mmmm I know, but it happens.

OK, my fault, sorry, EXITING is called from other function, this is the problem.

the "for" loop call "CHECKING" and then call "EXITING" , but only break the "for" loop, and get the same behavior, show me "OK" echo.

(*this is a sample to show the concept)



test.sh
Code:
#!/sbin/sh

CHECKING()
{
	EXITING 0
}



EXITING()
{
        exit 0      
} 



for i in ls ;do
  ls *.tar* | while read i;do
      echo "Hello"
      CHECKING
  done
done

echo "OK"



sh -x test.sh
Code:
/emmc # sh -x test.sh
+ sh -x test.sh
+ read i
+ ls Backup.tar p7zip.tar.bz2
+ echo Hello
Hello
+ CHECKING
+ EXITING 0
+ exit 0
+ echo OK
OK


I use "#!/sbin/sh" because my script in some point makes a /system format and need the busybox integrated in the recovery, not the included in /system. And /sbin/sh is the standard path to launch the shell from recovery.
