+== NAME
+
+look - display lines beginning with a given string
+
+== SYNOPSIS
+
+*look* [options] _string_ [_file_]
+
+== DESCRIPTION
+
+The *look* utility displays any lines in _file_ which contain _string_ as a prefix. As *look* performs a binary search, the lines in _file_ must be sorted (where *sort*(1) was given the same options *-d* and/or *-f* that *look* is invoked with).
+
+If _file_ is not specified, the file _/usr/share/dict/words_ is used, only alphanumeric characters are compared and the case of alphabetic characters is ignored.
+
+== OPTIONS
+
+*-a*, *--alternative*::
+Use the alternative dictionary file.
+
+*-d*, *--alphanum*::
+Use normal dictionary character set and order, i.e., only blanks and alphanumeric characters are compared. This is on by default if no file is specified.
++
+Note that blanks have been added to dictionary character set for compatibility with *sort -d* command since version 2.28.
+
+*-f*, *--ignore-case*::
+Ignore the case of alphabetic characters. This is on by default if no file is specified.
+
+*-t*, *--terminate* _character_::
+Specify a string termination character, i.e., only the characters in _string_ up to and including the first occurrence of _character_ are compared.
+
+include::man-common/help-version.adoc[]
+
+The *look* utility exits 0 if one or more lines were found and displayed, 1 if no lines were found, and >1 if an error occurred.
+
+== ENVIRONMENT
+
+*WORDLIST*::
+Path to a dictionary file. The environment variable has greater priority than the dictionary path defined in the *FILES* segment.
+
+== FILES
+
+_/usr/share/dict/words_::
+the dictionary
+
+_/usr/share/dict/web2_::
+the alternative dictionary
+
+== HISTORY
+
+The *look* utility appeared in Version 7 AT&T Unix.
+
+== EXAMPLES
+
+....
