Ah, you don't seem to have error detection in your script.
After many of your actions, you could put
|| (echo "'action' failed."; exit 1)
For example:
tar -jxf ../mpfr-2.4.2.tar.bz2 >>$Logs || \
(echo "Extracting mpfr failed."; exit 1)
mv -v mpfr-2.4.2 mpfr | source $Msg || \
(echo "Renaming mpfr failed."; exit 1)
Also 'man bash' and read up on the 'trap' built-in. You can do something like:
trap "echo \"'action' failed!\"; exit 1" ERR; action-to-take; trap "" ERR
For example:
trap "echo \"Extracting mpfr failed.\"; exit 1" ERR
tar -jxf ../mpfr-2.4.2.tar.bz2 >>$Logs
trap "echo \"Renaming mpfr failed.\"; exit 1" ERR
mv -v mpfr-2.4.2 mpfr | source $Msg
trap "" ERR
You might have to change the script to use bash instead of sh.
Cleverly crafted, you should be able to catch most of the errors when they
happen while maintaining a readable script.
