<p><font size=+1><b>DESCRIPTION </b></font><br>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<i>Split</i> reads <i>file</i> (standard input by default) and writes it in
pieces of 1000 lines per output file. The names of the output
files are <tt><font size=+1>xaa</font></tt>, <tt><font size=+1>xab</font></tt>, and so on to <tt><font size=+1>xzz</font></tt>. The options are<br>
<tt><font size=+1>&#8722;n</font></tt> <i>n</i>&nbsp;&nbsp;&nbsp;Split into <i>n</i>-line pieces.<br>
<tt><font size=+1>&#8722;l</font></tt> <i>n</i>&nbsp;&nbsp;&nbsp;Synonym for <tt><font size=+1>&#8722;n</font></tt> <i>n</i>, a nod to Unix&#8217;s syntax.<br>
<tt><font size=+1>&#8722;e</font></tt> <i>expression<br>
</i>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
File divisions occur at each line that matches a regular <i>expression</i>;
see <a href="../man7/regexp.html"><i>regexp</i>(7)</a>. Multiple <tt><font size=+1>&#8722;e</font></tt> options may appear. If a subexpression
of <i>expression</i> is contained in parentheses <tt><font size=+1>(</font></tt>...<tt><font size=+1>)</font></tt>, the output file
name is the portion of the line which matches the subexpression.<br>
</table>
<tt><font size=+1>&#8722;f</font></tt> <i>stem<br>
</i>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
Use <i>stem</i> instead of <tt><font size=+1>x</font></tt> in output file names.<br>
</table>
<tt><font size=+1>&#8722;s</font></tt> <i>suffix<br>
</i>
<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
Append <i>suffix</i> to names identified under <tt><font size=+1>&#8722;e</font></tt>.<br>
</table>
<tt><font size=+1>&#8722;x</font></tt>&nbsp;&nbsp;&nbsp;&nbsp;Exclude the matched input line from the output file.<br>
<tt><font size=+1>&#8722;i</font></tt>&nbsp;&nbsp;&nbsp;&nbsp;Ignore case in option <tt><font size=+1>&#8722;e</font></tt>; force output file names (excluding
the suffix) to lower case.<br>
