Command not found

nfis · 12-20-2002, 06:18 AM

I have a program that is compiled using Slackware Linux version 2.0.29.
To take benefit of evolution in hardware, filesystem etc., I have purchased Slackware Linux 8.1.
But when I try to run the program (using the full path and with the execute property set), the Linux responses with the message “Command not found”.
The question is: Is this because of the difference in the Slackware Linux distribution or is this happening because I do something wrong?

Someone who knows?

Best regards,
Johan L. Aase

It shouldn't be because it's a different version of slackware. Does the program you run try to start any other programs which could cause it to report the error "Command Not Found"?
What does the exact error look like? Usually if you type the full path then you should get something like:
bash: /bin/foo: No such file or directory

The command not found you would only get if you don't add the full path and the command can't be found in your path either.

The program is a standalone executable and is not trying to start any other programs.
The message reported back after I try to run the program is:
“/usr/local/nfis/bin/nfis: Command not found”

(Shell in us is tcsh)
As additional information I can mention that I copied a program found in the Slackware Linux 8.1 distribution to the same location as the nfis file I’m trying to run, and that worked like it should (I even renamed it to another name to be sure it didn’t run the one in the path)

What does 'file /usr/local/nfis/bin/nfis' tell you? I have no experience using tcsh. Do you get similar results if you try another shell?

When using the bash shell, I get this message:
“bash: “/usr/local/nfis/bin/nfis: No such file or directory”

Sorry I hit the enter button a little bit early :-)
The reply should be:

When using the bash shell, I get this message:
“bash: “/usr/local/nfis/bin/nfis: No such file or directory”

Running the “file /usr/local/nfis/bin/nfis” command, the system replies:
“/usr/local/nfis/bin/nfis: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dunamically linked (uses shard libs), not stripped”

(Still running the bash shell)

Ok now that looks really confusing. Bash can't find it but file can.
What about if you do:
cd /usr/local/nfis/bin/ && ./nfis

Sorry but I'm out of ideas, not very creative on a friday afternoon.

Maybe one of these will help get you more info:

strace -o trace1.out /usr/local/nfis/bin/nfis
strace -o trace2.out bash -c /usr/local/nfis/bin/nfis

First of all: Thanks for your effort!

The command "cd -usr-local-nfis-bin && ./nfis" gave the same result as above (No such file or directory)

The "strace -o trace1.out /usr/local/nfis/bin/nfis" gave the result:
execve("/usr/local/nfis/bin/nfis", ["/usr/local/nfis/bin/nfis"], [/* 36 vars */]) = 0

The other strace call gave a lot more information (about 6 KB), which I will try to interpret.

Thanks again.

if your first line is #!/bin/tcsh and there is no 'tcsh' in your /bin, then this problem occurs. This sounds trivial but sometimes small things cause big problems.
