XDG-OPEN＆＃x27;分段故障＆＃x27;：花了很长时间然后扔错误

好吧，我注意到XDG-OPEN命令无法按预期的操作文件或URL工作经过深入的调查，我发现以下

跟踪：

bash -x xdg-open "https://suckless.org"

运行上线后，我发现代码进入了无限的递归环，该循环会导致以SEG故障终止问题的功能： /usr/bin/xdg-open：819，

for d in $dir/*/; do
    [ -d "$d" ] && search_desktop_file "$default" "$d" "$target"
done

但是为什么首先会发生这种情况，那很简单，我将在下面讨论

根本原因：

XDG-OPEN尝试首先尝试获得全部目标应用程序的可能位置
- 〜/.local/share/申请
- /usr/local/share/申请
- /usr/share/application
如果有任何孩子dir，它会递归递归，
当目录名称具有空间时，问题就会发生
- 在我的情况下，就像这个

ls -la〜/.local/share/applications // wine // program // rockstar Games/
LS：无法访问 '〜/.local/share/applications // wine // program // rockstar'：没有这样的文件或目录游戏/：总计12 drwxrwxrwx 3 void void 4096 2月26日 19:54。 drwx ------- 43 void void 4096 5月29日12:32 .. drwxr-xr-x 5 void void 4096 5月24日22:36 Epic-Games商店这使该工具可以在一个非常不同的文件中查找，从而使lop loop
循环循环

：

更容易的修复是更改DIR名称并删除任何空间，如果您只能将桌面文件保留在〜/.local/.local/share//share/，则更好申请

原文

well I noticed xdg-open command not working as expected for opnening files or urls
and after a deep investigation I found the below

Trace:

bash -x xdg-open "https://suckless.org"

after running the above line I found the code enters an infinite loop of recursion which cause to terminate with seg fault
the function with the problem:
/usr/bin/xdg-open:819

for d in $dir/*/; do
    [ -d "$d" ] && search_desktop_file "$default" "$d" "$target"
done

But why this happens in the first place, well it was fairly simple which I'm going to discuss below

Root Cause:

xdg-open tries first to get all possible locations for target applications like
- ~/.local/share/applications
- /usr/local/share/applications
- /usr/share/application
if there's any child dir there it loop throug it recursively
the problem happens when a directory name has a space
- in my case it was like this

ls -la ~/.local/share/applications//wine//Programs//Rockstar Games/
ls: cannot access
'~/.local/share/applications//wine//Programs//Rockstar': No such file
or directory Games/: total 12 drwxrwxrwx 3 void void 4096 Feb 26
19:54 . drwx------ 43 void void 4096 May 29 12:32 .. drwxr-xr-x 5
void void 4096 May 24 22:36 epic-games-store
this got the tool to look up in a very different files which causes to loop infintly

Fix:
