Understand the concept is not to automate everything. but I did find the
constant checking for .tar.gz vs. .tar.bz2 annoying. So I came up with
this.
Place it in /home/lfs during Chapter 5 and/or in $LFS/root for use during
chapter 6. Invoke as:
. ~/prep package-archive
Don't forget the dot first (otherwise, the cd command doesn't stick - you'll
find yourself doing a "huh what?" because you aren't in the directory you
expect). Also, if you mess up the package-archive name, such as forgetting
the extension, you can find the exit dropping you out of the shell.
Finally, sure you can automate more & more . but you risk breaking things,
missing errors, etc.
Enjoy!
if [ -z "$1" ]; then
echo ""
echo "Usage:"

echo " prep package-archive"
echo ""
exit 1

if [ -f $1 ]; then
echo "Processing $1"
if [ "${1##*.}" = "gz" ]
then
tar xfvz $1
dir=`basename $1 .tar.gz`
if [ -d $dir ]; then
cd $dir
else
echo "...oops, $dir doesn't seem to exist..."
fi
elif [ "${1##*.}" = "bz2" ]
then
tar xfvj $1
dir=`basename $1 .tar.bz2`
if [ -d $dir ]; then
cd $dir
else
echo "...oops, $dir doesn't seem to exist..."
fi

echo "...oops, $1 doesn't look like an archive..."
fi
echo "Ready!"
else
echo "Error: $1 not found"
exit 1
