    The following form allows you to view linux man pages.

    Command:

    look

    
    
    
    

    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) got 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 charac-
         ters is ignored.
    
         Options:
    
         -d      Dictionary character set and order, i.e. only alphanumeric char-
                 acters are compared. (On by default if no file specified).
    
         -f      Ignore the case of alphabetic characters. (On by default if no
                 file specified).
    
         -a      Use the alternate dictionary /usr/share/dict/web2
    
         -t      Specify a string termination character, i.e. only the characters
                 in string up to and including the first occurrence of termchar
                 are compared.
    
         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.
    
    
    

    FILES

         /usr/share/dict/words  the dictionary
         /usr/share/dict/web2   the alternate dictionary

    COMPATIBILITY

         The original manual page stated that tabs and blank characters partici-
         pated in comparisons when the -d option was specified.  This was incor-
         rect and the current man page matches the historic implementation.
    
    
    

    HISTORY

         Look appeared in Version 7 AT&T Unix.
    
    
    

    AVAILABILITY

         The look command is part of the util-linux-ng package and is available
         from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
