Re^6: Epoch time conversion script

[hedkandi]

Hi lidden I used the while loop you provided and I'm getting this error

[root@H99A115 03]# ./convert
./convert: line 4: syntax error near unexpected token `{'
./convert: line 4: `while(my $line = $in){'

I removed the <> tags from <$in> and still the same error this is my input and output file:

open my $in, '<', 'q22adm_history' or die "Bummer: $!";
open my $out, '>', 'q22adm' or die "What: $!";

Well, the while loop lidden provided has no syntax errors, so show your code

I removed the <> tags from <$in>

that had nothing to do with the error, that was reading the file, that is readline

Hi anonymous monk Thank you for pointing that out. Here's the result again

# more perl_epoch
open my $in, '<', 'jabadm_history' or die "Bummer: $!";
open my $out, '>', 'jabadm.txt' or die "What: $!";

while(my $line = <$in>){
    if(my ($epoch) = $line =~ /^#\+(\d+)\s*$/){
        my $human_readable = `date -d \@$epoch`; # or:
        #     my $human_readable = scalar localtime $epoch;
        print $out $human_readable;
    }
    else{
        print $out $line;
    }
}
# ls -lrt jabadm_history

Well, perl is not executing that program

If you're not going to type  perl program you need to set the shebang correctly, for ex  #!/usr/bin/perl --
