<table border=0 cellpadding=0 cellspacing=0><tr height=2><td><tr><td width=20><td>
<tt><font size=+1>look</font></tt> [ <tt><font size=+1>−dfnixt</font></tt><i>c</i> ] [ <i>string</i> ] [ <i>file</i> ]<br>

<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>Look</i> consults a sorted <i>file</i> and prints all lines that begin with
<i>string</i>. It uses binary search.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
The following options are recognized. Options <tt><font size=+1>dfnt</font></tt> affect comparisons
as in <a href="../man1/sort.html"><i>sort</i>(1)</a>.<br>
<tt><font size=+1>−i</font></tt> Interactive. There is no <i>string</i> argument; instead <i>look</i> takes
lines from the standard input as strings to be looked up.<br>
<tt><font size=+1>−x</font></tt> Exact. Print only lines of the file whose key matches <i>string</i>
exactly.<br>
<tt><font size=+1>−d</font></tt> ‘Directory’ order: only letters, digits, tabs and blanks participate
in comparisons.<br>
<tt><font size=+1>−f</font></tt> Fold. Upper case letters compare equal to lower case.<br>
<tt><font size=+1>−n</font></tt> Numeric comparison with initial string of digits, optional minus
sign, and optional decimal point.<br>
<tt><font size=+1>−t</font></tt>[<i>c</i>]Character <i>c</i> terminates the sort key in the <i>file</i>. By default,
tab terminates the key. If <i>c</i> is missing the entire line comprises
the key.
<table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table>
If no <i>file</i> is specified, <tt><font size=+1>/lib/words</font></tt> is assumed, with collating
sequence <tt><font size=+1>df</font></tt>.<br>

The exit status is “<tt><font size=+1>not found</font></tt>” if no match is found, and “<tt><font size=+1>no dictionary</font></tt>”
if <i>file</i> or the default dictionary cannot be opened.<br>
