SSH returned this, what does it mean?

[Doood]

I really don't know too much about running ssh commands other than simple tasks so bear with me.

I tried to run ApacheBench on my server using a url with lots of variables in it. Apparently ApacheBench is not installed on this server and this is what it showed after I tried to run it.

# ab -n 100 -c 10 http://www.example.com/script.php?var=123&var1=500&var2=60&var3=10&var4=20&var5=15&var6=Arial&var7=center&var8=FFFFFF&var9=000000&var10=FFFFCC&var11=006699&var12=1

root@server [~]# -bash: ab: command not found

[1] Exit 127    ab -n 100 -c 10 http://www.example.com/script.php?var=123
[10] Done     var9=000000
[11]- Done     var10=FFFFCC
[12]+ Done     var11=006699

It says "Done" as if it actually did something or changed some setting, but I really don't know what all that means.

ApacheBench output looks something more like:

This is ApacheBench, Version 1.3c <Revision: 1.41 > apache-1.3
Copyright (c) 1996 Adam Twiss, Zeus Technology Ltd, [zeustech.net...]
Copyright (c) 1998-1999 The Apache Group, [apache.org...]

..etc..

ApacheBench is just for checking basic request handling, and it's not intended to be an exhaustive benchmarking program. Your test URI with all of the parameters no doubt confused the little program.

"&" is for starting a process in the background.

And "[X] PID" is the output for newly started processes.

So in effect, you ran commands like "var2=60", "var4=20", etc. which failed because such executables don't exist.

You need to include your parameter inside quotes if it contains "&".
