Hey, It's me again! Still trying to learn to become a better scripter on the job
New challenge for assistance, if anyone cares to help, and its two parted! First part, I wanted to create a script at work that would ping a server that was supplied in an argument, then a count (amount of times) it should be pinged.
I came up with a solution that I thought worked.
Code:
#!/bin/bash
#Written by: Manny
#Date: 9/19/2013
HOST=$1
COUNT=$2
for hosts in $HOST
do
ping=$(ping -c $COUNT $myHost | grep 'received' | awk -F',' '{ print $2 }' | awk '{ print $1 }')
if [ $count -eq #IwantToCheckAgainstHalfofCOUNT ];
then
echo "Host : $hosts is down"
return 1
fi
else return 0
done
I was pretty much told, "No, I want it done a different way" (There is a method to their madness I suppose)
Any-ways, I have some pseudo code of how I interpret how they want it, but cant figure out how to get both Counters to work.
Code:
while COUNT <= number_of_times_i_ask_it_to_ping
if ping -c1 host_i_ask_it_to_ping
PINGCOUNT++
fi
COUNT++
done
So Any Help Making that into something i can use would be greatly appreciated it.
also. if you see my first solution. I have a threshold of 50% of packets lost that i wanted to test that if statement against, but couldn’t think of a way to do that either. so for my own PERSONAL reasons, if anyone can think of a cool way to go about doing that, would be greatly appreciated as well.
Quick Edit: in my pseudo code, i use a while loop, but it doesn't have to be. I'm sitting here playing with for loops like
Code:
for (( count=1; count <= $COUNT; count++ ))
do
ping -c 1 $HOST
done
to see if i can make that work instead.

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
