NAME
split —
split a file into pieces
SYNOPSIS
split |
-d [ -l line_count][ -a suffix_length][ file [ prefix]] |
split |
-d -b byte_count[ K| k| M| m| G| g][ -a suffix_length][ file [ prefix]] |
split |
-d -n chunk_count [ -a suffix_length][ file [ prefix]] |
split |
-d -p pattern [ -a suffix_length][ file [ prefix]] |
DESCRIPTION
The
split utility reads the given
file and breaks it up into files of 1000 lines each (if no options are specified), leaving the
file unchanged. If
file is a single dash (‘
-’) or absent,
split reads from the standard input.
The options are as follows:
-
-a
suffix_length
-
Use
suffix_length letters to form the suffix of the file name.
-
-b
byte_count[
K| k| M| m| G| g]
-
Create split files
byte_count bytes in length. If
k or
K is appended to the number, the file is split into
byte_count kilobyte pieces. If
m or
M is appended to the number, the file is split into
byte_count megabyte pieces. If
g or
G is appended to the number, the file is split into
byte_count gigabyte pieces.
-
-d
-
Use a numeric suffix instead of a alphabetic suffix.
-
-l
line_count
-
Create split files
line_count lines in length.
-
-n
chunk_count
-
Split file into
chunk_count smaller files.
-
-p
pattern
-
The file is split whenever an input line matches
pattern, which is interpreted as an extended regular expression. The matching line will be the first line of the next output file. This option is incompatible with the
-b and
-l options.
If additional arguments are specified, the first is used as the name of the input file which is to be split. If a second additional argument is specified, it is used as a prefix for the names of the files into which the file is split. In this case, each file into which the file is split is named by the prefix followed by a lexically ordered suffix using suffix_length characters in the range “ a
- z
”. If -a is not specified, two letters are used as the suffix.
If the prefix argument is not specified, the file is split into lexically ordered files named with the prefix “ x
” and with suffixes as above.
ENVIRONMENT
The
LANG,
LC_ALL,
LC_CTYPE and
LC_COLLATE environment variables affect the execution of
split as described in
environ(7).
EXIT STATUS
The
split utility exits 0 on success, and >0 if an error occurs.
STANDARDS
The
split utility conforms to IEEE Std 1003.1-2001 (“POSIX.1”).
HISTORY
A
split command appeared in Version 3 AT&T UNIX.
BUGS
The maximum line length for matching patterns is 65536.
