Nice tip

After accidentally rebooting the wrong server a couple times, forgetting what I had ssh’ed to, I decided on a handy fix, this /usr/local/bin/confirm script:

#!/bin/sh
echo "You are about to run the command '$*' on `hostname`." >&2
echo -n "Are you sure this is what you want to do? (Y/N): [N] " >&2
read x || exit
case "$x" in
[Yy]*)  exec "$@" ;;
*)      echo "Command '$*' aborted." >&2  ; exit 1 ;;
esac

Now, on my servers I add these aliases to root’s .bashrc file:

alias halt=’confirm halt’; alias reboot=’confirm reboot’

That’s saved me a few times since then. The .bashrc file also already had the “alias rm=’rm -i’” in there, which at first I hated, but learned to like it after it too saved my skin on more than one occasion.

Fix log4j.dtd warning in eclipse

The file cannot be validated as the XML definition "/home/drsm/work/workspace/sts2/kgdnp/src/main/java/log4j.dtd (No such file or directory)" that is specified as describing the syntax of the file cannot be located.

you can fix this by manually adding new XML catalog entry to STS. Open the preferences and navigate XML -> XML Catalog and click add to the following entry:

Location: jar:file:/home/drsm/devtools/sts/sts-2.5.0.M3/plugins/org.apache.log4j_1.2.15.v201005080500.jar!/org/apache/log4j/xml/log4j.dtd
(you need to modify this to reflect your installation path)
Key Type: Public ID
Key: -//APACHE//DTD LOG4J 1.2//EN

Now click OK and if everything goes well you see the new entry the User Specified Entries with no red cross indicating an issue.
