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 characters is ignored.
The following options are available:
|
| -d -, --alphanum
|
| |
Dictionary character set and order, i.e., only alphanumeric characters
are compared.
|
| -f -, --ignore-case
|
| |
Ignore the case of alphabetic characters.
|
| -t -, --terminate termchar
|
| |
Specify a string termination character, i.e., only the characters
in
string
up to and including the first occurrence of
termchar
are compared.
