[oclug] filename renaming

[Woogie]

Using this bit of bash and sed worked for me. It might choke on funky
characters, though

I used "Pictures" as my example directory:

for x in `ls Pictures/*` ; do
DIR_NAME=$(echo $x | sed -e 's|\([^/]*\)/.*|\1|')
FILE_NAME=$(echo $x | sed -e 's|[^/]*/\(.*\)|\1')
echo "${DIR_NAME}_${FILE_NAME}"
done

The first line iterates over all the file names in "Pictures" in the
form "Pictures/filename.jpg"
The second line uses sed to assign the variable DIR_NAME the name of
the directory
The third line uses sed to assign the variable FILE_NAME the name of the file
The fourth line just echoes the form of the filename you wanted. You'd
replace this line with a cp or mv, at your leisure. Remember, $x holds
the path to the file
The fifth line terminates the loop

This is quick and dirty; odds are there are programs out there you
could chain together to get the same results without resorting to
using sed.
