How do I pass xargs input one line at a time to subsequent command? For example I want to install rubygems by reading a text file as shown below, however the arguments are getting passed all at once to the 'gem install' command. I hace tried -L (max-lines) and -n (max args) options, but it didn't work. What's missing here?? Any help?
$ cat gem.list.1 mkrf rake xmlparser
$ awk '{ print $0 }' gem.list.1 | xargs -L 1 -0 -I name sudo gem install
name
ERROR: could not find gem mkrf rake xmlparser locally or in a repository
Or: cat gem.list.1 | while read PKG; do sudo gem install $PKG; done
