Refreshing 1.9 build

[Bil Kleb]

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 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.

Ah, yes.

Thank you,
