One liner shell command to find and rename to lowercase all SHP, DBF, and SHX file extensions starting from current directory: EXTENSIONS="SHP SHX DBF" for E in $EXTENSIONS ; do export E; export e=`echo $E | tr '[:upper:]' '[:lower:]'`; for f in `find . -name "*.$E"` ; do mv $f `echo $f | sed "s/$E/$e/"`; done ; done Useful when you get your shapefiles over from Windows and mapserver won't cooperate.

Even as good as shell scripting is, sometimes I wish it was easy to keep track of state across script executions, for instance when a script executes a rsync at short intervals. In that case I don't care if one particula rsync fails, but I definitely care if it fails, say, ten times in a row or for more than a day. To do this I need some kind of way to keep state and record each run exit status. The simplest approach that I could think of is to use SQLite . Copied straight from the SQLite site:  SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is the most widely deployed SQL database engine in the world. The source code for SQLite is in the public domain. As I said, in this example I'll show how to track the status of a series of rsync operations, all run from a central node and pushed to remote nodes...
