Hi Bartus,

Is it like if there are 100 files then get 50 files and call function concurrently.

Like this?
Code:
 
function first {
#to_process=$1
cd $1
for i in *.txt
do
echo $i
awk '/<.*/ , /.*<\/.*>/' "$i" | tr -d '\n'
echo -ne '\n' 
done
}
first /home/Folder1 &
first /home/Folder2 &
wait

Please let me know if im wrong.Also is multithreading an option here?

Thanks,
Chetan
