|
|
|
|
> Split a file into pieces.
|
|
> This generates files named `xx00`, `xx01`, and so on.

|
|
|
|
- Split a file in two parts, starting the second one at line 10:
|
|
|
|
`csplit {{path/to/file}} 10`
|
|
|
|
- Split a file in three parts, starting the latter parts in lines 7 and 23:
|
|
|
|
`csplit {{path/to/file}} 7 23`
|
|
|
|
- Start a new part at every 5th line (will fail if number of lines is not divisible by 5):
|
|
|
|
`csplit {{path/to/file}} 5 {*}`
|
|
|
|
- Start a new part at every 5th line, ignoring exact-division error:
|
|
|
|
`csplit {{[-k|--keep-files]}} {{path/to/file}} 5 {*}`
|
|
|
|
- Split a file above line 5 and use a custom prefix for the output files (default is `xx`):
|
|
|
|
`csplit {{path/to/file}} 5 {{[-f|--prefix]}} {{prefix}}`
|
|
|
|
- Split a file above the first line matching a `regex` pattern:
|
|
|
|
`csplit {{path/to/file}} /{{regex}}/`
