I have a bunch of xml files in a directory that need to have the dos2unix command performed on them and new files will be added every so often. I Instead of manually performing dos2unix command on each files everytime I would like to automate it all with a script. I have never even looked at a shell script in my life but so far I have this from what I have read on a few tutorials:
FILES=/tmp/testFiles/*
for f in $FILES
do
fname=`basename $f`
dos2unix *.xml $f $fname
done
However I keep getting the 'usage' output showing up. I think the problem is that I am not assigning the name of the new file correctly (fname).
The reason you're getting a usage message is that dos2unix doesn't take the extra arguments you're supplying. It will, however, accept multiple filenames (also via globs). You don't need a loop unless you're processing more files than can be accepted on the command line.
dos2unix /tmp/testFiles/*.xml
Should be all you need, unless you need recursion:
find /tmp/testFiles -name '*.xml' -exec dos2unix {} +
(for GNU find)
