split - split a file into pieces
split [-linecount | -l linecount] [-a suffixlength] [file [name]]
split [-b n] [-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). 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:
Number of lines in each piece. Defaults to 1000 lines.
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.
Splits a file into pieces n bytes in size. The value n is a plain number, with an optional fraction and scale factor representing multiples of 1024 bytes: k, m, g, t, p, or e, denoting kilobytes, megabytes, gigabytes, terabytes, petabytes, or exabytes respectively.
Print usage message and immediately exit.
The following operands are supported:
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.
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.
See environ(7) for descriptions of the following environment variables that affect the execution of split: LANG, LC_ALL , LC_CTYPE, LC_MESSAGES, and NLSPATH.
The following exit values are returned:
An error occurred.
