| 03:14 | <&McMartin> | I have a sinking feeling that awk is actually the best tool for me to use for this minor task |
| 03:14 | <&McMartin> | But some ancient secrets are best left unplumbed. |
| 03:16 | <&[R]> | $ xxd /dev/urandom | head | cut -d \ -f 2-9 | tr -d \ # Ten random hexidecimal passwords (I use this fairly often) |
| 03:16 | <&[R]> | I could probably replace the cut+tr with awk, but meh |
| 03:17 | <&ToxicFrog> | There are a lot of things that could be replaced with awk but are more clear as a chain of cut, paste, grep, and tr |
| 03:17 | <&McMartin> | I'm looking for a sort/uniq of every call in a C program that starts with a certain prefix. |
| 03:17 | <&McMartin> | For which grep is a decent start, but then I need to do the "extract the capture" and "maybe more than one per line" bits |
| 03:18 | <&ToxicFrog> | "extract the capture" is grep -p |
| 03:18 | <&ToxicFrog> | Er |
| 03:18 | <&ToxicFrog> | grep -o |
| 03:18 | <&McMartin> | Oho! |
| 03:18 | <&ToxicFrog> | And if there's more than one match per line it outputs all of them on separate lines |
| 03:18 | <&McMartin> | A trick I did not previous know |
| 03:18 | <&McMartin> | Even better! |
| 03:19 | <&McMartin> | Yeah, that's just grep -o | sort | uniq then |
| 03:19 | <&McMartin> | cheers |
| 03:19 | <&[R]> | I find that just randomly going through the core-utils man pages every so often is useful if you use them with any regulariy |
| 03:19 | <&[R]> | sort -u |
| 03:19 | <&[R]> | :p |
| 03:20 | | * McMartin stage-whispers, "I don't" |
| 03:20 | <&ToxicFrog> | Or, depending on what you want, | sort |
| 03:20 | <&ToxicFrog> | Or, depending on what you want, | sort | uniq -c | sort -g |
| 03:20 | <&ToxicFrog> | Which will uniqify and then order by number of occurrences. |

| 04:08 | <~Vornicus> | A couple years back I did business credit report collection from a couple of companies for a website - Experian and Equifax were the big ones. The difference was very interesting: Experian wanted data flow information and so forth to show that we were correctly connecting to them (including full certificate verification) and correctly storing and securing the resulting data. Equifax didn't bother asking at all. |

| 04:39 | <&Derakon> | Hooray, mapgen is deterministic. |
| 04:39 | <&Derakon> | Finally tracked down the last source of undefined ordering; my Path class had not implemented __cmp__, so even though I was sorting a list of Paths before iterating over it, the sort was just going by their object IDs. |
| 04:39 | <~Vornicus> | Hooray |
| 04:40 | <~Vornicus> | That would do it. |
| 04:52 | <&Derakon> | So that's four days' of hobby time down the drain fixing that whole mess. |
| 04:53 | <&Derakon> | When it comes to programming, take my advice: don't make mistakes. |
