How to rename all files at a time by appending some characters at the begining?

Hi

I have a list a filename in a directory starting with particular pattern
for example:

Code:

abc_1234.txt
abc_7565.txt
abc_7676.txt
abc_7765.txt

i need to rename all these files by appending bck. or bck_

Expected output:

Code:

bck.abc_1234.txt
bck.abc_7565.txt
bck.abc_7676.txt
bck.abc_7765.txt

Can anyone suggest something regarding this.
I tried the below code but its not actually working. How to make this permanent.

Code:

ls -1 abc* | awk '{$1="bck."$1; print $1}'

but not getting the expected result.

I am using k-shell

Hiya

Try:

Code:

for f in abc*
do   mv "$f" "${f/abc/bck.abc}"
done

Or even simpler:

Code:

for f in abc*
do   mv "$f" "bck.$f
done
