rename bulk files

Hello

I have bulk files like:

prd1_w1p1_0000009319_1_200906270750
prd1_w1p1_0000009320_1_200906270750
prd1_w1p1_0000009321_1_200906270750
...
...
....

I want to rename them to

w1p1_0000009319_1.arc
w1p1_0000009320_1.arc
..
..
..

What is the best technique to perform this action?
I want to learn rather than copying pasting the script.
HP unix.

Thanks in advance

I have to use it in for loop to rename these files as I want.
However I am little bit confused.

Code:

awk 'BEGIN{FS="_"}

{

 m=split(FILENAME,file,"_")

 newfile = file[2] FS file[3] FS file[4]".arc"

 cmd="mv "FILENAME" "newfile

 system(cmd)

 nextfile

}' prd*

of if you don't mind a ready script (python), see my sig last link called File renamer

Code:

# filerenamer.py -p "prd1_(.*?)_\d+$" -e "\1.arc" -l "*"

==>>>>  [ /home/prd1_w1p1_0000009320_1_200906270750 ]==>[ /home/w1p1_0000009320_1.arc ]

==>>>>  [ /home/prd1_w1p1_0000009319_1_200906270750 ]==>[ /home/w1p1_0000009319_1.arc ]

==>>>>  [ /home/prd1_w1p1_0000009321_1_200906270750 ]==>[ /home/w1p1_0000009321_1.arc ]

remove -l option to commit changes

Your ready script is little bit complicated,hard to understand :)
I tried your first suggestion:
After I run the script, it modified first file (2466) and then it gives error like:
It didnt modified the rest of the files.It only modified one file

mv: prd1_w1p1_0000002466_1_200906170433: cannot access: No such file or directory
mv: prd1_w1p1_0000002466_1_200906170433: cannot access: No such file or directory
mv: prd1_w1p1_0000002466_1_200906170433: cannot access: No such file or directory
mv: prd1_w1p1_0000002466_1_200906170433: cannot access: No such file or directory
..

How about

Code:

for i in prd1* ; do mv $i `echo $i | sed 's/.*prd1_w1p1_$.*$_1_.*/w1p1_\1\.arc/'` ; done

and you understand that sed statement??anyway, you can use bash without external tools

Code:

for i in prd1* 

do

    newname=${i/prd1_/}

    newname=${newname%_*}".arc"

    echo "mv $i $newname "

done

you don't have to understand the inside of the script. Just run it like i showed you.

i edited the awk script to include nextfile statement. it should work now.

If you want to understand the sed statement, have a look at http://www.ibm.com/developerworks/li...ry/l-sed1.html

The use of $.*$ is covered on page 2.
