- Number non-blank lines in a file:
|
|
|
|
`nl {{path/to/file}}`
|
|
|
|
- Read from `stdin`:
|
|
|
|
`{{command}} | nl -`
|
|
|
|
- Number [a]ll [b]ody lines including blank lines or do not [n]umber [b]ody lines:
|
|
|
|
`nl --body-numbering {{a|n}} {{path/to/file}}`
|
|
|
|
- Number only the [b]ody lines that match a basic regular expression (BRE) [p]attern:
|
|
|
|
`nl --body-numbering p'FooBar[0-9]' {{path/to/file}}`
|
|
|
|
- Use a specific [i]ncrement for line numbering:
|
|
|
|
`nl --line-increment {{increment}} {{path/to/file}}`
|
|
|
|
- Specify the line numbering format to [r]ight or [l]eft justified, keeping leading [z]eros or [n]ot:

`nl --number-format {{rz|ln|rn}}`
|
|

- Specify the line numbering's width (6 by default):
|
|
|
|
`nl --number-width {{col_width}} {{path/to/file}}`
|
|
|
|
- Use a specific string to separate the line numbers from the lines (TAB by default):
|
|
|
|
`nl --number-separator {{separator}} {{path/to/file}}`
