SYNOPSIS

lookat [ --help ] [ filename ] [ dir_name ]

DESCRIPTION

"lookat" (or "bekijk" in the Dutch version) is a program to view Un*x text files and manual pages.

Under DOS I used list.com to view text files. I didn’t find such a program under my favorite OS, GNU/Linux. The standard Un*x utilities ( more, less, view ...) weren’t userfriendly enough. For this reason I created "lookat".

OPTIONS

--help This option displays a help text.
file_name view file_name
dir_name change the current directory to dir_name

BUGS

None known yet, when you find one you let me know :-)

USAGE

There are four ways to start lookat :

* by just typing ’lookat’, after the program is started you can select the file you want to view.

if there is already data on stdin, lookat will read the from stdin, and display the contents of stdin

example:
ls | lookat
* type ’lookat dir_name’, change the current directory to dir_name. When the program is started you can select the file you want to view.
* by typing ’lookat <filename>’, the file with <filename> will automatically be loaded.
* in combination with "man"
examples :
man -Plookat ls
export PAGER=lookat; man ls
If you like "lookat" as your manual page viewer you can put the next lines in your /etc/profile
alias man="man -Plookat"
After you have loaded a file, the following keys can be used:
Keys:

<-, C-b : move left / back

CONFIGURATION

Note:
The format of the configuration file has changed, please remove the "=" sign. The old configuration files will still work, but may not be supported in the future.
lookat uses two configuration files a global configuration file ( /usr/local/etc/lookat.conf ) and a user configuration file ( $HOME/.lookat ) if the user’s configuration file exists the global is ignored.

If the configuration files aren’t available the defaults are used.

CONFIGURATION DIRECTIVES

cursor  on|off      

turn the cursor on / off
give_notice  on|of

give notice on exit on / off
.[extension] "external cmd"

create a new type
If a filename matches a type the external command will be used to open the file. A typical usage are gzipped files:
.gz "gzip -cd"
The type order is important lookat will compare the filename with the types starting with the first type and continues until a type matches a filename.
So if you want to define a type for ".gz" and ".tar.gz" files you have to put the .tar.gz type first.
color object foreground background [ attribute ]

If your terminal supports colors, this directive can be use to modify the color of certain objects. Valid objects are: view, view_bold, view_italic, main_menu, main_menusel, main_menuhot, main_menuhotsel, status_bar, win1, win1_edit, win1_menu, win1_menusel, win1_menuhot, win1_menuhotsel, win2, win2_edit, win2_menu, win2_menusel, win2_menuhot, win2_menuhotsel, view_found.
Valid colors are: white, black, green, magenta, blue, cyan, yellow, red.
Valid attributes are: normal, bold, underline, reverse, and standout.
mono object foreground_attribute [ background_attribute ]

If your terminal doesn’t support color, you can still assign foreground and background attributes to certain objects.
