Re^2: Using System command

I suspect that if you print your $cmd you'll see why:

cd C:\\ABC\\pdftotext -layout R1.pdf
[download]

Probably is not what you want to execute.

Perl has a builtin to change directory: chdir

In the command line, two commands have to been concatenated with & or && (NB: the latter && only execute the second command if the previous was succesfull ms odcs)

See a more userfriendly explaination at ss64.com for details.

Tried the below code `my $cmd = "cd C:\\ABC\\"; my $cmd1 = "pdftotext -layout R1.pdf"; system($cmd&&$cmd1);` [download] But the error this time is "'pdftotext' is not recognized as an internal or external command, operable program or batch file"	[reply] [d/l]

What is the following code supposed to mean? `system($cmd&&$cmd1);` [download] Maybe you wanted something like: `my $real_command = "$cmd && $cmd1"; warn "Running [$real_command]"; system($real_command) == 0 or die "Couldn't launch [$real_command]: $? / $!";` [download] Observe the difference between `my $real_command = "$cmd && $cmd1"; print $real_command; # and my $real_command = $cmd && $cmd1; print $real_command;` [download]	[reply] [d/l] [select]

Thanks a lot for that clarification @gods. It is giving proper results now with the use of quotes "" in the to form the final command. `system("$cmd && $cmd1");` [download]	[reply] [d/l]

Wait, the `&&` here is the shell operator, not the Perl one, so it should be `0 == system "$cmd && $cmd1" or die "Error: $?";` [download] As `$cmd` was true, the result of `$cmd && $cmd1` in Perl was just `$cmd` .
