我的桌面上有一个启动器，我想手动添加另一个具有相同图标的启动器。
当我转到现有启动器的首选项并单击图标时，它不会将我带到存储图标的文件夹，而只是带到我的主文件夹。
我如何才能找出启动器使用的图标在系统中的位置？
答案1
大多数情况下，图标将从您当前的图标主题中选择，而不是被称为绝对路径。
打开 Gedit
将启动器拖到 Gedit 窗口中
寻找
Icon定义：Icon=gnome-panel-launcher
然后你就可以找到图标某处，取决于/usr/share/icons您的主题。
下面是一个快速的 Python 脚本，可以为您找到正确的图标路径：
import gtk
print "enter the icon name (case sensitive):"
icon_name = raw_input(">>> ")
icon_theme = gtk.icon_theme_get_default()
icon = icon_theme.lookup_icon(icon_name, 48, 0)
if icon:
print icon.get_filename()
else:
print "not found"
将其保存在某处并运行python /path/to/script.py。
它看上去会像这样：
stefano@lenovo:~$ python test.py
enter the icon name (case sensitive):
>>> gtk-execute
/usr/share/icons/Humanity/actions/48/gtk-execute.svg
或者，您也可以四处寻找，/usr/share/icons直到找到所需的图标。
更简单：您只需复制并粘贴启动器并更改名称和命令即可
编辑2018
上述脚本的更新版本：
#!/usr/bin/env python3
import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
icon_name = input("Icon name (case sensitive): ")
icon_theme = Gtk.IconTheme.get_default()
icon = icon_theme.lookup_icon(icon_name, 48, 0)
if icon:
print(icon.get_filename())
else:
print("not found")

更多信息。
普通启动器实际上是 /usr/share/applications/ 中的 .desktop 文件。
例如：/usr/share/applications/usb-creator-gtk.desktop
（看https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html）
每个桌面文件都有一行指定图标，例如：
Icon=usb-creator-gtk
当没有路径（和文件扩展名）（如本例）时，表示在 /usr/share/icons/ 中的某处找到该图标，并且运行时使用的图标取决于当前主题，在某些情况下还取决于显示上下文（大小）。
从桌面文件中知道图标名称（不带扩展名），可以按如下方式找到它/它们：
$ find . -name "usb-creator-gtk*"
./hicolor/scalable/apps/usb-creator-gtk.svg
./Humanity/apps/32/usb-creator-gtk.svg
./Humanity/apps/16/usb-creator-gtk.svg
./Humanity/apps/22/usb-creator-gtk.svg
./Humanity/apps/24/usb-creator-gtk.svg
./Humanity/apps/64/usb-creator-gtk.svg
./Humanity/apps/48/usb-creator-gtk.svg

#!/usr/bin/env python3
from gi.repository import Gtk
icon_name = input("Icon name (case sensitive): ")
if icon_name:
theme = Gtk.IconTheme.get_default()
found_icons = set()
for res in range(0, 512, 2):
icon = theme.lookup_icon(icon_name, res, 0)
if icon:
found_icons.add(icon.get_filename())
if found_icons:
print("\n".join(found_icons))
else:
print(icon_name, "was not found")
将以上内容保存到文件中并使用 运行python3 /path/to/file。
之间的差异斯蒂法诺·帕拉佐原来的剧本是这样的：
- 这将找到图标的所有分辨率（不只是 48）
- 用途
gi.repository代替Gtk - 使用 Python 3 而不是 2
- 在其他方面略有调整

已将此作为 unix.stackexchange 上问题的奖励添加，并意识到在原始线程中分享它也不错...所以
这是另一个修改版本，它结合了 Stefano Palazzo 的 2018 版本和 kiri 版本的一些元素以及我自己的更改（脚本顶部的一些注释文档）。
#!/usr/bin/env python3
# ==========================================================================================
# This script is for looking up an icon file path based on the icon name from a *.desktop file.
# Parts of it are based on snippets provided by Stefano Palazzo and kiri on askubuntu.com
# https://askubuntu.com/questions/52430/how-can-i-find-the-location-of-an-icon-of-a-launcher-in-use
# ==========================================================================================
# The original version(s) simply prompted the user for the icon name.
# However, I have modified this version in the following ways:
# 1. Added ability to pass specific size as arg (e.g. --size=22 or --size=48, etc)
# 2. Added ability to pass icon names as arg (any other arg besides --size)
# Note: if --size is used with multiple icon names, then it is assummed
# that all of the icons in the search will be for the same size
# 3. Like kiri's version, I removed the hard-coded size of 48x48 and default to all sizes
# 4. Unlike kiri's version, you can optionally still search for a specific size (using #1)
# 5. Performance improvements from kiri's version (he was checking every even number from
# 0 to 500 -- so 250 iterations. I base mine off the values that actually existing under
# /etc/share/icons/hicolor - of which there were 17. So his is more flexible but
# mine should be quicker and more forgiving in terms of HDD wear and tear)
