Shell Programming and Scripting

Hi All,

Can you please help me.

The situation is like this. There are many different file name in this directory.
I have to grep all the file that the name start with "PTWO" and rename it to COM with the current date.

This is the script that I have done and it hit an error..
#!/bin/bash

DAY=`/bin/date +%Y%m%d`

for hs in `ls $target/FTPUSERs/$hh`; do


`grep -i ^PTWO $target/FTPUSERs/$hh/`

`mv $hs COM$DAY.txt`

done

Hope u can help me...

here is a basic code to rename multiple files having common name . You have to modify it as per your requirement

===============
for filename in *;
do
newname=`echo $filename | sed -e 's/oldname/newname/g'`
mv $filename $newname
done
===============

Thanks amitranjansahu,

But my biggest problem right now is how to grep all the filename that start with PTWO and change them to the same new name. There are also other filename in the directory.

Code:

for file in PTWO/*
do
mv "$file" "COM$(date + "%Y%m%d").txt"
done

Thanks devtakh,

But I think u have misunderstand my problem.

PTWO is not the folder name. It is a file name.

Let me clear the situation to you. In folder A there are many different files with different names.
I need to grep all the files in that folder which the name start with "PTWO" and rename them to "COM" with the current date.

Thanks for your help~

Code:

for file in `ls PTWO* 2>/dev/null` # from folder A
do
mv "$file" "COM$(date + "%Y%m%d").txt"
done

devtakh,

I don't think you want to do that, it moves all the selected files to 1 file.

badbunny9316,

Better is to give some examples of the file names and the desired names.
