I have some files I want to rename them upon parts of their names .
For example : files :
part03_iti_r01_ch03_ver03_conditional_statements_o ne_if_TV_Rental_bills.c
part03_iti_r01_ch03_ver04_conditional_statements_o ne_if_else_TV_Rental_bills.c
part03_iti_r01_ch03_ver05_conditional_statements_m ulti_if_else_TV_Rental_bills.c
part03_iti_r01_ch03_ver06_conditional_statements_s witch_TV_Rental_bills.c


I want to issue unix2dos command for each file :
as:


unix2dos part03_iti_r01_ch03_ver03_conditional_statements_o ne_if_TV_Rental_bills.c
ex0303.c
I will convert
part03_iti_r01_ch03_ver03_conditional_statements_o ne_if_TV_Rental_bills.c
I chose ex^^ & ^^.c

Which utility I can choose for accomplishing thar task ?
sed,Perl.... How can I use it in a loop?

Hint:
sed 's/.*_ch\([0-9][0-9]\)_ver\([0-9][0-9]\).*/ex\1\2/'

while IFS='_' read part iti r ch ver rest; do
echo $ch $ver
echo ${ch#ch} ${ver#ver}
done

If your filenames are *really* that regular, then you may use
something like

# ls *.c
[snip list as above]

# perl -e '$"=""; rename $_, "ex@{[(/\d+/g)[2,3]]}.c" for @ARGV' *.c
# ls *.c
ex0303.c ex0304.c ex0305.c ex0306.c

you'll see that it shouldn't be so. AND, the writting as usuall is
fantastic incompetent. To illustrate, i quote:
