Hi there,

I need counter in a single file for all connections to port 1352. How I can make an acumulative counter?

netstat -n |grep 1352 -c >users_notes.txt this sentence only save one value, and when I execute again the value is overwritte with the new value

Thanks a lot

hi,


if you just want to write the value to the new file without deleting the existing values
you use append as follows

netstat -n |grep 1352 -c >>users_notes.txt

now if you wanna add the new value to the value existiing in the file then you need a script a little bit more involved(if that is the case we can provide a small script for that).

but im afraid your command does not count exactly the number of connections. maybe the next one would be a bit more precise.

netstat -n |grep 1352 | grep -i connected -c >>users_notes.txt
