Week of unix tools!
Posted Fri, 18 May 2007
So, I thought I might spend the next 7 days covering some of the tools I find myself working with almost every day. I hope to cover all the ways I use a given tool, when it should be used over any alternatives, things to look up in the manpage, etc.
I'll try to cover more than one tool per day, because some tools can be batched together because there isn't much to day other than "this is useful for foo, bar, anz baz".
Tentative, incomplete list:
- data sources
- cat, GET, echo, nc (netcat), shell command substitution
- cut, grep, paste, sed, sort, tr, uniq, wc
- xargs, sh, awk, perl (for oneliners)
'sort' can sort lines, right? But how do you sort words on the same line?
% echo "one two three four five" \ | xargs -n1 | sort | xargs five four one three twoSome of you might notice that the xargs(1) invocations can be replaced with tr(1). Yes. I use xargs(1) because it's less typing and handles many case tr(1) won't. This is not to say tr(1) doesn't have it's wonderful uses. More on that later this week ;)
If you have suggestions, let me know.
