Hi,

Is there a simpler way to refresh my Ruby 1.9 build?  
Here’s what I’m currently using on my OS X box:

#!/bin/sh

# 

# To refresh Ruby 1.9 build after an initial

# 

# svn co [http://svn.ruby-lang.org/repos/ruby/trunk](http://svn.ruby-lang.org/repos/ruby/trunk) ruby

svn up

VERSION=`grep 'RUBY_VERSION ' version.h | awk '{print $3}' | sed -e's/"//g'`  
SUFFIX=`grep RUBY_RELEASE_CODE version.h | awk '{print $3}'`

echo “Building ${VERSION}-${SUFFIX}”   
&& mkdir ${VERSION}-${SUFFIX}   
&& cd ${VERSION}-${SUFFIX}   
&& …/configure --prefix=/usr/local --program-suffix=19   
&& make   
&& sudo make install

Later,

---

You can use set -e.

I’m a bit slow… can you explain further how  
I might use ‘set -e’?

Thanks,

Setting -e option in a shell script causes the shell to exit  
immediately if a command exits with a non-zero status.

So you can write many commands without && and \s.

set -e  
echo “Building ${VERSION}-${SUFFIX}”  
mkdir ${VERSION}-${SUFFIX}  
cd ${VERSION}-${SUFFIX}  
…/configure --prefix=/usr/local --program-suffix=19  
make  
sudo make install

A difference is that it exits with a non-zero status by -e.
