Answers:
的组合,wmctrl
并xprop
提供了许多可能性。
范例1:
running_gui_apps() {
# loop through all open windows (ids)
for win_id in $( wmctrl -l | cut -d' ' -f1 ); do
# test if window is a normal window
if $( xprop -id $win_id _NET_WM_WINDOW_TYPE | grep -q _NET_WM_WINDOW_TYPE_NORMAL ) ; then
echo "$( xprop -id $win_id WM_CLASS | cut -d" " -f4- )"", window id: $win_id"
fi
done
}
在这种情况下,输出看起来像这样:
"Firefox", window id: 0x032000a9
"Gnome-terminal", window id: 0x03a0000c
"Thunar", window id: 0x03600004
"Geany", window id: 0x03c00003
"Thunar", window id: 0x0360223e
"Mousepad", window id: 0x02c00003
"Mousepad", window id: 0x02c00248
"Xfce4-terminal", window id: 0x03e00004
范例2:
running_gui_apps() {
applications=()
# loop through all open windows (ids)
for win_id in $( wmctrl -l | cut -d' ' -f1 ); do
# test if window is a normal window
if $( xprop -id $win_id _NET_WM_WINDOW_TYPE | grep -q _NET_WM_WINDOW_TYPE_NORMAL ) ; then
# filter application name and remove double-quote at beginning and end
appname=$( xprop -id $win_id WM_CLASS | cut -d" " -f4 )
appname=${appname#?}
appname=${appname%?}
# add to result list
applications+=( "$appname" )
fi
done
# sort result list and remove duplicates
readarray -t applications < <(printf '%s\0' "${applications[@]}" | sort -z | xargs -0n1 | uniq)
printf -- '%s\n' "${applications[@]}"
}
输出示例:
Firefox
Geany
Gnome-terminal
Mousepad
Thunar
Xfce4-terminal
您可以将函数添加到您的函数中,~/.bashrc
也可以从脚本文件运行它。
当您需要在窗口上执行操作(例如移动或调整大小)时,xdotool
和的功能wmctrl
就会显现出来。但是,我坚信,仅列出正在运行的程序和有关它们的信息,xprop
并且这qdbus
是两个足够的工具并进行安装xdotool
,wmctrl
除非用户希望使用这些程序具有其他功能-这是没有目的的任务。在这个答案中,我想用xprop
和提出两个脚本解决方案qdbus
。
请注意,我绝不反对xdotool
或wmctrl
。我本人已经广泛使用它们,但是与其他工具结合使用时,它们会变得更强大。以下是我使用它们的一些示例:
下面的脚本仅使用xprop提取活动窗口的列表,仅过滤出真实的窗口(而不是停靠类型为Unity Launcher或Unity Panel的suck)并显示其信息:
演示:
$ bash xprop_windows.sh
XID TYPE TITLE
--------------------------------
56623112| "x-terminal-emulator", "X-terminal-emulator"| "sakura"
81789126| "Navigator", "Firefox"| "Restore Session - Mozilla Firefox"

33554444| "gnome-terminal", "Gnome-terminal"| "\"Terminal\""
33554486| "gnome-terminal", "Gnome-terminal"| "\"Terminal\""
脚本来源:
get_hex_xids()
{
xprop -root -notype _NET_CLIENT_LIST | \
awk 'BEGIN{printf "ibase=16"}\
{gsub(/\,/," ");for(i=1;i<=NF;i++) \
if ($i~/0x/) printf ";%s",substr(toupper($i),3) }'
}
convert_hex2dec()
{
HEXIDS=$(get_hex_xids)
echo $HEXIDS | bc
}
print_header()
{
printf "%s\t%s\t%s\n" "XID" "TYPE" "TITLE"
printf "%s\n" "--------------------------------"
}
list_info()
{
convert_hex2dec | while read line;
do
TYPE=$( xprop -id $line _NET_WM_WINDOW_TYPE | awk -F '=' '{print $2}' )
if [ $TYPE != "_NET_WM_WINDOW_TYPE_NORMAL" ]; then
continue
fi
CLASS=$(xprop -id $line WM_CLASS | awk -F '=' '{print $2}' )
NAME=$( xprop -id $line _NET_WM_NAME | awk -F '=' '{print $2}' )
printf "\n%s|%s|%s\n" "$line" "$CLASS" "$NAME"
done
}
print_header
list_info
下面的代码执行基本相同的任务,但是它首先过滤掉应用程序,然后列出其子窗口,最后提供有关它们的信息。
样品运行:
$ bash ~/bin/qdbus_windows.sh
Name: Terminal
Active :false
Children:
33554486|false|""Terminal""
33554444|false|""Terminal""
--------------
Name: Firefox Web Browser
Active :false
Children:
82002372|false|"gui - How do I get a list of running applications by using the command line? - Ask Ubuntu - Mozilla Firefox"
81789126|false|"Restore Session - Mozilla Firefox"
--------------

代码本身:
#!/bin/bash
get_window_paths()
{
qdbus org.ayatana.bamf /org/ayatana/bamf/matcher org.ayatana.bamf.matcher.WindowPaths
}
get_running_apps()
{
qdbus org.ayatana.bamf /org/ayatana/bamf/matcher org.ayatana.bamf.matcher.RunningApplications
}
list_children()
{
qdbus org.ayatana.bamf "$1" org.ayatana.bamf.view.Children
}
window_info()
{
for window in "$@" ; do
XID=${window##*/}
TYPE=$(qdbus org.ayatana.bamf $window org.ayatana.bamf.window.WindowType)
NAME="$(qdbus org.ayatana.bamf $window org.ayatana.bamf.view.Name)"
ACTIVE=$(qdbus org.ayatana.bamf $window org.ayatana.bamf.view.IsActive)
MONITOR=$(qdbus org.ayatana.bamf $window org.ayatana.bamf.window.Monitor)
# printf "%s|%s|%s|%s\n" $TYPE $MONITOR $ACTIVE "$NAME"
printf "%s|%s|\"%s\"\n" $XID $ACTIVE "$NAME"
done
}
window_paths=( $( get_window_paths | tr '\n' ' ') )
apps_list=( $( get_running_apps | tr '\n' ' ' ) )
for app in ${apps_list[@]} ; do
#echo $app
printf "Name: "
qdbus org.ayatana.bamf $app org.ayatana.bamf.view.Name
printf "Active :"
qdbus org.ayatana.bamf $app org.ayatana.bamf.view.IsActive
printf "Children:\n"
# list_children $app
windows=( $( list_children $app | tr '\n' ' ' ) )
window_info "${windows[@]}"
printf "%s\n" "--------------"
done
命令稍微简单一些,但需要使用Unity的窗口堆栈dbus接口过滤掉输出。这本质上是我的功能.mkshrc
window_stack()
{
qdbus --literal com.canonical.Unity.WindowStack
/com/canonical/Unity/WindowStack \
com.canonical.Unity.WindowStack.GetWindowStack | \
awk -F '{' '{gsub(/\}|\]|,/,"");gsub(/\[/,"\n");print $2}' | \
awk '!/compiz/&&!/^$/ && $4!="\""$3"\"" { L[n++] = $0 }\
END { while(n--) print L[n] }'
}
样品运行:
$ window_stack
Argument: (usbu) 56623112 "x-terminal-emulator" true 0
Argument: (usbu) 82002372 "firefox" false 0
Argument: (usbu) 81789126 "firefox" false 0
Argument: (usbu) 33554486 "gnome-terminal" false 0
Argument: (usbu) 33554444 "gnome-terminal" false 0
qdbus用法示例:
wmctrl -l
可能是您想要的东西。首先安装
sudo apt-get install wmctrl
您还可以将其与系统监视器的列表结合使用,默认情况下,它显示“我的所有进程”,这意味着作为用户属于您的所有进程。
要仅具有应用程序名称,请运行:
编辑:
wmctrl -l|awk '{$3=""; $2=""; $1=""; print $0}'
0x03c000b3 0 avinash-Lenovo-IdeaPad-Z500 How list of running applications by command? - Ask Ubuntu - Mozilla Firefox
了有关Desktop,Hud等的一些额外信息。
wmctrl -l|awk '{out=""; for(i=2;i<=NF;i++){out=$out" "$i}; print $out}'
将添加到我的答案中。感谢您指出。
