This bash command reads the contents of a file named "config.yaml" using the `cat` command and then pipes (`|`) the output to `awk NF`.
Here's what each part does:
1. `cat config.yaml`: This command prints the contents of the file "config.yaml" to the standard output.
2. `|`: This symbol is the pipe operator, which takes the output of the command on its left and feeds it as input to the command on its right.
3. `awk NF`: This `awk` command is used for text processing. `NF` in `awk` stands for "Number of Fields". When used without a specific pattern, `awk NF` filters out lines that have at least one field (i.e., lines that are not empty or blank). Essentially, it prints only non-empty lines from the input.
So, overall, the command reads the contents of the "config.yaml" file and prints out only the non-empty lines.
