# Bash User Input
|
|
|
|
With the previous script, we defined a variable, and we output the value of the variable on the screen with the `echo $name`.
|
|
|
|
Now let's go ahead and ask the user for input instead. To do that again, open the file with your favorite text editor and update the script as follows:
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
|
|
echo "What is your name?"
|
|
read name
|
|
|
|
echo "Hi there $name"
|
|
echo "Welcome to DevDojo!"
|
|
```
|
|
|
|
The above will prompt the user for input and then store that input as a string/text in a variable.
|
|
|
|
We can then use the variable and print a message back to them.
|
|
|
|
The output of the above script would be:
|
|
|
|
* First run the script:
|
|
|
|
```bash
|
|
./devdojo.sh
|
|
```
|
|
|
|
* Then, you would be prompted to enter your name:
|
|
|
|
```
|
|
What is your name?
|
|
Bobby
|
|
```
|
|
|
|
* Once you've typed your name, just hit enter, and you will get the following output:
|
|
|
|
```
|
|
Hi there Bobby
|
|
Welcome to DevDojo!
|
|
```
|
|
|
|
To reduce the code, we could change the first `echo` statement with the `read -p`, the `read` command used with `-p` flag will print a message before prompting the user for their input:
|
|
|
|
```bash
|
|
#!/bin/bash
|
|
|
|
read -p "What is your name? " name
|
|
|
|
echo "Hi there $name"
|
|
echo "Welcome to DevDojo!"
|
|
```
|
|
|
|
Make sure to test this out yourself as well! |
