bash shell filtering of number
I am capturing ping statistics to a file, and I am trying to sort data by the max ping time to see if its higher than 10 to save that data to another folder, but I am at a loss, here is a sample of my nasty code ;)
# my ping script:
#!/bin/bash
TIMESTAMP="$(date +%Y%m%d%k%M)"
ping -i 2 -s 8000 -c 300 192.168.1.1 > "/var/spool/pingstats/$TIMESTAMP"
#sample of ping data I want to filter (2.332 is the important number):
rtt min/avg/max/mdev = 2.120/2.178/2.332/0.067 ms
# My sort script:
#!/bin/bash
for i in $(grep 'max' /var/spool/pingstats/* |awk ' { print $5}' |cut -d"/" -f3);do
if [ $i -gt 10 ]; then
mv $i /tmp/badpings/
fi
done

I already have that portion working, I guess I am mostly having trouble with the for loop that compares the output of my grep to see if it is -gt 10.
My ping command logs to a single file for 10 minutes, then after 10 minutes it starts a new file, I can manually grep out the data that I want - and it makes a line for each ping file, but i need to loop all that through the -gt comparison to see if the data is above 10 - this part is where i am stuck.

i think you also want to print $4 on your awk statement and bash is not real good with decmil arithmitic
This following line doesn't look right:
Do you want $i to be the line, or the timestamp name of the file. It looks like you are trying to do both.
As written, $i should be the result output. So for the last line, you want to do something like:
Since $i is not a file, but a result, you can't really "move" it.
for i in $(grep 'max' /var/spool/pingstats/* |awk ' { print $5}' |cut -d"/" -f3);do
if [ $i -gt 10 ]; then
mv $i /tmp/badpings/

echo $i >> /tmp/badpings/somefilename
Since $i is not a file, but a result, you can't really "move" it.
Also, $i (if your awk is correct), will only give you a result, not the full line. So your "somefilename" will look like this:
10.234
11.872
55.982
...
And I'm not sure that's what you want. Let me look, and I'll see if I can come up with a basic script.

ping -i 2 -s 8000 -c 300 192.168.1.1 |grep time=[1-9][0-9]
Results:
8008 bytes from 192.168.1.1: icmp_req=1 ttl=63 time=13.4 ms
8008 bytes from 192.168.1.1: icmp_req=2 ttl=63 time=11.4 ms
Now, all you have to do is echo that to a file via >> which you can then name by timestamp. This will give you all times greater than or equal to 10 ms
