I was just wondering what is file globbing? I have never heard of it before and I couldn't find a definition when I tried looking for it online.

p>File globbing also known as Path Name Expansion. It is the method of recognizing wildcard patterns in linux and then finding the file path expansion based on these patterns. Wildcard Patterns are strings that are used for selection of multiple files based on patterns.
Globbing is the process of using wildcard characters to request or evaluate sets of files with the same partial names or sets of characters. Users make the wildcard represent an unknown character or string to search for a wider set of filenames on a particular domain.
The Bash shell feature that is used for matching or expanding specific types of patterns is called globbing. Globbing is mainly used to match filenames or searching for content in a file. Globbing uses wildcard characters to create the pattern.
preventing file globbing The echo * will echo a * when in an empty directory. And it will echo the names of all files when the directory is not empty. Globbing can be prevented using quotes or by escaping the special characters, as shown in this screenshot.
Globbing is the * and ? and some other pattern matchers you may be familiar with.
Globbing interprets the standard wild card characters * and ?, character lists in square brackets, and certain other special characters (such as ^ for negating the sense of a match).
When the shell sees a glob, it will perform pathname expansion and replace the glob with matching filenames when it invokes the program.
For an example of the * operator, say you want to copy all files with a .jpg extension in the current directory to somewhere else:
cp *.jpg /some/other/location Here *.jpg is a glob pattern that matches all files ending in .jpg in the current directory. It's equivalent to (and much easier than) listing the current directory and typing in each file you want manually:
$ ls cat.jpg dog.jpg drawing.png recipes.txt zebra.jpg $ cp cat.jpg dog.jpg zebra.jpg /some/other/location Note that it may look similar, but it is not the same as Regular Expressions.
