Hi all,
I'm having a problem with a simple script i'm trying to create.
I have created a file that has this form:
| Code: |
2 xx.xxx.xxx.xx
1 xxx.xxx.xxx.xx
1 xxx.xxx.xxx.xx
|
*the ips have been replaced with 'x'
Now i want to detect if any number from the first column is above a certain limit.
The problem is that when i use awk to check the first argument in the line it can't be recognised.This is where i need some help.
After the detection i'll do some actions with the ip that refers to the number that has been detected to be higher than the limit.
thanks.

Here is what i want to do.
The file is created using the netstat command.The problem is that i want to compare only the first column with the variable limit.
| Code: |
#!/bin/bash -x
limit=4
netstat -tanp | grep \:80 | awk '{print $5}' | cut -f 1 -d: | sort | uniq -c | sort -nr | head -n 20 > test;
chmod +x test
for i in `cat /home/...../test`
do
if [ $limit -lt $i ] then
echo found
fi
done

I have modified your script.
| Code: |
#!/bin/bash -x
limit=4
netstat -tanp | grep ':80' | awk '{print $5}' | cut -d: -f1 | sort | \
uniq -c | sort -nr | head -n 20 >/tmp/test$$
chmod +x /tmp/test$$
for i in `cat /tmp/test$$`; do
if [ $limit -lt $i ]; then
echo found
fi
done

Thanks for the modification.
The problem is that something is wrong with i.
If you try this
| Quote: |
netstat -tanp | grep ':80' | awk '{print $5}' | cut -d: -f1 | sort | \
uniq -c |sort -nr | head -n 20 | awk '{print $1}' |
the first column will be printed.However if i try to check each $i ,something is wrong.
