Split a file based on the context (POSIX)
csplit [-ks] [-f prefix] [-n digits] file arg1 [... argn]
- -f prefix
- Use prefix instead of xx to name the output files
(i.e. name the created files prefix00, prefix01,
..., prefixn instead of xx00, ...,
- Leave previously created files intact.
By default, csplit removes created files if an error occurs.
- -n digits
- The number of digits to append to the prefix.
The default is 2.
- Suppress the output of file size messages.
The csplit utility splits a file into n + 1 sections,
as prescribed by arg1...argn, and then displays the
size of the output files.
Each argument specifies where a section ends as follows:
- Copy lines until the next line matches the regular expression,
A positive or negative relno specifies a relative line number
from the match.
- Same as above, except the lines are discarded instead.
- Copy nlines lines from the file.
- Repeat the preceding argument this number of times.
Extract a file that's encoded with
csplit mail '%^begin%' '/^end/+1' '%.*%'
Split a file into three parts of 1, 10, and 100 lines:
csplit file 1 10 100
- An error occurred.
