You might also wish to check this out:

http://www.macports.org/

They have a Scala port and this makes installation pretty simple.

I will try that.

I put it in .profle instead because that is where I put my JAVA_HOME and this
time when I typed in scala
this is what happened:

p, li { white-space: pre-wrap; }Woah... Are you running Scala in a chroot or something? Or have you accidentally deleted all of the standard UNIX tools? Because those errors are really severe.

My guess is that you've changed your whole PATH instead of appending to it. Please try:
export PATH=$SCALA_HOME/bin:$PATH

instead of:
export PATH=$SCALA_HOME/bin

...which is what you probably did.

It looks like I accidentally deleted all of the standard Unix tools.
When I say "which sudo"
it says" -bash: which: command not found.
if I say "sudo pico .profile
it says" -bash: sudo: command not found

But I cannot understand how I did that. What do you suggest I do about the
situation?

It's probably more likely that your PATH variable is messed up (or even
empty). Check that.

Randall Schulz

p, li { white-space: pre-wrap; }I'll say it again: Your PATH is destroyed, but your tools are still there. On Linux, I would do:
export PATH=/usr/bin:/bin
...but I think that the UNIX executables are stored elsewhere on a Mac.

To be absolutely certain that everything is available, type:
export PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin

That fixes your PATH temporarily (so that you regain some basic paths) and then you can edit your .profile to what I posted before. A relogin should fix everything after that.

p, li { white-space: pre-wrap; }Oh and BTW, don't use sudo when you want to edit your .profile file. You own the file yourself, so you don't need any extra privileges that sudo gives you.

nano .profile
or
pico .profile
or
vim .profile
...is enough.

Actually I bet you just messed up your path...
type: echo $PATH
and see if it has anything on it.
Mine looks like this:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin
The stuff in "opt" is for MacPorts.

I type in echo $PATH and it returned:
/usr/local/share/scala-2.7.5.final/bin

What's you .profile look like?
Mine looks like:## Your previous .profile  (if any) is saved as .profile.mpsaved# Setting the path for MacPorts. export PATH=~/bin:/opt/local/bin:/opt/local/sbin:$PATHexport SCALA_HOME=/usr/local/share/scala#export JAVA_HOME=/opt/local/share/java/openjdk6export ANT_OPTS=-Xmx2galias ll='ls -la'
Notice that when it alters the PATH is concatenates it with the existing PATH.  It looks like wherever scala is being added to the PATH is destroying your existing PATH.

You guys are right. I seem to have messed up the PATH variable. I can run
"pico" with "/usr/bin and I was able to run pico.

That worked! Sudo, pico, all started working again. Scala fired up without
issues.
Now my question is: when I issued the command: export PATH="....
Where can I find this PATH variable. It is certainly not written to the
.profile file.

In general if I want to add the path to any new application, say ANT, then I
have to issue the same export PATH="$ANT_HOME/bin:$PATH, etc, right?

PATH is an environment variable. If you issue export PATH=... in a
running shell, then that value persists while that shell does, rather
like a local variable in Scala. Rather unlike a local variable in
Scala, it is automatically propagated to any processes that the shell
launches.

If you want it to be permanent, you need to write that line in a file
that gets 'sourced' when a new shell starts, such as ~/.bashrc.
Spending some time learning your shell would probably be useful. man
bash.

You are correct about ant.
