<0> there's something simple here: /usr/local/sbin/server -d -q -xv 2>&1 > /tmp/output <--- why does that not redirect standard error into the file?
<0> i used to know the answer to this.. :(
<1> because the order matters
<1> read redirections from left to right
<0> it's >/tmp/output 2>&1 isn't it
<2> hi guys, is there any way to make the bash pager more less-like?
<1> 2>&1 >foo : redirect stderr to WHERE STDOUT GOES (terminal); redirect stdot to file foo
<3> kothog, You're redirecting stderr to stdout and then redirecting stdout to a file. Should be the other way around
<1> voidy: the bash pager?
<1> voidy: ah, you mean for m***ive completion options and so?
<0> ah, right. duh. thanks guys, much obliged.
<2> or any options to stop you having to press enter and risk tapping enter on the half finished commandline that your tab-completing?
<2> it's the only thing that drives me mad about bash hehe
<2> aye yes
<4> i can't seem to pad with zeroes on 'seq' command, AND, keep width to be 4 digits
<4> -f and -w are mutually exclusive
<4> any tips?
<5> !faqzero
<6> http://wooledge.org/mywiki/BashFaq#faq18 -- How can I use numbers with leading zeros in a loop, e.g. 01, 02?
<1> voidy: seems you can only switch on/off (readline: page-completions)
<2> so i can just scroll back up the terminal to see the list rather than using a pager.. that works :)
<1> heh
<2> it'd be nice if you could pipe them to an external pager though
<2> perfect
<2> echo 'set page-completions off' >> ~/.inputrc
<1> not really interesting
<7> bah... whats the awk one-liner to add up a column again?
<8> anyone need a script?
<7> nvm found it in my #bash logs..
<7> Jun 30 15:19:13 <greycat> awk '{sum += $1; n++} END { print sum / n }'
<1> that's the average value of the column 1
<7> oh yea... fixed ot gived sum..
<7> to*
<7> heh.. #bash logs usually answer most of my issues...
<1> naturally
<8> naturwtf?
<8> i used to answer day and night, now its more dead
<1> "naturgemaess"
<8> ts
<1> GNAH
<1> stop it
<9> if, during the course of a script, it asks a question then waits for input... how do i automatically provide an answer?
<1> type it
<10> roostishaw, therei s an application scripting languge called expect you can use that does just that
<11> roostishaw: in terminal: help read you could set read to timeout and set a var if it times-out
<9> ok, i think thats what ill do, thanks!
<12> I call a script in my bash_profile which is started as a background process. The script once invoked, sleeps for 60 minutes and then executes the main logic. The problem is that, once it is finished executing, any new shell then I open will start with a message "[1]+ Done script name".
<12> How can I supress this message? Will starting the script as a sub-shall help? Now I invoke it as /path/to/script 2>/dev/null & . Will it help to invoke it as ( /path/to/script 2>/dev/null & ) ?
<13> vishku: I am not sure. That message comes - I think - from some job control feature. Perhaps you can temporarily disable job control while you start the background script?
<13> vishku: Or maybe you can first start a Bourne-shell (without job control) and have that put the script in the background?
<12> MiniMax: Thanks, but I do not understand what you meant by job control feature. Is there some setting that I can change?
<12> MiniMax: Did a google. Do you mean commands like disown.. OK I was not familiar with the term
<13> vishku: Neither was I. I will go look at it. Thanks.
<13> vishku: disown sounds like a good candidate.
<12> MiniMax: I gave the entry like this : ( ~/bin/test 2>/dev/null & ) >/dev/null
<12> That seems to do it.. No status messages
<12> But I guess your idea about modifying job control settings seems to the correct path to take
<12> Anyway Thnaks much for your attention
<14> I am trying to limit the options a user can select to options 1 - 4 or q to quit the program. I have: read ans; while [ "$ans" != "q" -a "$ans" < 1 -o "$ans" > 4 ]; do; echo You must choose an option from 1 - 4 or q to quit.; read ans
<14> Can anyone tell me the correct way of doing this ?
<1> not > <
<1> -lt (less then) and -gt (greater then)
<1> [ is a normal command. and > means redirection. [ foo > bar ] will break into [ foo, redirect to bar and a useless ]
<1> i remember your nick from somewhere...
<1> #linuxhelp?
<1> yep.
<14> Yes, I'm still there too
<14> read ans; while [ "$ans" != "q" -a "$ans" -lt 1 -o "$ans" -gt 4 ]; do; echo You must choose an option from 1 - 4 or q to quit.; read ans
<14> Your right, I changed it to be like above.
<14> but now it's expecting an integer.
<14> I need the q option and 1 - 4.
<15> anyone know fcron well?
<1> seth1248: also i'd use a combination of a normal test and the bash arithmetic. try if `` while [ "$ans" != q ] && ((ans < 1 && ans > 4)); .... '' works
<1> Music|: never heard before. what's that?
<15> its basically a version of cron
<15> works with crontab, etc.
<1> what's the diff?
<1> i.e. what can it do what vixie's cron can't?
<15> "But fcron does not ***ume that your system is running neither all the time nor regularly : you can, for instance, tell fcron to execute tasks every x hours y minutes of system up time or to do a job only once in a specified interval of time"
<16> Translation... it's anacron.
<1> sounds like
<15> "contrary to Vixie Cron, fcron does not need your system to be up 7 days a week, 24 hours a day : it also works well with systems which are not running neither all the time nor regularly (contrary to anacrontab)."
<15> it works the sae really
<15> same*
<16> Ah, written by someone who has no actual experience with anacron.
<15> theres a "fcrondyn" function that allows you to see dynamically what jobs are scheduled
<1> neat
<16> Music|: So, why would you replace regular cron with this? Doesn't seem to be much point to it.
<15> let me quote the rest...sec
<1> maybe he has a backup job on a backupserver which isn't always running (if such a thing makes sense at all)
<15> from what I gleaned, its good for scripting
<1> what do you need from fcron?
<15> although I dont know how it could better than crontab -l
<15> well a a few systems Im maintaining were loaded with Trustix, which came with the fcron
<1> ah, as the standard cron service
<15> none of the cronjobs are running
<15> not even roots daily, etc scripts
<15> I know this because 1...they arent running....2...Im using the fcrondyn script and it shows 0 jobs
<15> reloading several OS's is not an option..so Im trying to troubleshoot it
<15> restarting fcron service is a no go
<1> and it doesn't read the common crontab syntax?
<15> Ive tried all the basic crap
<1> .oO(logfles)
<15> it has its own syntax
<15> but if you do a crontab -e to edit, it links to fcrontab -e
<15> It seems to be entwined in cron
<15> so im baffled lol
<15> If it was regular crond, and jobs werent running although the daemon was up...what would u do?
<1> looking into my logs
<15> k
<15> what ****s is because of security concerns I cant even stick atd on this thing
<15> so I have a few scripts which I need to daemonize on each server, and I cant reload em :/
<17> hello
<1> y0
<17> i have man -t xinetd > xinets.ps
<17> and i want to convert xinetd.psd to pdf using ps2pdf
<17> in single line ?
<17> man -t xinetd > xinet.ps > ps2pdf
<17> that didnt work
<1> | ps2pdf - >foo.pdf
<1> the - might not be needed
<1> just try
<1> your basic mistake was to mix up a pipe | with redirection >
<17> man -t xinetd > xinet.ps | ps2pdf > xinet.pdf ?
<17> u mean
<1> man .. | ps2pdf >foo.pdf
<1> >xinet.ps will ALWAYS redirect to a file "xinet.ps"
<1> and you want it as input for the next program
<1> that's the pipe
<1> foo | bar | baz | meow >final_output.txt
<17> man -t xinetd outputs(>) xinetd.ps
<17> i want the output of that to be input of ps2pdf
<1> that's what a | does
<1> man -t xinetd | ps2pdf
<1> and i see that ps2pdf is a ****ty tool
<1> it wants filenames
<17> yeah
<1> "-" is the filename usually used for stdin (by convention)
<1> ps2pdf - output.pdf
<1> so, man -t xinetd | ps2pdf - xinetd.pdf
<1> should work
<1> (ps2pdf has a manpage, the - is mentioned there)
<17> that didnt
<17> umm lemme try that again
<1> it did here
<17> yup it did
<1> mainserver:/home/bonsai/tests# man -t test | ps2pdf - test.pdf
<1> mainserver:/home/bonsai/tests# file test.pdf
