I'm implementing a shell in C that supports piping, output redirection, and background processing, and a few other commands. I was wondering how I'd go about implementing the output redirection. So, I'd open a file and I'd fork and execute the command. But how would I get stdout into the file? Any... (10 Replies)

STARTFLUXBOX(1) Fluxbox Manual STARTFLUXBOX(1)NAME
startfluxbox - start a fluxbox session
SYNOPSIS
startfluxbox
DESCRIPTION
startfluxbox is a script which runs the file ~/.fluxbox/startup If it doesn't exist it will be generated.
startfluxbox should be started from your ~/.xinitrc if you use startx, or ~/.xsession if you run a display manager, like xdm.
FILES
~/.fluxbox/startup
This file contains all commands that should be executed before fluxbox is started. The initial file contains helpful comments for
beginners. It also starts fluxbox.
EXAMPLES
The default ~/.fluxbox/startup is as follows:
#!/bin/sh
#
# fluxbox startup-script:
#
# Lines starting with a '#' are ignored.
# Change your keymap:
xmodmap "$HOME/.Xmodmap"
# Applications you want to run with fluxbox.
# MAKE SURE THAT APPS THAT KEEP RUNNING HAVE AN ''&'' AT THE END.
#
# unclutter -idle 2 &
# wmnd &
# wmsmixer -w &
# idesk &
# And last but not least we start fluxbox.
# Because it is the last app you have to run it with ''exec'' before it.
exec fluxbox
# or if you want to keep a log:
# exec fluxbox -log "$fluxdir/log"
If you need to start applications after fluxbox, you can change the exec fluxbox line above to something like this:
exec fluxbox &
fbpid=$!
sleep 1
{
xsetroot -cursor_name left_ptr -fg white -bg black &
ipager &
gkrellm2 &
} &
wait $fbpid
So xsetroot, ipager, and gkrellm2 will all be started after fluxbox, after giving fluxbox 1 second to startup.
For more details on what else you can do in this script, see sh(1), or the documentation for your shell.
