Umount only the NFS related to 'string'
Sometimes, you have a lot of NFS in the server and you can't or shouldn't use umount -a. Whis this command, you only umount the fs related to the 'string'

Display a random man page
I'm not sure why you would want to do this, but this seems a lot simpler (easier to understand) than the version someone submitted using awk.

Resize a Terminal Window
Replace 70 with the desired height. Replace 180 with the desired width. I put it in my bashrc, because by default my terminal is too small.

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously

Insert a line for each n lines

start vim in diff mode
vim will open both files side by side and show colored diffs

Compare copies of a file with md5
I had the problem that the Md5 Sum of a file changed after copying it to my external disk. This unhandy command helped me to fix the problem.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Copy via tar pipe while preserving file permissions (cp does not!; run this command with root!)
cp options: -p will preserve the file mode, ownership, and timestamps -r will copy files recursively also, if you want to keep symlinks in addition to the above: use the -a/--archive option
