Combination of find -xargs & wc -l

mr_bold · #1 (**permalink**) 07-08-2008

Dear all,

I have to calculate sum of record count of files of the specified directory.
First I tried the following way which prints one or more outputs.
How can I sum of this output?

Code:

find /home/work/tmp/1/O/ -type f -print0 | xargs -0 wc -l | grep total
  1666288 total
  1073908 total

Thanks in advance

If it's just for that directory, you could do a wc -l on those files like

Code:

root@sremhv27:/usr/IBM/HTTPServer/conf/sicher> wc -l *| tail -1| cut -d " " -f1
     916 httpd.conf
     209 ldap.prop.elan
     209 ldap.prop.papyrus
    1334 total

# ie. 

root@sremhv27:/usr/IBM/HTTPServer/conf/sicher> wc -l *| tail -1 |awk '{print $1}'
1334

If you want to have it including files in the subdiretories (which might be the reason you are using find), I would go and just fill an array with it like:

Code:

#!/usr/bin/ksh

typeset -i RESULT=0

set -A ARRAY "`find . -type f -exec wc -l {} \; | awk '{print $1}'`"

for ELE in ${ARRAY[*]}; do
        let RESULT=${RESULT}+${ELE}
done

echo "Result is: ${RESULT}"

This ksh, but if you are using another shell, you can just do ARR=`somecommandtomakealist`; for ELE in $ARR; do something; done
So no extra defining of an array with set -A has to be done. Just wanted to do it correct for ksh.

Assuming no newlines in the filenames:

Code:

(IFS=$'\n'; awk 'END{print NR}' $(find -type f))

If you have zsh:

Code:

awk 'END{print NR}' **/*(.)

Thank you very much,

There aren't any subdirectory.
There are many files so I can't directly use wc or awk.

Code:

wc -l * | tail -1
-bash: /usr/bin/wc: Argument list too long

I can do it by following script in bash.

Code:

sum=0

for eachtotal in `find /home/work/tmp/1/O/ -maxdepth 1 -type f -print0 | xargs -0 wc -l | grep total | awk '{print $1}'`
do
sum=`expr $sum + $eachtotal`
done

echo $sum

Are there some way to do this in one line code, because I am writing bash shell script which consists of hundreds of lines?

Something like this:

Code:

find -type f -exec wc -l {} +|awk '{_+=$1}END{print _}'
