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 + +.... +sort -d /etc/passwd -o /tmp/look.dict +look -t: root:foobar /tmp/look.dict +.... + +== SEE ALSO + +*grep*(1), +*sort*(1) + +include::man-common/bugreports.adoc[] + +include::man-common/footer.adoc[] + +ifdef::translation[] +include::man-common/translation.adoc[] +endif::[] -- cgit v1.2.3
