PROGRAM:
NAME
look — display lines beginning with a given string
SYNOPSIS
look [-bdf] [-t termchar] string [file ...]
DESCRIPTION
The look utility displays any lines in file which contain string as a prefix.
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.
The following options are available:
-b Use a binary search on the given word list. If you are ignoring case with -f or
ignoring non-alphanumeric characters with -d, the file must be sorted in the same
way. Please note that these options are the default if no filename is given. See
sort(1) for more information on sorting files.
-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.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of the look
utility. Their effect is described in environ(7).
