Mass file rename from data in a CSV

[Zugdud]

Greetings all, I was wondering if it would be possible to rename a bunch of files based on information from a CSV? For example, here is some data from the CSV:

Oldname Newname
file1 file1_a
file2 file2_b
file3 file3_c
file4 file4_c

Is it possible to rename a directory of files from the old name to the newname in the CSV? Any ideas on what direction I should take or if its possible without major programming?

Thankyou for any insite

Sorry, the actual CSV looks like this , not tabulated columns:

file1,file1_a;
file2,file2_b;
file3,file3_c;
file4,file4_c;

[tt]
awk '
BEGIN { FS = ",|;" }
3==NF {
cmd = "mv " $1 " " $2
system( cmd )
}' /path/to/input
[/tt]

Hi:

Assuming:

file1,file1_a;
file2,file2_b;
file3,file3_c;
file4,file4_c;

is in mydata.file:

#!/bin/ksh

# no error checking
while IFS=",;" read col1 col2
do
mv $col1 $col2
done < mydata.file
