NAME

SYNOPSIS

DESCRIPTION

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

USAGE

* 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 ->, C-f : move right / forward arrow up, C-p : move up / previous line arrow down, C-n : move down / next line PgUp, u : move up a screen PgDwn, d : move down a screen HOME : go to the beginning of a line END : go to the end of a line o : open a new file t,< : go to top (start of file) b,e,> : go to the last line (end of file) g : go to a line number /,z,s,f : search for a string F3, n, c, v,   : continue search F9 : menu ALT+f : file menu ALT+g : go menu ALT+s : search menu ALT+h : help menu F10,ESC,q : quit program F1,h,? : view this help file r : rebuild screen

When you press F9 you get access to the pull-down menus, most of the functions are also available through the keyboard (see above).

File|Open or 'o':

When you select this function you get a window, at the left side of the window you get the files of the current directory. By selecting a file it will be loaded. At the right size of the window you see the directories, by pressing the TAB key you are able to switch between the file and the directory selection. By selecting a directory with ENTER you change the current directory. With the ESC key you cancel the file open operation.

After you select this function you will see a window which asks you to give a string. The searching can been done on two ways, with or without case sensitivity. By pressing the TAB key you can select -with SPACE or ENTER- how to search at

CONFIGURATION

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.
