perl one-liner issue
I am trying to deduce the one liner for an rpm I am packaging to edit a php configuration file from within my spec. The line I am editing looks like: $conf['nagios_base'] = "/nagios/cgi-bin"; What are the escape requirements Perl needs from within the shell to search for this? As I have seen, the syntax is a mess, any pointers would be appreciated! thanks, jlc

[OT] Witty one liners or computer related proverbs
Dear All, I need some witty computer related proverbs or one liners that some of have used in the past as footers for your emails for example. I particularly remember a PERL based transliteration joke/footer that when run in PERL produces a witty output.... This is to fix a problem internally created by an over zealous salesman at my company pinning up A4 sheets with bullSh*t sales proverbs

A one-liner to create a 3-dim array
Hi, I would like to write a one-line R code to create a 3-dim array, B, of dimension (n,n,m) from a matrix, A, of dimension (m,n) such that the i-th element of the 3-dim array, B[, , i] is the outer product of the i-th row of A. Thanks for any help, Ravi. [[alternative HTML version deleted]]

awk global replacement only after keyword
Trying to avoid a perl script which wouldn't be hard, but I am looking for an awk one liner that does a replacement, but only after it sees a key word on some line. Anyone know of that's easy to do? Thanks! jlc

categorized complete list of R commands?
every time I read the R release notes for the next release, I see many functions that I had forgotten about and many functions that I never knew existed to begin with. (who knew there were bibtex facilities in R? obviously, everyone except me.) I wonder whether there is a complete list of all R commands (incl the standard packages) somewhere, preferably each with its one-liner AND

looking for one-liner for strsplit and regex
Hi, I have a line such as: myline <- " 0.100000 1.5000 0.6000 538 0.369404" and I would like to put the numbers into a vector. Some combination of tabs and spaces occur between the numbers. I tried: try1 <- strsplit(myline,"[[:blank:]]+") > try1 [[1]] [1] "" "0.100000" "1.5000"

Need help with awk one-liner
This awk command pulls URLs from an apache config file, where $x is the config filename. awk '/:8008\/root/ {printf $3 "\t"}' $x The URL that is output by the script looks something like this: ajpv12://hostname.network.company.com:8008/root Is there a way to alter the output so it only shows "hostname" by itself? Do I need to pipe this through awk again to clean it

"reverse" quantile function
Peter, thanks, very nice, this will work for me... could you also help with setting up the code to run the on liner "approx(sort(x), seq(0,1,,length(x)), q)$y" on the rows of a data frame using my example above? So if I cbind z and res,? df<-cbind(z,res) the "x" in your one liner would be the first 4 column values of each row and "q" is the last (5fth) column

Creating a simple sum (or: I suck at blocks!)
I''ve been hacking on this for awhile and am not even getting close. Consider the following... results = Sample.find(:all) total_counter = results.each{|result| #Add together result.counter} I just want to simply iterate through the list and sum the counter field for each row into an aggregation. I could do it in a full for loop, but is there a nice one liner I''m missing?

Here''s how I did it. def commify(number) c = { :value => "", :length => 0 } r = number.to_s.reverse.split("").inject(c) do |t, e| iv, il = t[:value], t[:length] iv += '','' if il % 3 == 0 && il != 0 { :value => iv + e, :length =>

Dtrace Snooping
Dear dtrace Experts, I have seen some dtrace utilities like opensnoop and execsnoop etc. My interest is to write a simple script that can snoop the files which uses the 3 syscalls like open,create,unlink. I have gone through dtrace oneliners that can do the same : dtrace -n ''syscall::open*:entry { printf("%s %s",execname,copyinstr(arg0));}'' dtrace -n

shelling out to R for one command
I am developing a PHP script and want to use R to get the probability of a t-value. This just requires that I issue one R statement and output the result. The problem I am having is that R will accept batch input but I am not sure that it will accept a "one-liner" (i.e., "/usr/local/bin/R qt(.975, 20)" does not work but you get the idea). Is there a way to pass R a

Turning a logical vector into its indices without losing its length
I have the code below which gives me what I want for temp based on logvec but I was wondering if there was a shorter way ( i.e : a one liner ) without having to initialize temp to zeros. This is purely for learning purposes. Thanks. logvec <- c(TRUE,FALSE,FALSE,TRUE,FALSE,FALSE,TRUE,FALSE) temp<-numeric(length(invec)) temp[invec]<-which(invec) temp [1] 1 0 0 4 0 0 7 0 obviously, the

S. function calculating x +- y
Hello, I am looking for an elegant one-liner for the following operation: x <- rnorm(10) y <- runif(10) c(mean(x)-mean(y), mean(x)+mean(y)) I thought about apply(data.frame(x, y), 2, mean) but I don't know how to apply the +- operation on the result of apply.
