Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Print info about your real user.
To get your effective user: whoami

Limit the cpu usage of a process
Similar to `cpulimit`, although `prlimit` can be found shipped with recent util-linux. Example: limit CPU consumption to 10% for a math problem which ordinarily takes up 100% CPU: Before: $ bc -l

delete multiple files from git index that have already been deleted from disk
delete multiple files from git index that have already been deleted from disk. this is pretty terrible, I'm looking for a better way. (much better!! http://www.commandlinefu.com/commands/view/1246/git-remove-files-which-have-been-deleted)

Rips CDs (Playstation, etc.) and names the files the same as the volume name

SSH to a machine's internet address if it is not present on your local network
Ping machine once, waiting 1 second for response until failing. Upon fail, ssh globally, otherwise ssh locally.

Paged, colored svn diff
I put this in a shell script called "svndiff", as it provides a handy decorated "svn diff" output that is colored (which you can't see here) and paged. The -r is required so less doesn't mangle the color codes.

find out how much space are occuipied by files smaller than 1024K
The command gives size of all files smaller than 1024k, this information, together with disk usage, can help determin file system parameter (e.g. block size) or storage device (e.g. SSD v.s. HDD). Note if you use awk instead of "cut| dc", you easily breach maximum allowed number of records in awk.

Count number of files in subdirectories
For each directory from the current one, list the counts of files in each of these directories. Change the -maxdepth to drill down further through directories.
