UNIX for Advanced & Expert Users

I have a.txt and b.txt (and so on ) in a directory.

I need to move these files to a.xml , b.xml and so on, basically I just need to rename all the XXX.txt files to XXX.xml using find and mv , how can we do it?
something like below, but it is not right
find . -name '*.txt' -exec mv {}\.xml \;
Any ideas?

Thanks

If you have the mmv command, you can just do

Code:

mmv '[ab].txt' '#1.xml'

Find won't do exactly what you want, it can't return PART of a filename. You'd have to just leave it printing the output, piping the names into some other script that filters the names.

Thanks for your reply, unfortunately SunOs 5.7 doesn't seem to have mmv.

is there any way we could achieve this by following pseudo

find
mv [the file given by find to] ["work on the result of find to cut just the file name without extension" and add our extension (ie .xml)]

instead using cut and appening the .xml, could we use sed to replace extension to .xml and move the original file to this name?

I am sorry if this is not achievable.

Thanks

Code:

#!/bin/ksh
find /path -name '*.txt' | \
while read file
do
    newfile=${file%.txt}".xml"
    mv $file $newfile
done

I think Sun usually has ksh available

You can use something like this:

#!/bin/sh

for vo in *.txt
do
ao=`echo $vo | sed "s/\..*$//"`
mv "$vo" "$ao".xml
done

Thanks for the reply, both the above suggestions works.

Can we do it in a single line using something like this

for file in `ls *.txt` ;do mv $file `sed 's/\..*$/.txt/'`;done

this doesn;t work, but I feel that this may work with minor tweaks.

Thanks again for the reply!

Code:

find /path -name '*.txt' | while read file ;do ; newfile=${file%.txt}".xml" ; mv $file $newfile ; done

why one line - it's harder to read....
