Renaming Filenames by replacing a part

Shell Programming and Scripting
1

Hi,

I have little experience on Shell scripts, I searched the forum but couldn't make out what I want.

I want to rename a set of files to a new file name

a_b_20100101
c_d_20100101
.......................
......................

I want to rename the files to
a_b_20140101
c_d_20140101

Could you please help to achieve this?

I have a set of 2000 files

if rename works then

rename _2010 _2014 *2010*
3

with sed,

ls *2010* | sed 's/\(.*\)_\([0-9]\{4\}\)\(.*\)/mv \1_\2\3 \1_2014\3/g'

Edit : This will print the mv oldfile newfile to the screen. You can redirect it to a file, take a look and if all ok, source the file with

. command_file

An approach using shell builtins:

for file in *_2010*
do
        mv "$file" "${file/_2010/_2014}"
done

Another way:

ls *_2010*| sed -e "p;s/_2010/_2014/"|xargs -n2 mv
