Ah well, I might give the actual full script I am going to use:
Here is the script that changes the filename:
----------------- delparen.sh --------------
#!/bin/bash
if [ $# -lt 1 ]; then
echo "Missing filename. Usage is:";
echo "$0 <filename>";
exit -1;
fi
#get the filename
fn=$1;
#get new filename (following is one long line)
nn2=`echo "$fn" | sed -e
's%\(.*\)\s*(\([0-9]\{3,3\}\))\.[Jj][Pp][Gg]%\\1\2.jpg%'`;
#tell what is being done
echo "$fn --to--> $nn2";
#do the change
mv "$fn" "$nn2";
exit 0
----------------------------------------------
And here is the command that finds all my image files in directory E and
renames them using the above script:
$> find E/ -name "*.[Jj][Pp][Gg]" -exec ./delparen.sh "{}" \;
BTW, for some reason, the following does not work:
$> for f in `find E/ -name "*.[Jj][Pp][Gg]"`; do echo "$f"; done
The output of the above command has a new line before each parenthesis.
