script question...

[UltraMaroon]

I want to make a bash script with the line "echo 1 >/proc/sys/net/ipv4/icmp_echo_ignore_all" but if I did that wouldn't it just output "1 >/proc/sys/net/ipv4/icmp_echo_ignore_all"? how do I make it so it reads the command as a command and not a string to be displayed?

Try something like this:

#!/bin/bash
/proc/sys/net/ipv4/icmp_echo_ignore_all

Make sure that you make the script executable with "chmod 755 script_name.sh". It should work.

Well, the hash-bang at the top of the script should refer to /bin/sh, not bash -- there's no point making it less portable for no benefit.

You'd also need echo - /proc/ files are not meant to be executed. So the script would be this:


#!/bin/sh
echo 1 > /proc/foo/bar/baz


Change the /proc line to whatever setting you want to change.
