How about this:

If the {n...m} syntax changes in a future version of bash, you'll need to
change the case.
It'd be nice if --version wasn't so wordy or you could get just the version
like uname -r

There's a bunch of others with similar good info, too. They're not exported in the external environment (because they're internal shell magic), so they don't show up with env. The bash(1) man page lists them under Shell Variables. Of course, knowing how much the world tends to suck, I'm guessing BASH_VERSION is not available in all versions of Bash... ;-) -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Funny, right after I sent that (obviously should have been right before)
I tried the syntax at a prompt, and discovered it was wrong, and thought,
ah, screwed up again. But then again I can claim it was a comment

Re: [OT] xkcd
I tried the 28 hour day In 1973 I worked for Aetna Life and Casualty. The company's computers ran 24 hours a day, seven days a week. The operators there worked 12-hour shifts, so we only had two shifts of operators, not three. In order to work (more or less) 40-hour weeks, they really worked 36 hours, so there would be one team for the first part of the week, and one team for the second part of the week. That left one day uncovered, so one team worked a 48-hour week (four days), then they would switch off and the other team would work a 36-hour week. The company tried to make it so each team would eventually would get a Saturday and Sunday off (a real weekend), and each team would average out working a normal amount of hours (~40/week) when averaged out over the year. Ergo every two weeks the team that had been working four days would work seven days in a row, and the opposite team would get a week's paid vacation. When the second team came back from vacation, they would work 3 days, the first team would go to four days, and the whole cycle started again. It was complex, but just like the xkcd cartoon, they had charts that helped people plan. While the one-week of 12 hours/day twenty-six times a year was grueling, the seven days of no work twenty-six times a year (more or less) was also nice. Plus, since the jobs were basically the same, the operators could trade off if some special event came up that they wanted to attend. Holidays? You just got double timeand since you could trade off easily, and since Aetna was an equal opportunity employer from day one, it was easy to find someone who would work for you if you wanted the time off.

Unless you have Suse 10.1:

How many versions of bash should there be in /bin? And of everything else?
Oh yeah, xkcd. I tried the 28 hour day described in
http://www.xkcd.org/320/ a couple times, but concluded that I couldn't
shift four timezones each day. The goal was standalone time on DEC's PDP-10s
at night and bicycling time during the day (foliage season) on weekends.
When I was getting off that, I read about a blind college student whose
internal clock was synchronized to the tides even though he was far from a
seacoast. I tried that lunatic cycle for a month a couple years later,
going to bed at a Boston low tide. Worked quite well, though my manager
couldn't figure out when I'd be in. The overnight shifts were during the full
moon so it never got really dark. I'd like to do it again, but synced with
the other low tide, and spend all night with a telescope during new moon.

Doesn't work. You need the comma a separator within {...}. But even
http://xkcd.com{`seq -s, 1 327`}
doesn't work, because the output of Command Substitution is not
reevaluated for more shell syntax. You instead would need to generate
the supposed command line, and then use the eval builtin to have the
shell evaluate it again:
eval http://xkcd.com/\{$(seq -s, 1 327)\}
Of course, if you're using bash, then
http://xkcd.com/{1..327}
will do the job without all the messy syntax or the external program.
How about that. This thread is on-topic after all. ;-)
