If I'm doing quick and dirty scrips then I just shell using backticks and don't worry much about the commands not running. If I start to worry about errors then it's time to find a way to do it using perl calls. For your sample in this instance Sys::Hostname is available as a core module and has fallback and error reporting.

<slings-and-arrrows-off>Actually, as a confession, if the problem is going to need a large proportion of shell builtins then I just code in Bash.<slings-and-arrows-on> <\p>

s//----->\t/;$~="JAPH";s//\r<$~~/;{s|~$~-|-~$~|||s |-$~~|$~~-|||s,<$~~,<~$~,,s,~$~>,$~~>,, $|=1,select$,,$,,$,,1e-1;print;redo}
