I have not had a shutdown fail... perhaps someone could help you with this
if you would post an explanation.
You don't say what filesystem type(s) you are using; if you switch to a
journalling filesystem, then your filesystems will always be clean (at the
expense of reduced performance on writes). If you are using ext2, then it
is a simple matter to convert to ext3. When I first considered
converting, I tested ext3 fairly brutally by cutting power in the middle
of writes. I was unable to break it, always came up clean. This is a
personal observation, not any guarantee.
You do not say which shell you are using. If you are using bash, then
there are three files relevant to your question:
~/.bash_profile executed by bash for a login shell.
~/.bashrc - executed by bash for non-login shells.
~/.bash_logout - executed when login shell exits.
As s. keeling replied, "man bash" for further info. There are also a lot
of shell scripting tutorials out there on the web; also, there is a Linux
"Bash Programming - Introduction" HOWTO.
A Happy Christmas to you.
