I want to get the total count of the number of lines from all the files returned by the following command:

shell> find . -name *.info

All the .info files are nested in sub-directories so I can't simply do:

shell> wc -l *.info

Am sure this should be in any bash users repertoire, but am stuck!

Thanks

You can use xargs like so:

find . -name *.info -print0 | xargs -0 cat | wc -l

    Don't forget to quote your shell meta-characters or else you might wonder why you're getting odd results or odd errors from find: find . -name '*.info' -print0 | xargs -0 cat | wc -l – Adrian Pronk Aug 04 '10 at 11:36

wc -l `find . -name *.info`

If you just want the total, use

wc -l `find . -name *.info` | tail -1

Edit: Piping to xargs also works, and hopefully can avoid the 'command line too long'.

find . -name *.info | xargs wc -l

some googling turns up 

find /topleveldirectory/ -type f -exec wc -l {} \; | awk '{total += $1} END{print total}'

which seems to do the trick

       s=$(wc -l< "$file")
       sum=$((sum+s))
   fi

echo "Total: $sum"

find . -name "*.info" -exec wc -l {} \;

Note to self - read the question

find . -name "*.info" -exec cat {} \; | wc -l
