Enable ExecShield protection – ExecShield is security Linux kernel patch to avoid worms and other problems.
After Adding to
/etc/sysctl
kernel.exec-shield = 1
Getting this error sysctl: cannot stat /proc/sys/kernel/exec-shield: No such file or directory
Output :
root@ashishk:/home/ashish/MyScripts# sysctl -p

Can i know what is wrong ?

c4f4t0r already provided an answer to the immediate question in the comments, but it is not entirely accurate.
exec-shield continues to exist; what actually was removed was the option to disable it through the sysctl setting
