Bear,
For trouble shooting, it will be helpful to separate the command
from the parameters. And it is better programming since you
control the executable and only let the user provide the
arguments. Ex:
my $tmp = `ls *.txt | fgrep -i "pattern"`;
could turn into
my $tmp = `ls` *.txt | fgrep -i "pattern";
Which is a little safer than giving the user total control of
the command. Maybe ls is not the best example, but hopefully the
idea is OK?
Good luck on the dead line,
Michael
