Ever wondered why command line is still in use even when there are hundreds of human-friendly GUI’s and tools available? Everyone in the programmer's world would agree on one thing: Command Line is far more powerful than any GUI. It provides a richer experience in terms of speed and expressiveness.

For beginners, it might be hard to appreciate its beauty and a little challenging to shift from an interactive interface to a blank box with just a “$” sign showing that keeps prompting the user to enter complex commands if you want to get something done. This is why we felt the need to build a course which could help the user overcome his/her fear of using the terminal (we have all been there).

The objective of this course is to help you get a strong grip over Linux, mainly focusing on BASH. You will be covering both, the theoretical and practical sides. First, you will learn a bunch of concepts necessary to understand things and then study some nifty commands to get useful things done out of them.

Bash for Programmers

# locate 
### Definition:
The command `locate` is a quick way to search for the locations of files and directories.
### Syntax:
```shell
locate [options] name(s)
```
### Options:
|**Option**|**Description**|
| --- | --- |
| -q | To suppress error messages, such as those that might be returned in the event that the user does not have permission to access designated files or directories. |
| -n | This option followed by an integer limits the results to a specific number. |
| -i | To perform a case-insensitive search. |
| -V | To show which version of locate is used, including whether it is locate or slocate. |
### Example:
- To search for all files named 'file1' and all directories named 'dir1', for which the user had access permission:
```shell
locate file1 dir1
```
- To display all the files in the system with **".jpeg"** extension:
```shell
locate "*.jpeg"
```
- In the above example, in order to display only **10** results:
```shell
locate -n 10 "*.jpeg"
```
