cut Ref is a lightweight Firefox sidebar extension offering efficient offline access to 107 essential cut command options, field specifications, delimiter patterns, and practical usage scenarios.
The cut command, written by Gottfried W. R. Luderer at Bell Labs in February 1985, originated as a Unix text processing tool for extracting columns and character ranges. It excels at simple column extraction where full regex power isn't required, offering superior performance and simplicity compared to tools like awk for straightforward operations. cut's design embodies the Unix philosophy of creating focused, composable tools.
Content Coverage:
The extension includes essential cut elements:
• Character Operations: Extract specific characters or ranges (-c, -b).
• Field Operations: Select fields, field ranges, and complex field combinations by position with various delimiters (-f, -d).
• Delimiter Support: Commas, tabs, colons, spaces, pipes, and custom characters.
• Output Control: Custom output delimiters and formatted output.
• Line Handling: Suppressing lines without delimiters and complement operations.
• Advanced Features: Complement operations, output delimiter control, line filtering.
• Combination Patterns: Pipelines with grep, sort, awk, and other Unix utilities.
Target Audience:
• System Administrators processing logs and configurations.
• Data Analysts extracting columns from datasets.
• Developers parsing structured text outputs.
• Shell Scripting Enthusiasts building text processing pipelines.
• DevOps Engineers analyzing system outputs.
Use Cases & Practical Applications:
