Problem with process

[Markus Blasl]

Hi,

can anyone give a hint, why ruby skips the input, when i run this
following code?

thanks,
Markus

#!/usr/bin/ruby
def search()
puts "Suchbegriff: ";
search=gets;
chop
search = $_
search = "Welt";
ARGV.each do |test|
File.open("#{test}", "r") do |afile|
if (afile.gets =~ /#{search}/i)
puts test.to_s
end
end
end
end
search()

 

[ts]

M> #!/usr/bin/ruby
M> def search()
M> puts "Suchbegriff: ";
M> search=gets;

search = $stdin.gets # otherwise ruby read a line from the
# first file given in argument, and this file
# is removed from ARGV

M> chop

This confused me the first time I saw it, and now I always use
$stdin.gets() instead of just gets(). Is there anyone out there who
actually uses this feature of Kernel#gets()?

Yep.
