Sticky bit

[JEMF <jemf@gabcmt.eb.mil.br>]

Hello all,

Many people says that the stick bit is a feature to keep an executable 
in the memory.

#echo #!/bin.bash > test.sh
#echo echo ok >> test.sh
#chmod 1777 test.sh

#./test.sh
ok

#echo echo ok2 >> test.sh

#./test.sh
ok
ok2

the result with sticky would have to be "ok". Can anybody explain me 
what it happened?

Thanks!
