# csplit
> Split a file into pieces.
> This generates files named "xx00", "xx01", and so on.
- Split a file at lines 5 and 23:
`csplit {{file}} {{5}} {{23}}`
- Split a file every 5 lines (this will fail if the total number of lines is not divisible by 5):
`csplit {{file}} {{5}} {*}`
- Split a file every 5 lines, ignoring exact-division error:
`csplit -k {{file}} {{5}} {*}`
- Split a file at line 5 and use a custom prefix for the output files:
`csplit {{file}} {{5}} -f {{prefix}}`
- Split a file at a line matching a regular expression:
`csplit {{file}} /{{regex}}/`
