Need help in batch renaming files with bash shell script.
I have some 50+ files in the following format :

Code:
abcd_vish_running_ZEBRA_20140818.dat_08-14-2014_23:08:23
abcd_vish_running_ZEB-RA_20140818.dat_08-14-2014_23:08:35
abcd_vish_running_ZEB_RA_20140818.dat_08-14-2014_23:08:37
abcd_vish_running_RI-NG_20140818.dat_08-14-2014_23:08:42
abcd_vish_running_RING_20140818.dat_08-14-2014_23:08:45
abcd_vish_running_RI_NG_20140818.dat_08-14-2014_23:08:52

(ZEBRA,ZEB-RA,ZEB_RA,RI-NG,RING,RI_NG are given to just show the pattern)

i need the to rename the above files to following format :

Code:
abcd_vish_running_ZEBRA_20140818.dat
abcd_vish_running_ZEB-RA_20140818.dat
abcd_vish_running_ZEB_RA_20140818.dat
abcd_vish_running_RI-NG_20140818.dat
abcd_vish_running_RING_20140818.dat
abcd_vish_running_RI_NG_20140818.dat

Now how to achieve this with shell scripting ? I'm fairly new to scripting. Kindly help.

Cheers.

Is this a homework assignment?

What have you tried.

We are doing some kind of a data load. For this we have to copy a set of source files from archival directory through ftp ,then unzip it and have to rename it before starting the data load. This is being done on a daily basis. So I'm trying to automate this process. So far I'm able to FTP download the files and rename them. Now I'm stuck at this step. As I already said I'm new to scripting. So far, whatever I have done is with the help of Google, and forums like this.

Hope this helps.

Cheers.

try this:
Code:
#!/bin/bash

ls *.dat_* | while read line
 do
 part1=$(echo "$line" | cut -d"." -f1)
 mv "$line" "$part1.dat"
 done

edit / another approach:
Code:
rename 's/\.dat_.*/\.dat/' *.dat_*
