Renaming multiple files.

Joakim Brosten — Wed, 19 Dec 2007 15:22:38 GMT

Hi,

I've about 1000 files named abc-100.200.def, abc-100.300.def, and so on...

I'd like them called abc-100200.def, abc-100300.def, etc instead. (The first "." deleted)

Do you know a nice way of doing this by one (or two) commands instead of 1000... ?

/Joakim

Shalom,

How about a single while loop.

make a file list, call it list

while read -r filename
do
mv $filename $filenamenew
done < list

Do you have any commands in your mind? You could put those commands into a script & execute the script.

Better still, you can also get a prepared script (utility) to do the job for you. krename is one of them.

Hope this helps.

for FILE in `ls abc*`
do
NEWNAME=`echo $FILE|awk -F "." '{ print $1$2"."$3}'
mv $FILE $NEWNAME
done

Well, this is the bash way:

for FILE in *.*.def
do
mv $FILE ${FILE/\./}
done

This uses bash's inbuilt parameter expansion stuff. This one does a replace on the first regex match. It matches the first '.', and replaces it with ''.
