system “apt-get install gaim”

I’d recommend using pidgin – it’s the newest release of gaim.

Use the Kernel#system method, or surround the command with backticks.

system(“apt-get install gaim”)
apt-get install gaim

Please do not thread-hijack. You should create a new message rather
than changing the subject line unless the new subject has something to
do with the original discussion.

My apologies it was done inadvertently.

for posterity, this does run through the shell, rather it replaces
ruby with the argument to exec (another process) completely by-passes
the shell. you need to use system or popen to utilize the shell.
