Deletes empty directories and prints an error if directory is not empty.
Change ~/tmp to the destination directory, such as your mounted media. Change -n20 to whatever number of files to copy. It should quit when media is full. I use this to put my most recently downloaded podcasts onto my phone.
find largest file in /var
This works on my ubuntu/debian machines.
I suspect other distros need some tweaking of sort and cut.
I am sure someone could provide a shorter/faster version.
I use this simple command for remove all backup files generated usually by editors like Vim and Emacs.
Find all corrupted jpeg in the current directory, find a file with the same name in a source directory hierarchy and copy it over the corrupted jpeg file.
Convenient to run on a large bunch of jpeg files copied from an unsure medium.
Needs the jpeginfo tool, found in the jpeginfo package (on debian at least).
I have a bash alias for this command line and find it useful for searching C code for error messages.
The -H tells grep to print the filename. you can omit the -i to match the case exactly or keep the -i for case-insensitive matching.
This find command find all .c and .h files
This command looks for a single file named emails.txt which is located somewhere in my home directory and cd to that directory. This command is especially helpful when the file is burried deep in the directory structure. I tested it against the bash shells in Xubuntu 8.10 and Mac OS X Leopard 10.5.6
Clone linux installation.
Copy every file from current directory to destination preserving modification time.

Have a grudge against someone on your network? Do a "find -writable" in their directory and see what you can vandalize! But seriously, this is really useful to check the files in your own home directory to make sure they can't inadvertently be changed by someone else's wayward script.
This example uses the -exec option to move all matching files into a backup directory
Note that this will not work with files with spaces or characters that need to be escaped. Feel free to leave any comments to improve upon this command, and I'll add it in.
