Überblick & Funktionsweise
`awk` is a complete programming language designed for data extraction and reporting. It treats text files as tables divided into records (lines) and fields (columns delimited by spaces or commas), making it effortless to parse CSVs, log files, and system process tables.
Wichtige Optionen und Flags
| Flag / Option | Description |
|---|---|
| -F [separator] | Define custom field separator character (e.g., -F: for /etc/passwd). |
| -v [var=val] | Assign a value to an internal awk program variable. |
Praktische Anwendungsbeispiele
awk -F: '{print $1}' /etc/passwdSplits lines by colon (:) and prints the first column containing account usernames.
