Hi,
I just found this thread through Google.

My situation was similar, but the resolution was simple and different. It wasn’t related to the code at all.
I was on my Windows 7 machine connecting to my UNIX server through Notepad++ using the FTP plugin.

I was getting the same error mentioned here –
} ./test_script.sh
./test_script.sh: Command not found.

After looking at the initial things I was like “Doh!” and I checked the Notepad++ -> Edit Menu -> EOL Converstion settings and of course it was set to Windows and not UNIX.

After I set it to UNIX and uploaded the latest copy, the program executed without problems.

Just thought I’d note that here in case people have the same issue.

Peace,
Justin

do you happen to know where to look for that specific message “command not found” in centos? I’d like to chnage it to something else but am not able to locate it anywhere… have found it in other distros like ubuntu/debian – they have it in /etc/bash.bashrc and they even have such package by name command-not-found… and I was able to replace it with desired content… so, is there a way to perform the same on centos?

Hi,
I ran into a “make: arm_v5t_le-gcc: command not found” with “make” facility while I was doing compile a program.
I ran this compiling with arm_v5t_le-gcc full path, I got the same error.
I checked the $PATH, and the the arm_v5t_le-gcc is in there.
I checked with “locate”, and the arm_v5t_le-gcc is there.
I checked with “which”, and the arm_v5t_le-gcc is there.
I checked the permission, and the arm_v5t_le-gcc is 755.
What else may cause this “command not found” error? Any guys can help me?
Thank you very much!
Cheer,
Justin
