LOOK(1) BSD Reference Manual LOOK(1)
look - display lines beginning with a given string
look [-df] [-t termchar] string [file]
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 sort- ed. 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. The options are as follows: -d Dictionary character set and order, i.e., only alphanumeric char- acters are compared. -f Ignore the case of alphabetic characters. -t termchar 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, or >1 if an error occurred.
/usr/share/dict/words the dictionary
The original manual page stated that tabs and blank characters partici- pated in comparisons when the -d option was specified. This was incorrect and the current man page matches the historic implementation.
The look command appeared in Version 7 AT&T UNIX. MirOS BSD #10-current June 14, 1993 1
