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

This is the same was %W. %M Normal chat message (white). This will appear as if the user said it. %T Emote chat message (???). This will appear as if the user said it. %W Use the warning attribute (yellow). This is the same was %I. Within a line, any of the following format formatters may be used: %% Expand to a literal percent sign (%). %a Expand to the number of accounts on the server. %c Expand to the number of channels on the server. This includes all permanent and current temporary channels. %g Expand to the number of games on the server. This includes both public and private (passworded) games. %h Expand to the hostname of the server (as returned by gethostname(2)). %i Expand to this user's account ID number, formatted with a leading pound (#) sign and leading zeros. %l Expand to this user's current chat name which is usually the same %r Expand to the IP of the remote machine (the client). %t Expand to four character client tag. %u Expand to the number of users logged into the server. %v Expand to the version number of the server.
