look

look [options ] string [file ]

Solaris only. Look through a sorted file and print all lines that begin with string . Words may be up to 256 characters long. This program is potentially faster than fgrep because it relies on the file being already sorted, and can thus do a binary search through the file, instead of reading it sequentially from beginning to end.

With no file , look searches /usr/share/lib/dict/words (the spelling dictionary) with options -df .

Options

-d

Use dictionary order. Only letters, digits, space, and tab are used in comparisons.

-f

Fold case; ignore case distinctions in comparisons.

-t char

Use char as the termination character, i.e., ignore all characters to the right of char .
