look
LOOK(1) BSD General Commands Manual LOOK(1)NAME
look -- display lines beginning with a given string
SYNOPSIS
look [-df] [-t termchar] string [file]
DESCRIPTION
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 char-
acters 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.
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 incor-
rect and the current man page matches the historic implementation.
