Script to rename from *.abc to *.def

[Pedro Cirne]

Hi,

I need to rename all *.abc files to the same name but with a diferent extension, let's say *.def, for example:

portugal.abc to portugal.def

Any ideias on how to do this with a script?

Thks,

Pedro

I think this would do it:


for FILE in *.abc
do
mv $FILE `basename $FILE`.def
done

Providing you're just dealing with a single directory of files:

for i in *.abc
do
mv $i `sed -e "s/\.abc/\.def/"`
done

for i in `ls *.abc`
do
mv $i $i.def
done

Correction;

for i in `ls *.abc`
do
newname=`echo $i | awk -F. '{print $1}'`
mv $newname $newname.def
done

#usr/bin/sh

ls | grep -E -e '\.abc$' | while read FNAME
do
BASE=$(basename "${FNAME}" ".abc")
NEW_FNAME="${BASE}.def"
if [[ -e "${NEW_FNAME}" ]]
then
echo "Can't rename ${NEW_FNAME}; file exists." >&2
else
mv "${FNAME}" "${NEW_FNAME}"
fi
done

With a bit more work, you could pass in the old and new suffixes and shell arguments but I'll leave that as a student exercise. Man basename for details.

Oops, had an error in there...
The following:

for i in *.abc
do
mv $i `sed -e "s/\.abc/\.def/"`
done

Should be:
for i in *.abc
do
mv $i `echo ${i}|sed -e "s/\.abc/\.def/"`
done
