Display any lines in file which contain string as a prefix.
Syntax look [-df] [-t termchar] string [file] As look performs a binary search, the lines in file must be sorted. Options: -d Dictionary character set and order, i.e. only alphanumeric characters are compared. -f Ignore the case of alphabetic characters (UPPER/lower). -t Specify a string termination character, i.e. only the characters in string up to and including the first occurrence of termchar are compared.
If file is not specified, the dictionary file /usr/share/dict/words is used, only alphanumeric characters are compared and the case of alphabetic characters is ignored.
Exits 0 if one or more lines were found and displayed, 1 if no lines were found, and >1 if an error occurred.
The return status is the exit status of the last command executed in consequent-commands, or zero if none were executed.
