL literal, the output file literal, and the number of files, then run the wget loop based on that info?

You can utilize printf facility in that case. No it doesn't take variables. If you want variable values to be passed in the I need to edit my code. Anyway thanks for your suggestion. What do you mean by user hasn't provided hr, min and sec?

In your script I don't see any min and sec variables. That was a stripped version of my actual script. Sign up or log in Sign up using Google. Sign up using Facebook.
