Cannot make pipe for process substitution: Too many open files
Hi,
I've came across an issue with a script I've been writing to check DHCP addresses on an Solaris system, the script has been running reasonably well, until it hit the following problem:
I'm pretty sure this is down to scrappy coding (with me being the culprit - I'm still learning ).
Is there anyone here that could maybe provide a few pointers as to how I can clean up the following function to try and fix the problem displayed above (I've higlighed what is almost certainly the problem line in bold):
Thanks in advance

Well, this seems to be VERY many open files - use getconf OPEN_MAX to find out how many open files you're allowed for.
Why don't you read the date variables immediately from the pntadm output? Or, even better, create one single number in the form yyyymmdd (20130225 for today, run date +%Y%m%d) that you can compare in one go? Guessing about the output format from your code above, I'd propose sth. like (untested):
Plus, I'd guess, pntadm might as well give you an overall result list for all subnets, that you then can analyse against check list / final list.
The problem I have with the dates, is that pntadm -P <subnet> outputs the date for each IP address on that subnet in the mm/dd/yyyy format, this is why I took the current date and broke it into seperate numbers for easy comparison - again probably not the slickest way of doing it, considering each run of pntadm -Poutputs around 257 lines - but it's the best I've got.
Reading the data into an array was something I thought about, although I'm not very familiar with array manipulation i.e. writing/reading data to and from an array - so this idea didn't progress either.
Maybe my error has something to do with a while loop within a while loop...
I was not talking arrays, but files. Have pntadm output its info on ALL subnets into one file, and then you have your check file / final file. testing one against the other, you can select / reject the single info lines of interest having exactly two files open, not in excess of 1024 (which is OPEN_MAX on my linux box)
I would like to test open files usage in my system, if I want to create a process ( or script ) that can use a certain amount ( eg. 1000 ) of open files , is it possible to create such process ( or script ) ? (3 Replies)
I know that I can do this in bash
ver=${VERSION:-$DEFVERSION}
so ver is $VERSION if it's set but $DEFVERSION if $VERSION isn't set
I want to do the same thing as a macro in a Makefile and can't get it to work - maybe something like...
VER=$(shell ${$(VERSION):-$(DEFVERSION)})
Any help... (1 Reply)
