in reply to print +split

The + is there to keep print from thinking those parentheses contain its argument. You are missing the $ on diff in your if. The if doesn't match because the line does not start with digits.

use strict;
would have helped you some. Some judicious print statements would also be enlightening. The code is getting pretty bletcherous. Did you copy some of these constructs?

I've updated it just enough that it runs and you can see what you've got. I don't know where you want to take it from here.

use strict; use warnings; my $dev = qw/original1/; my $dev1 = qw/clinical1/; my $diff=0; # open (FOO, "samcmd a $dev 2>\&1 |" ) || die # "unable to open pipe... Broken? $!"; while (<DATA>) { if (/regular files|archdone files/) { local $, = "\n"; #s/^\w+(\s+)\w+(\s+)// && s/,//,; s/,//, print +(split)[2], $,; if (/^\d+/) { $diff -=$1; ##--## 62622-62535 } else { print "$_ does not start with digits.\n"; } } } print "Difference is: $diff\n"; #close (FOO) or warn "unable to close file $!"; __DATA__ regular files 62,622 597.488G 641547379187 archdone files 62,535 597.008G 641032761295

    yes Roy, thanks but I intended to paste everything including use strict, but forgot. The missing $ was a mistake...sorry I have the same code and it is not subtracting the two values 62622 and 62535.
    use strict; use warnings; use diagnostics; use MIME::Lite; use Logfile::Rotate; $ENV{"PATH"} = qq(/opt/SUNWsamfs/sbin:/usr/bin:/usr/sbin:/usr/local/lo +g); ########## ## Fuji ## ########## my $dev = qw/original1/; my $dev1 = qw/clinical1/; my $diff=0; open (FOO, "samcmd a $dev 2>\&1 |" ) || die "unable to open pi +pe... Broken? $!"; while (<FOO>) { if (/regular files|archdone files/) { local $, = "\n"; #s/^\w+(\s+)\w+(\s+)// && s/,//,; s/,//, print +(split)[2], $,; if (/^\d+/) { $diff -=$2; ##--## 62622 - 62535 # I dont really need this if b/c # I know what $_ contains after the split # which is the two numbers. } } } __DATA__ regular files 62,622 597.488G 641547379187 archdone files 62,535 597.008G 641032761295
      Try:
      while (<DATA>) { if (/regular files|archdone files/) { local $, = "\n"; s/,//; print +(split)[2], $,; $diff[++$i] = (split)[2]; } } print $diff[1]-$diff[2],"\n"; __DATA__ regular files 62,622 597.488G 641547379187 archdone files 62,535 597.008G 641032761295

      Your code wasn't performing a subtraction. Also, as Roy mentioned the /^\d+/ wasn't matching.
        hey chas... where are you defining $i in $diff++$i??? I am not followinf you logic. Will you please provide some psuedo code?
        Chas.... I understand now... my bad. Anyway it is printing the two elements of not computing the difference.
        root@stkv440-srvA [ / ]-> perl /usr/local/bin/ohiohealth/filecp_chk.OH +.pl 64696 64684 Difference is: 64696 - 64684
        I got it... I was a matter interpolation in my print statement. THANK YOU CHAS!!!! : ) Have a nice week!
