Shells won't automatically search the local directory unless &quot;.&quot; is part of your path, in which case you have to prepend things with &quot;./&quot;.

Try ./hello

Shells won't automatically search the local directory unless "." is part of your path, in which case you have to prepend things with "./".

Hello, <br />
&nbsp; I am a newcomer to linux and just installed RedHat 7.0 in my PC. I wrote a very simple C program such as printing Hello World on the screen and complied the source code by typing <br />
&nbsp; &nbsp;gcc -o hello hello.c<br />
The compling is Ok and a file called hello was generated.<br />
But when i type hello to excute, it gave me such message:<br />
bash: command hello not found.<br />
<br />
I am really not familia with linux. Is anything wrong with the system? Or do i have to change any system file(such as .cshrc in Unix)?<br />
<br />
Thank you.
