Re: Fool a process into thinking that STDOUT is a terminal

Hi, I tried playing around with your script, and it's acting funny for me with linux, perl5.8.0. When I run something like "./pseudotty ls -la" or "./pseudotty ps -aux" ; it sometimes will run and sometimes I get no output. There dosn't seem to be any pattern to it. If I run the commands rapidly in succession, sometimes they give output, sometimes nothing. I get the same problem from an xterm or console. Any idea why?

Hmmm... I guess it could be a version issue... I'm workin off of 5.005_03, also on linux. I suppose it could also have to do with this issue listed in the docs for IO::Tty · Linux 2.2.x & 2.4.x Returns EIO instead of EOF when the slave is closed. Benign.

I found the current thread with the same need as the OP, and interestingly, 15+ years later with IO-Tty-1.12 / Perl 5.22.0 / Linux 4.17.19 i also get strange varying result with a simple 'ls -la': sometimes only the total line, sometimes a single line from the ls, sometimes to whole output... The best programs are the ones written when the programmer is supposed to be working on something else. - Melinda Varian	[reply]
