Gain insights into the power of the command line. Learn about Linux BASH through theoretical and practical exercises, mastering essential concepts and commands for efficient programming.

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"
```
