kill process by name
Or even easier, if it's available: $ killall firefox I have no idea why you would want to rely on two unusual dependencies to do something that can be done a hundred ways from coreutils...

Flush DNS cache in MacOS 10.5

Create tar over SSH
Really useful when out of space in your current machine. You can ran this also with cat for example: $ tar zcvf - /folder/ | ssh root@192.168.0.1 "cat > /dest/folder/file.tar.gz" Or even run other command's: $ tcpdump | ssh root@10.0.0.1 "cat > /tmp/tcpdump.log"

dd with progress bar and statistics
This command utilizes 'pv' to show dd's progress. Notes on use with dd: -- dd block size (bs=...) is a widely debated command-line switch and should usually be between 1024 and 4096. You won't see much performance improvements beyond 4096, but regardless of the block size, dd will transfer every bit of data. -- pv's switch, '-s' should be as close to the size of the data source as possible. -- dd's out file, 'of=...' can be anything as the data within that file are the same regardless of the filename / extension.

Display formatted routes

quick copy
Utilizes shell expansion of {} to give the original filename and a new filename as arguments to `cp`. Can easily be extended to make multiple copies.
