features of the Soviet Union ?
ANSWER
Using two standard Unix command-line applications, cat and awk, this bash command executes tasks. Let us examine what each component of the command accomplishes in detail:
The “config.yaml” file’s contents are read and output using the cat command in this section of the command. Concatenate is abbreviated as “cat” and is frequently used to display the contents of text files.
|: This symbol denotes a pipe, and its purpose is to direct the output of the command on its left (cat config. yaml) to the command on its right (awk NF).
Awk NF: The awk utility is used in this command section to perform a specific action, denoted by the expression NF. The term “number of fields” (NF) in the awk programming language evaluates the number of fields (columns) on the input line.
A sophisticated text processing tool that works per line is called awk.
When a pattern to match is not specified (such as /pattern/) before the action, awk will act on each input line.
When there are more fields in a line than zero (i.e. when the line is not empty), the action NF evaluates to true (non-zero).
All told, the command reads the contents of the “config.yaml” file, runs awk on each line, and produces only lines with at least one field (i.e., non-empty lines). This command displays the lines with content while filtering out empty lines from the “config.yaml” file.
