| NAME
| split – split a file into pieces
SYNOPSIS
| `split` [ option ... ] [ file ]
DESCRIPTION
| Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file. The names of the output files are `xaa`, `xab`, and so on to `xzz`. The options are `−n` n Split into n-line pieces. `−l` n Synonym for `−n` n, a nod to Unix’s syntax. `−e` expression
| File divisions occur at each line that matches a regular expression; see regexp(7). Multiple `−e` options may appear. If a subexpression of expression is contained in parentheses `(`...`)`, the output file name is the portion of the line which matches the subexpression.
`−f` stem
| Use stem instead of `x` in output file names.
`−s` suffix
| Append suffix to names identified under `−e`.
`−x` Exclude the matched input line from the output file. `−i` Ignore case in option `−e`; force output file names (excluding the suffix) to lower case.
