Adding up individual filesizes in a youtube playlist to get total filesize value-CodePudding

I can get the filesizes of each file in a youtube playlist but how can I add all the individual filesizes together to get a total size in Megabytes or Gigabytes of all of them added together?

Example: Linux / Ubuntu commands

youtube-dl --get-filename -o "File size for %(id)s (%(format_id)s): %(filesize)s = 125*%(duration)s*%(tbr)s" -f "22/best" --ignore-config  "https://www.youtube.com/watch?v=b26ZBgspv7M&list=PLLYQF5WvJdJXE-aP7oF5ucXcCfHmub34A" | (IFS='='; while read -r a b; do echo "$a = $(echo "$b" | bc)"; done)

File size for b26ZBgspv7M (22): NA  = 632016.000
File size for nPr3qtZ5FVE (18): NA  = 47577837.000
File size for 8FCsS6s1Z0k (18): NA  = 67788616.500
File size for TZANoOWFX1M (18): 62402644  = 62393587.750
File size for XA5eobevGv8 (22): NA  = 117960449.500
File size for lDplUpPoCcI (22): NA  = 175676293.75
File size for a7TUIkn3qjY (22): NA  = 299391049.125
File size for HFPObieGamg (22): NA  = 270756696.875
File size for PiiDs8dzSXk (22): NA  = 55946363.250
File size for tth0p7nK18A (22): NA  = 31281180.00
File size for Z_xj9ZTV8ak (22): NA  = 126366879.000
File size for Y_YHqM5nTHA (22): NA  = 42328527.000
File size for BjV-fRCPgAM (22): NA  = 42225633.375

You aready seem to know how to split input - just sum it then.

youtube-dl ..... | (
   sum=0
   while IFS='=' read -r a b; do
       sum=$(echo "$sum   $b" | bc)
   done
   echo "The sum: $sum"
)

Interest yourself in awk, it's a real handy tool. You can search "how to sum column in awk" for sure you'll get ton of examples.

You've almost done it:

youtube-dl ...args...  |
{ while IFS='=' read -r a b; do printf '%s   ' "$b"; done; echo 0; }  | bc
