This has helped me numerous times trying to find either log files or tmp files that get created after execution of a command. And really eye opening as to how active a given process really is. Play around with -anewer, -cnewer & -newerXY
xargs can be used in this manner to download multiple files at a time, and xargs will in this case run 10 processes at a time and initiate a new one when the number running falls below 10.
dsh - Distributed shell, or dancer?s shell ;-)
you can put your servers into /etc/dsh/machines.list than you don't have to serperate them by commata or group them in different files and only run commands for this groups
dsh -M -c -a -- "apt-get update"
Same as:
1 rpm -ivh package.rpm
2 yum localinstall package.rpm
3 Edit /etc/yum.conf or repository.repo and change the value of gpgcheck from 1 to 0 (!dangerous)
for mousevents, move the mouse over the window and click/move etc.
usefull for getting mouseKeys, or keyKeys. also usefull for checking if X gets those mouse-events.
If the site uses https, use:
wget --reject html,htm --accept pdf,zip -rl1 --no-check-certificate https-url
to convert a whole directory, put all mp3 files in a for loop
for i in $(ls *mp3); do mpg123 -s $i | faac -b 80 -P -X -w -o ${i%mp3}m4b -; done
rkhunter (Rootkit Hunter) is a Unix-based tool that scans for rootkits, backdoors and possible local exploits. rkhunter is a shell script which carries out various checks on the local system to try and detect known rootkits and malware. It also performs checks to see if commands have been modified, if the system startup files have been modified, and various checks on the network interfaces, including checks for listening applications.
chkrootkit is a tool to locally check for signs of a rootkit,Get it from the website http://www.chkrootkit.org
grab the weather, with a little expletive fun. replace the 48104 with a US zipcode, or the name of your city (such as ZIP="oslo"), unless you want to know what the weather is like for me (and that's fine too)
To get information at your fingertips about Apache compilation.
Like many other thing in Linux ,you can see the same thing in different way.
This is a handy way to find which modules are loaded with Apache web server.
You can try it . Nice shell interface to search google from the command line.Visit http://goosh.org in your browser.
This command will reveal login has been made to the system as well as when the reboot occurs. It uses a file called /var/log/wtmp,which captures all the information about the successful login and reboot information. It has many switch ,by which you can get an idea when people login how long they stay.
The important thing to note in this command, is the "-n" flag.
