将几行代码放入脚本中，以便在 gdb 中执行

tag-icon • tag-icon bash firefox gdb
将几行代码放入脚本中，以便在 gdb 中执行

我想创建一个脚本或者实际上是一个快捷方式来安静地浏览

#!/bin/bash
konsole -e firefox --debug
(gdb) handle SIGPIPE noprint nostop pass
(gdb) handle SIGSEGV noprint nostop pass
(gdb) run

这不起作用。我希望有人能帮助我。解决后，我可以告诉你这个故事。我可能会帮助很多人。

到目前为止我可以做到这一点：

使用以下方式创建 bash 脚本

#!/bin/bash
konsole -e firefox --debug

将其标记为可执行文件。双击以在终端中打开，等待我输入运行并输入

创建~/.gdbinit以下内容

handle SIGPIPE noprint nostop pass
handle SIGSEGV noprint nostop pass

bash您可以使用（ ）的此处文档<<将交互式命令传递给gdb：

#!/bin/bash
firefox --debug  <<'EOF'
handle SIGPIPE noprint nostop pass
handle SIGSEGV noprint nostop pass
run
EOF

检查Here Documents部分man bash以获得更多想法。

例子：

$ cat scr.sh 
#!/bin/bash
firefox --debug <<'EOF'
help
quit
EOF

$ bash scr.sh

好的，它起作用了。现在我知道如何在这里创建一个新行。它是 shift + enter。仅适用于编辑模式。也许 4 个空格可用....只有 600 个字符，这是怎么回事？

this is the code:
#!/bin/bash
firefox --debug <<'EOF'
handle SIGPIPE noprint nostop pass
handle SIGSEGV noprint nostop pass
run
EOF

不需要“konsole -e”......然后只需双击脚本，然后就可以删除gdbinit

谢谢你 heemayl。你拯救了许多沮丧的 Linux 用户的生命，他们的 Firefox 崩溃率太高了！很抱歉添加了上面的文字，但 konsole -e 不是必需的，这是我的错。我现在真的很好奇 EOF 是什么意思。
