Re^5: parent process stuck in read(2) on pipe opened to child process using backtick

This isn't really what I meant. Or how would you adapt this in any elegant way so that when put in a.sh, it runs the code in the script itself under a new process group? (The idea being that you could say my $x=`./a.sh` without creating an extra wrapper script.)

I am not sure it would work as advertised, but I woudl try something like `bash -i -c '(HERE GOES THE ORIGINAL CODE OF a.sh) & echo $!'` [download] Update: The echo would probably mess with the backticks. I should not link to a material I am not so familiar with :-)	[reply] [d/l]

I don't think this would work (for several reasons). Also, the `-c '...'` would result in a quoting mess with any real script code. I you think differently, please provide a complete modified `a.sh`, which, when killed, kills its subprocesses, but not the calling process.	[reply] [d/l] [select]
