You need to have a script that deletes all files in a directory older than 7 days well Linux makes this easy:
Assume the directory we want to use is /local/backup
find /local/backup -mtime +7 -type f -exec rm -f {} \;
and your done.
Change permissions or owner on all files Linux
So you have a directory and you want to change permissions on all files in the directory or directories but not the directories themselve it’s easy in linux
Assume the directory I want to start on is /local and I want everything under this directory to be chmod 644 then I would run
find /local -type f -exec chmod 644 {} \;
Or if I wanted to print out results first to check them
find /local -type f -print
Or if I wanted to change the owner to bob:bob
find /local -type f -exec chown bob:bob {} \;
How about you want to change directories only to 755?
find /local -type d -exec chmod 755 {} \;
Apache count number of hits per ip in your logs
Have you ever wanted to know if a specific ip address is hitting your web server too much?
It’s simple assuming your logs are in /var/log/httpd (redhat) do the following
cat access_log | awk ‘{print $1}’ | sort | uniq -c
It will output a list like this:
4 127.0.0.1
97 192.168.10.30
100 192.168.10.48
288 192.168.10.49
1 192.168.10.51
19 192.168.10.52
199 192.168.10.53
Apache Count number of unique ip’s
So you want to know how many different ip’s have been hitting your apache server?
It’s simple to do first locate your logs normally in /var/log/httpd/access_log (redhat)
Look at the log and identify which field is the ip address in ours it’s the first entry so we will use $1 (if it’s the second replace with $2)
cat /var/log/httpd/access_log | awk ‘{print $1}’ | sort | uniq | wc -l
This will output a count of unique hits. You can also get a list with:
cat /var/log/httpd/access_log | awk ‘{print $1}’ | sort | uniq
