Subject: Re: Is possible to return after exec cmd?

# since that is exec's feature. exec replaces current process.
# 
# maybe you want system or `
# 
# irb(main):004:0> `echo am still here `
# => "am still here\n"
# irb(main):005:0> system "echo am still here"
# am still here
# => true
 
ok, ok, if you really want to run exec, you can do something this stupid,

irb(main):012:0> `ruby -e "exec 'pwd'"`
=> "/root\n"
irb(main):014:0> system %q[ruby -e "exec 'pwd'"]
/root
=> true
