Can we find some of size of all files in a directry where file names start with an letter t*

the out put of ls -ls t* is

4 -rw-r--r-- 1 root system 61 Jul 03 10:56 t
4 -rw-r--r-- 1 root system 3146 Jul 19 11:11 t1
4 -rw-r--r-- 1 root system 3169 Jul 19 11:11 t2
4 -rw-r--r-- 1 root system 80 Jun 29 10:59 td
4 -rw-r--r-x 1 root system 206 Jul 13 07:25 te
16 -rw-r--r-x 1 root system 15670 Jul 19 15:19 tem
4 -rw-r--r-- 1 root system 13 Jul 25 10:42 temp
4 -rw-r--r-x 1 root system 694 Jul 18 12:12 temp.awk
0 -rw-r--r-- 1 root system 0 Jul 20 13:18 temp3365
4 -rw-r--r-- 1 root system 1313 Jul 18 11:07 tmp

32 -rw-r--r-- 1 root system 30795 Jul 05 16:26 ts_lst


i want the sum of size of all the files..

Code:

ls -ls t* | awk '{sum = sum + $6} END {print sum}'

In bytes

Code:

$ ls -l | awk '$NF ~ /^t/ {c+=$5} END {print c}'

Cheers
