# Make it executable: | ||
|
||
- In the terminal, navigate to the directory where you saved your script. | ||
- Run the command `chmod +x generate_password.sh` This command adds execute permissions to the script. | ||
|
||
# Run it with the desired password length as an argument: | ||
|
||
- After making the script executable, you can run it by providing the desired password length as a command-line argument. | ||
- Use the following syntax: `./generate_password.sh <password_length>` , replacing `<password_length>` with the actual length you want. | ||
|
||
Here's an example: | ||
|
||
```shell | ||
./generate_password.sh 12 | ||
``` | ||
|
||
This will execute the script (**generate_password.sh**) with a password length of **12** , and the script will generate and print a random password of that length. Adjust the length as needed based on your requirements. |

Hi @alirafatartist, The CI job is failing:
Can we make the default value of
length
to be 8 if there is no input so it can be run on the CI job as well?Something like:
local length=${1:-8}
