Details:
I searched and did not find related fix/bug
script ff
find . -type f \( -name "*\.[cC]" -o -name "*\.[hH]" -o -name
"*\.[cC][pP][pP]" \) | xargs -I"{}" grep -Hn $1 $2 $3 $4 $5 $6 $7 $8 $9 "{}"
script ff0
find . -type f \( -name "*\.[cC]" -o -name "*\.[hH]" -o -name
"*\.[cC][pP][pP]" \) | xargs -P0 -I"{}" grep -Hn $1 $2 $3 $4 $5 $6 $7 $8 $9
"{}"
cd to kernel source /usr/src/linux
and run the scripts as
ff -w long > /dev/shm/1
and
ff0 -w long > /dev/shm/0
The result is different and the line in /dev/shm/0 are mangled and the file
size is smaller.
