When I run the ps command i get a warning saying Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQ.How do i suppress this warning? Is there some system setting that i must do for this. The command that I fire is:[root@localhost home]# ps -aux | grep curl -s -o Test Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.7/FAQroot      4856  0.0  0.0   4044   672 pts/0    S+   07:20   0:00 grep curl -s -o Test[root@localhost home]# Note that I have to fire the exact same command as above(I cannot change the -aux to aux, I cannot redirect STDERR output). That is why i am looking for some system setting that will suppress the warning.
