The simple way"Bash simple curses" give you some basic functions to quickly create some windows on you terminal as Xterm, aterm, urxvt...
An example is given: bashbar. Bashbar is a monitoring bar
... [More]
that you can integrate in tiling desktop (Xmonad, WMii...)
The goal of Bash Simple Curses is not done (not yet) to create very complete windows. It is only done to create some colored windows and display informations into.
You are using Bash simple curses ? Please Click on following button !
.gadget-title {
margin-bottom: 2px;
}
function resizeIframeHandler(opt_height) {
var elem = document.getElementById(this.f);
if (!elem) return;
if (!opt_height) {
elem.style.height = undefined;
}
else {
opt_height = Math.max(10, opt_height);
elem.style.height = opt_height + 'px';
}
}
gadgets.rpc.register("resize_iframe", resizeIframeHandler);
gadgets.rpc.register('set_title', function(title) {
var elem = document.getElementById(this.f + '_title');
if (elem) {
elem.innerHTML = gadgets.util.escape(title);
}
});
Why ?Because bash is very usefull, there are command to do whatever you want. With curses you can create a little bar to display informations every second, you can change an output command to display a report...
So, we need an easy and usefull library to quickly create this kind of views. This is why you can try Bash Simple Curses
Example: the bashbarBash bar is the given example that show system informations. You only have to resize your terminal window and place it on left or right. This screenshot is made on Xmonad:
this is the code used:
#!/bin/bash
. `dirname $0`/simple_curses.sh
main (){
window "`hostname`" "red"
append "`date`"
addsep
append_tabbed "Up since|`uptime | cut -f1 -d"," | sed 's/^ *//' | cut -f3- -d" "`" 2 "|"
append_tabbed "Users:`uptime | cut -f2 -d"," | sed 's/^ *//'| cut -f1 -d" "`" 2
append_tabbed "`awk '{print "Load average:" $1 " " $2 " " $3}' < /proc/loadavg`" 2
endwin
window "Memory usage" "red"
append_tabbed `cat /proc/meminfo | awk '/MemTotal/ {print "Total:" $2/1024}'` 2
append_tabbed `cat /proc/meminfo | awk '/MemFree/ {print "Used:" $2/1024}'` 2
endwin
window "Processus taking memory and CPU" "green"
for i in `seq 2 6`; do
append_tabbed "`ps ax -o pid,rss,pcpu,ucmd --sort=-cpu,-rss | sed -n "$i,$i p" | awk '{printf "%s: %smo: %s%%" , $4, $2/1024, $3 }'`" 3
done
endwin
window "Last kernel messages" "blue"
dmesg | tail -n 10 > /tmp/deskbar.dmesg
while read line; do
append_tabbed "$line" 1 "~"
done < /tmp/deskbar.dmesg
rm -f /tmp/deskbar.dmesg
endwin
window "Inet interfaces" "grey"
_ifaces=$(for inet in `ifconfig | cut -f1 -d " " | sed -n "/./ p"`; do ifconfig $inet | awk 'BEGIN{printf "%s", "'"$inet"'"} /adr:/ {printf ":%s\n", $2}'|sed 's/adr://'; done)
for ifac in $_ifaces; do
append_tabbed "$ifac" 2
done
endwin
}
main_loop 1Another Examplethis capture shows you that you can do whatever you want:
Code is:
#!/bin/bash
source $(dirname $0)/simple_curses.sh
main(){
window "Test 1" "red" "33%"
append "First simple window"
endwin
col_right
move_up
window "Test 2" "red" "33%"
append "Multiline is allowed !!!\nLike this :)"
append "This is a new col here."
endwin
window "Test 3" "red" "33%"
append "We can had some text, log..."
endwin
window "Test 4" "grey" "33%"
append "Example using command"
append "`date`"
append "I only ask for date"
endwin
col_right
move_up
window "Test 5" "red" "34%"
append "We can add some little windows... rememeber that very long lines are wrapped to fit window !"
endwin
window "Little" "green" "12%"
append "this is a simple\nlittle window"
endwin
col_right
window "Other window" "blue" "22%"
append "And this is\nanother little window"
endwin
}
main_loopHow nice !And just with libcaca "img2txt" command, you can have fun:
Cool, isn't it ? [Less]
