Here's a collection od Unix commands and tools which can be useful when coding, or if you're a sysadmin. I'll add new entries as soon as I am aware of them... it'll be quite useful for me, as I tend to forget commands. :-)
- Ethereal - it's a tool similar to tcpdump, but it offers a GUI and a ton of interesting features.
- wget --convert-link --mirror -E url - mirrors a web site making it locally browseable.
- lsof -p pid - lists the file that a process has open, including the executable and the shared libraries.
- strace -p pid - attachs to an active process and show all system calls being made.
- vmstat 5 - gives top-like information of memory usage, refreshing every 5 seconds.
