Try switching the double quotes for single quotes, and the single quotes for double quotes. Here is yet another way to do it: `perl -le 'print join ",",map{chomp;$_}<>' file` [download] -enlil	[reply] [d/l]

That's OS dependent. On Win2K I get the error "> was unexpected at this time." using the switched quotes as you provided. (But `perl -le "print join ',',map{chomp;$_}<>" file` works just fine)	[reply] [d/l]

It's not really OS dependent so much as shell dependent. Windows' "command.exe" or "cmd.exe" uses double-quotes as string delimiters, whereas most other shells use double-quotes as an interpolating delimiter and single-quotes as non-interpolating. On those shells, you'd almost always want to use single-quotes with a Perl one-liner so something like `$var` isn't interpreted by the shell itself, as it would be in double-quotes. With Windows, you have to use double-quotes because that's all it recognizes, so you'd need to switch any quote marks inside those to single quotes. Or just use `bash` with Cygwin. kelan Perl6 Grammar Student	[reply]

I get the same type of error on Windows, but currently I assumed (and perhaps erroneously), that since he was using cat that he was not working at a windows/dos command (cmd) prompt, but rather a *nix one (or cygwin on windows, perhaps). So switching the quotes would/should have helped. -enlil	[reply]
