+search, +nosearch

Use (or do not use) the search list provided in /etc/resolv.conf.

The default is not to use the search list.

+time=t

Timeout for queries, in seconds. The default is 5, and the

minimum is 1.

+tries=n

The number of times to retry UDP queries. The default is 3,

and the minimum is 1.

dir

dir [options] [file]

List directory contents. dir is equivalent to the command ls -C -b

(list files in columns, sorted vertically, special characters escaped),

and it takes the same arguments as ls. This is an alternate invoca-

tion of the ls command and is provided for the convenience of

those converting from Microsoft Windows and the DOS shell.

dircolors

dircolors [options] [file]

Set the color options for ls by changing the LS_COLORS environ-

ment variable. If you specify a file, dircolors will read it to

determine which colors to use. Otherwise, it will use a default set

of colors.

Options

The program takes three options in addition to the standard --help

and --version flags:

-p, --print-database

Display the default colors. You can copy this information into

a file and change it to suit your preferences, and then run the

program with the file as its argument to set the colors to your

new values.

-c, --csh, --c-shell

Use csh (C shell) syntax when setting the LS_COLORS

variable. ...
