NAME    [Toc]    [Back]

     look -- display lines beginning with a given string

SYNOPSIS    [Toc]    [Back]

     look [-df] [-t termchar] string [file ...]

DESCRIPTION    [Toc]    [Back]

     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.

     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:

     -d      Dictionary character set and order, i.e. only alphanumeric characters
 are compared.

     -f      Ignore the case of alphabetic characters.

     -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.

COMPATIBILITY    [Toc]    [Back]

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