Check These Out

find text in a file
this will find text in the directory you specify and give you line where it appears.

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Display the human-readable sizes of all files and folders in the current directory with 3 decimal places
To sort the list by file/directory size, insert `sort -n |` before `awk`.

Capture video of a linux desktop
This is identical to the original command, but allows you to specify an offset if you have multiple monitors. In this case you'll record a 1366x768 window that's offset by 1366 pixels in the x axis and 0 pixels in the y axis. Note also that the -sameq option has been replaced by -qscale - at least in ffmpeg version 1.2.1 on Fedora 19.

Use Perl like grep
Much better alternatives - grep-alikes using perl regexps. With more options, and nicer outputs.

Blacklist usb storage
Some times you may ban usb to protect thefting of your personal data. Blacklist the usb_storage module by adding blacklist usb_storage to /etc/modprobe.d/blacklist.conf. To load the module manually, $sudo modprobe usb_storage.

Send an email from the terminal when job finishes
Might as well include the status code it exited with so you know right away if it failed or not.

print contents of file from line 1 until we match regex
Start printing the contents of filename to stdout, until a matching line to regex is found, then stop.

Remove a file whose name begins with a dash ( - ) character
Using the redundant ./ directory information prevents the dash from occurring at the beginning of the filename, and being interpreted as an option of the rm command. Also works using: $ rm -- -filename

Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him
