What tool makes you most productitive?
natch: Knowing well how to do for loops on the command line of whatever shell I'm using at the time.Saving snippets of how I get things done.Always saving command lines in shell scripts, sometimes with parameters, instead of just trying to remember them. Bash history is great, but it isn't available when changing systems, hosts, and jobs.Always making a sandbox directory for every idea/project, under a directory named for the current year. This includes my own ideas as well as stuff other people did that I download to play with. When a new year rolls around, most of the directories don't get carried over; they just stay in the old year archived.Tagging every new project with keywords.Automating everything possible.Most fantastic win ever: VMware images that are preconfigured to whatever state they need to be in to debug whatever I'm working on. Could be Amazon AMIs; I use VMware atm.emacs, vi, sort, uniq, comm, find, ack, diff, patch, perl, perltidy, man, git
