How to change extension? - Shell Programming and Scripting

Vishnu · #4 (**permalink**) 11-15-2002

replace those "rtf" and "doc" with $1 and $2 in your script...

I should add that the above way using "cut" will not work if you have multiple dots in your filename...

Code:

#!/bin/sh 
for name in `ls *.$1` 
do 
name1=`echo $name | sed -e "s/^\(.*\)\.$1$/\1\.$2/g"` 
mv $name $name1 
done

or a more compact and faster version which I prefer...

Code:

#!/bin/sh 
ls *.$1 | sed -e "s/^\(.*\)\.$1$/\1\.$1 \1\.$2/g" | xargs -n 2 mv -f

Cheers!
