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.
