NAME

look - display lines beginning with a given string

SYNOPSIS

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

DESCRIPTION

The utility displays any lines in file which contain string as a prefix. As 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 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

COMPATIBILITY

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.
