i write a file name usertest as follows,
#!/bin/sh
cnt=`ps -elf | grep usertest | grep -v grep | wc -l`
echo $cnt
every time i run it, the number it shows bigger that 2.
but if i change the file into
#!/bin/sh
ps -elf | grep usertest | grep -v grep | wc -l
it just show ONE line.
i try the same process in IRIX, it works well. i do not know why!!!
