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.  onlyalphanumeric characters are compared.


-fIgnore the case of alphabetic characters.-tSpecify a string termination character, i.e. only thecharacters  in  string  up to and including the firstoccurrence of termchar are compared.The look utility exits 0 if one or more lines were found anddisplayed,  1  if  no  lines  were found, and __FILES__

__COMPATIBILITY__


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