Linux shell command questions


Hi all,



1. how can I rename multiple files to SUBTRACT characters from the original name, rather than add, kinda the opposite of what you do with for file.....done command, like:

for file in *.old;
do
mv -v $file ---here I want to rename the file from barbie.txt.old back to barbie.txt
done



2. how can I delete shell variable?

3. in OPENNA when Ctrl+D nothing happens

4. will !ch insert most recent command that started with ch? like if I had chmod 770, will !ch insert chmod 770?


Thanks in advance

I'd use sed s/old.txt/txt (dunno if you need a \ before the . ?) but then I take long winded ways of doing things.

1. Try this command

for F in *.old
do
mv -v "$F" ${F%.old}
done

2. unset <variable>
