change the top line to
#!/bin/bash

or wherever your bash is at

right now it is trying to run as sh not bash

Bourne shell for would not allow that kind of syntax... It only allows
for name [ in word ... ] do list; done
To emulate what you want, you'd need something like
#!/bin/sh
touch test1
i=1
while [ $i -lt 11 ]
do
  echo $i >> test1
  i=`expr $i + 1 `
done
# End of scriptlet

Bash (which on many, if not most, distributions _is_ /bin/sh) has an alternative
for ((expr1; expr2; expr3)) do list; done
that could be used as you want
#!/bin/bash
touch test1
for ((i=1;$i <= 10; i++))
do
  echo $i >> test1
done
# End of scriptlet

Not all shells append (>>) redirection would create a non-existing file, so the "thouch test1" is to avoid any uncertainty.

For the current shell:
export PATH=${PATH}:/test

For any bourne shell compatible shell... Making it more "permanent":
Enter the above line into your $HOME/.profile file.

Also, if you intend to test out how shells really work, do study the manpages. All we've said so far could be read from them:-).

man bash sh ksh zsh ash csh tcsh
or whatever shells you've installed:-)

Personally i would of used this, its quicker to type;

------------------------------------------------------------
#!/bin/sh
for i in 1 2 3 4 5 6 7 8 9 10
do
echo $i >>test
done
------------------------------------------------------------


And its isn't complicated ...

Yes but I want to fill a file with number starting from 1 to 3000.
If I want to make permanent the PATH what can I do?
I'm using bash shell and I want to do my work as root so what profile I have to change?
I have made a lots of test and do I found that in the PATH there are 4 time the directory /test how can I erase it?

Bash will read the .profile in roots home directory, but you could also place it in ~root/.bash_profile ... man bash, and look at the differences of what files get read at login (or "su - root") and a plain "su root".

You only need set the PATH as in the above once ... If you have messed up your path you can reset it by logging out/back in (duh:-), or by
echo $PATH
to see what it contains, and then
export PATH=<the different paths you need, separated by ":">
Using the mouse (X or gpm (or similar) on the console) to cut-n-paste might be a good idea:-).

Since the target here is 3000, UkWizards (in other situations perfectly OK) solution will be less then useable.
In my example scripts, simply replace 11 with 3001´for the first, or 10 with 3000 for the latter:
#!/bin/sh
touch test1
i=1
while [ $i -lt 3001 ]
do
  echo $i >> test1
  i=`expr $i + 1 `
done
# End of scriptlet
.... or ...
#!/bin/bash
touch test1
for ((i=1;$i <= 3000; i++))
do
  echo $i >> test1
done
# End of scriptlet

Thanks liddler, but I'm actually partway serious... When CleanupPing is run, there's a lot of "I'm right" or "S/he is right" or "We're all right"... And not being a native anglophone, I'd like to find a nice way of saying it (and with a tad more variation:-):-).

Glenn,
The only variations that might be useful in long question (though not in this case) is to point out which particular comments answered the Question.  Sometimes novice readers might struggle when searching PAQ with lots of comments to know which comment will fix their problem best.

...and your English is as good as mine, and I'm a native :->
