I wrote this a few years back for LinuxQuestions.org. It was around 2004 from memory, and majority of the mail servers in Internet land only allowed for 2MB file attachments. This has now change, but I thought I’d post the article anyway.
There always comes a time, where you wish that file was only a few kilobytes/megabytes smaller. Whether it be so it can fit onto your floppy disk, CD-R etc, or so you can meet the attachment limit on an e-mail server. This isn’t really a command that you would use everyday, but it might come in handy.
A few months ago at work, I needed to send a number of files to a little over 100 Windows workstations. I had administrator rights on all these workstations, and luckily for me, they all had the same administrator password.
I had access to a Red Hat AS4 server, so I wrote a shell script to read all the hostnames of the workstations from a text file, mount each C$ share via CIFS, copy the necessary files, unmount and repeat.
We all download TV shows, there is no use denying it. I recently got pointed in the directory of a rather funny show called The Big Bang Theory. I grabbed the first episode of season 1, saw what I liked, then grabbed the entire season 1 pack.
17 episodes, each in their own folder in .rar files.
What a pain in the ass!
