fte

FTE(1)							      General Commands Manual							    FTE(1)

NAME

       fte - Text editor

SYNOPSIS

       fte  [[options] files ...]

       xfte [[options] files ...]

       vfte [[options] files ...]

       nfte [[options] files ...]

       sfte [[options] files ...]

DESCRIPTION

       This manual page documents briefly the fte.

       Some detailed documentation is available html format, see below.

       fte is a powerful text editor which closely resembles Borlands programming editors for M$-DOS, but is far more flexible and configurable.

OPTIONS

       fte uses a command line syntax, which is a little bit different from most of Debian GNU/Linux apps.

       -h -? --help
	      Help on command line options.

       -!     Ignore any external configuration file and use internal configuration.

       -l<line>[,<column>]
	      Go to line (and column) in next file on command line.

       -#<line>[<,column>]
	      Same as -l. Do not use this option.

       -m[<mode>]
	      Set mode for next files to <mode>. If just plain -m, then use default mode.

       -C[<.cnf>]
	      Use specified configuration file (compiled). Plain -C does the same as -!.

       -D[<.dsk>]
	      Load/save desktop from file <.dsk>. If no argument, disable desktop load/save.

       -H[<.his>]
	      Load/save history from file <.his>. If no argument, disable history load/save.

       -T<tagfile>
	      Load 'tagfile' at startup.

       -t<tag>
	      Lookup tag 'tag' and display file containing it.

       --     The rest of the arguments are not options, but filenames.

       -+     The next argument is not an option even if starting with a '-'.  Useful when loading files that begin with a -.

       -noi18n
	      Do not use locales in xfte - useful if you have incorrect locales.

       -noxmb Do not use XMB functions in xfte - useful if you have incorrect locales and you want to use just english fonts.

       -font  Select XWindow font to use with xfte. See VIOFONT also.

ENVIRONMENTAL VARIABLES

       This is list of variable which might change behavior of some internals of fte.

       VIOFONT - select font used by xfte

       ISOCONSOLE - when set, vfte is usign ascii symbols to draw tables. This is useful when iso latin charset is used on console.

EXAMPLES

       fte -mBIN /usr/bin/vfte
	      load /usr/bin/vfte in BIN mode

       fte -mBIN -+ -bla-
	      load file -bla- in BIN mode

       fte -l100,30 win.c
	      go to (100,30) in win.c

       fte window.cpp
	      load file window.cpp

       fte -- -1 -2 -3 -4 -5 -6
	      load files -1, -2, -3, -4, -5, -6

       fte -D -H fte.dsk fte.his
	      disable desktop and history loading and saving and load files fte.dsk and fte.his

FILES

       ~/.fterc
       /usr/local/etc/fte/system.fterc
       /etc/fte/system.fterc

       Default	configuration files. Includes all keybindings and menus compiled with cfte(1) from config files in /usr/share/doc/fte/config-exam-
       ple.tar.gz.
