Re^3: System call doesn't recognise '>'

system ('@array > $outfile');

That line doesn't do what you think it does. Single quotes don't interpolate. You want to use double quotes and you want to check the return code of system():

system( "@array > $outfile" ) == 0
    or die "Couldn't launch [@array > $outfile]: $!/$?";

`my @array = ($command, $arg1, $arg2, $arg3); system( "@array > $outfile" ) == 0 or die "Couldn't launch [@array > $outfile]: $!/$?";` [download] Results in: `Can't spawn "cmd.exe": No such file or directory at D:\advanced_progra +mming\test_syscall.pl line 29. Couldn't launch [C:\clover\clover.exe D:\advanced_programming\vb_van_m +otif.dat D:\advanced_programming\test.fa D:\advanced_programming\back +ground.fa > C:\clover\out.txt]: No such file or directory/65280 at D: +\advanced_programming\test_syscall.pl line 29.` [download] Again: If I paste the string `C:\clover\clover.exe D:\advanced_programming\vb_van_motif.dat D:\advanced_programming\test.fa D:\advanced_programming\background.fa > C:\clover\out.txt` in command line cmd.exe , it returns perfect output to the out.txt file.

Perl starts all programs through `cmd.exe` (or whatever the local shell is) when it finds one of `<>\|` in the command to execute. As we've established, `cmd.exe` is not in your path. You won't be able to launch any program with redirection through `system` until you fix that. Also read system which also tells you that.	[reply] [d/l] [select]

You're right. And I did read the `system` documentation - but I couldn't deduce that from it... Must be my inexperience	[reply] [d/l]
