How to execute a program in linux after compiling it?
提问by yrazlik
I am compiling a C code in linux with the following command:
我正在使用以下命令在 linux 中编译 C 代码：
gcc -o myprogram myprogram.c
If I hadn't given a name to it, I could have simply written the command ./a.outto execute it. But now, to execute the program I just write "myprogram" to the command line, but it says "command not found". What can I do to execute it?
如果我没有给它命名，我可以简单地编写命令./a.out来执行它。但是现在，要执行该程序，我只需将“myprogram”写入命令行，但它显示“未找到命令”。我能做些什么来执行它？

It's possible that the current directory (".") isn't on your PATH. (You can check this by typing echo $PATH, this is a list of directories delimited with" :". "." should be in the list if you want to run something in the current directory.)
当前目录 (" .") 可能不在您的PATH. （您可以通过键入来检查这一点echo $PATH，这是一个以“ :”分隔的目录.列表。如果您想在当前目录中运行某些内容，“ ”应该在列表中。）
If the current directory isn't on your PATH, you'll need to type ./myprogram(or whatever the correct path is).
如果当前目录不在您的 中PATH，您需要输入./myprogram（或任何正确的路径）。

./myprogram
should do the trick.
应该做的伎俩。
(But really... have you looked at the contents of the directory after compiling the program "without name"? Or do you think ./a.outis a magic sequence Bash recognizes?)
（但真的……你有没有在编译“无名”程序后查看目录的内容？或者你认为./a.out是Bash识别的魔术序列？）
