- Concatenate specific files in reversed order:
|
|
|
|
`tac {{path/to/file1 path/to/file2 ...}}`
|
|
|
|
- Display `stdin` in reversed order:
|
|
|
|
`{{cat path/to/file}} | tac`
|
|
|
|
- Use a specific separator:
|
|
|
|
`tac {{[-s|--separator]}} {{separator}} {{path/to/file1 path/to/file2 ...}}`
|
|
|
|
- Use a specific regex as a separator:
|
|
|
|
`tac {{[-r|--regex]}} {{[-s|--separator]}} {{separator}} {{path/to/file1 path/to/file2 ...}}`
|
|
|
|
- Use a separator before each file:
|
|
|
|
`tac {{[-b|--before]}} {{path/to/file1 path/to/file2 ...}}`
