NAME
look—Display lines beginning with a given string
SYNOPSIS
look [–dfa] [–t termchar] string [file]
DESCRIPTION
The look utility displays any lines in file that 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/dict/words is used, only alphanumeric characters are compared, and the case of alphabetic characters is ignored.
OPTIONS
| Options | Description |
| –d | Dictionary character set and order; that is, only alphanumeric characters are compared. |
| –f | Ignore the case of alphabetic characters. |
| -a | Use the alternate dictionary /usr/dict/web2. |
| –t | Specify a string termination character; that is, 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.
