| split - split a file into pieces |
SYNOPSIS
| split [ -linecount | -l linecount] [-a suffixlength] [ file [name] ] |
| split [ -b n | nk | nm ] [-a suffixlength] [ file [name] ] |
|
The split utility reads file and writes it in linecount-line pieces into a set of output-files. The name of the first output-file
is name with aa appended, and so on lexicographically, up to zz (a maximum of 676 files). The maximum length of name
is 2 characters less than the maximum filename length allowed by the filesystem. See statvfs(2). If no output name is given, x is used as the default (output-files will be called xaa, xab, and so forth).
|
|
The following options are supported:
-
-linecount | -l linecount
- Number of lines in each piece. Defaults to 1000 lines.
- -a suffixlength
- Uses suffixlength letters to form the suffix portion of the filenames of
the split file. If -a is not specified, the default suffix length is 2. If the sum of the name operand and the suffixlength
option-argument would create a filename exceeding NAME_MAX bytes, an error will result; split will exit with a diagnostic message and no files will be created.
- -b n
- Splits a file into pieces n bytes in size.
- -b nk
- Splits a file into pieces n*1024 bytes in size.
- -b nm
- Splits a file into pieces n*1048576
bytes in size.

The following operands are supported:
-
file
- The path name of the ordinary file to be split. If no input file is given or file is -, the standard input will be used.
-
name
- The prefix to be used for each of the files resulting from the split operation. If no name
argument is given, x will be used as the prefix of the output files. The combined length of the basename of prefix and suffixlength
cannot exceed NAME_MAX bytes; see OPTIONS.

See largefile(5) for the description of the behavior
of split when encountering files greater than or equal to 2 Gbyte ( 231 bytes).

See environ(5) for descriptions of the following environment
variables that affect the execution of split: LC_CTYPE, LC_MESSAGES, and NLSPATH.

The following exit values are returned:
-
0
- Successful completion.
-
>0
- An error occurred.
