tired of opening tabs and fill in search forms by hand? just pipe the search terms you need into this surfraw loop. you can use any browser you have installed, but a graphical browser with a tabbed interface will come in handy. surfraw can be found here: http://surfraw.alioth.debian.org

I liked vaporub's suggestion, here a little simplification of the sed command.

Per country GET report, based on access log. Easy to transform to unique IP Show Sample Output

Given a dump.sql file, extract table1 creation and data commands. table2 is the one following table1 in the dump file. You can also use the same idea to extract several consecutive tables.

Or, if you have restricted access for sftp only, I think you can still do this: diff /path/to/localfile <(scp user@host:/path/to/remotefile >(cat))

Exactly the same effect with 3 less characters ;-) (Removes all files/filesystems of a harddisk. It removes EVERYTHING of your hard disk. Be careful when to select a device.) You can press Ctrl + C after few seconds (No output)

Processes biglion quantity of sold ebay coupons/bonus codes, so you can know approximate count of users who buyed the coupons and when sales are come up again. You can change sleep parameter so script will work slowly or faster (default is 5 seconds). Additional requirements: curl Standart tools used: awk, date, cat, grep (bash) Show Sample Output

Needs to be run in a battery sysfs dir, eg. /sys/class/power_supply/BAT0 on my system. Displays the battery's current charge and the rate per-second at which energy is {dis,}charging. All values are displayed as percentages of "full" charge. The first column is the current charge. The second is the rate of change averaged over the entire lifetime of the command (or since the AC cable was {un,}plugged), and the third column is the rate of change averaged over the last minute (controlled by the C=60 variable passed to awk). The sample output captures a scenario where I ran 'yes' in another terminal to max out a CPU. My battery was at 76% charge and you can see the energy drain starts to rise above 0.01% per-second as the cpu starts working and the fan kicks in etc. While idle it was more like 0.005% per-second. I tried to use this to estimate the remaining battery life/time until fully charged, but found it to be pretty useless... As my battery gets more charged it starts to charge slower, which meant the estimate was always wrong. Not sure if that's common for batteries or not. Show Sample Output

If you don't have telnet, you can use the bash built-in tcp pipes.

You could have that little benchmark run on all cores in parallel, as a multi-core benchmark or stress test First find the number of cores, then have parallel iterate over that in, well, parallel Show Sample Output

Just waste some resources in a philosophical way

Searches /var/log/secure for smtp connections then lists these by number of connections made and hosts.

Adds the stdout (standard output) to the beginning of logfile.txt. Change "command" to whatever command you like, such as 'ls' or 'date', etc. It does this by adding the output to a temporary file, then adding the previous contents of logfile.txt to the temp file, then copying the new contents back to the logfile.txt and removing the temp file.

It's not a big line, and it *may not* work for everybody, I guess it depends on the detail of access_log configuration in your httpd.conf. I use it as a prerotate command for logrotate in httpd section so it executes before access_log rotation, everyday at midnight.

Prints the type of computer you have. I think this should be used more in distros and other applications because it is so easy to get. This can also be asked by tutorials as an easy way to get your base hardware. Some alternatives: sudo dmidecode -s system-product-name and sudo smbios-sys-info-lite | sed -n 's/^Product Name: *\(.*\)/\1/p' Show Sample Output
