Won't the /dev/full device fail when you try to write to it long before you get to close it?


Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.

    No…

    $ perl -MFatal=open,close,syswrite
    -e'open $fh,">/dev/full"; syswrite $fh, 1; close $fh'
    Can't syswrite(GLOB(0x8130c24), 1): No space left on device at (eval 3) line 3
    	main::__ANON__('GLOB(0x8130c24)') called at -e line 1
    $ perl -MFatal=open,close
    -e'open $fh,">/dev/full"; print { $fh } 1 or die "$!\n"; close $fh'
    Can't close(GLOB(0x8130c24)): No space left on device at (eval 2) line 3
    	main::__ANON__('GLOB(0x8130c24)') called at -e line 1

    … not with buffered I/O.

    Makeshifts last the longest.
