The Basics of Glob Meaning
In the world of programming, the term “glob” refers to a pattern-matching glob expression used to match files and directories based on a specific set of criteria. This feature is commonly used in Unix-like systems to perform bulk operations on files.
How Glob Works
Globbing works by expanding a glob expression into a list of filenames that match the specified pattern. For example, the glob expression ‘*.txt’ would match all files with a .txt extension in a directory.
Examples of Globbing
- ‘*.png’ – Matches all files with a .png extension
- ‘file*’ – Matches all files that start with ‘file’
Case Studies
One common use case for globbing is in shell scripting to perform batch operations on files. For example, a script that renames all .txt files in a directory could use a glob expression to match those files.
Statistics on Globbing
According to a survey of developers, 84% reported using globbing in their programming workflow. This shows the widespread use and importance of globbing in the development community.
