sudo redirect to a file

When wanting to append some string to a file using sudo

[mihamina@dell-f17 ~]$ pdsh  'echo "sshd:LOCAL,41.190.237.66,41.188.46.121" | sudo tee  /etc/hosts.allow'
hosting: sshd:LOCAL,41.190.237.66,41.188.46.121
filer: sshd:LOCAL,41.190.237.66,41.188.46.121
recette53: sshd:LOCAL,41.190.237.66,41.188.46.121
prod53: sshd:LOCAL,41.190.237.66,41.188.46.121
recette52: sshd:LOCAL,41.190.237.66,41.188.46.121
prod52: sshd:LOCAL,41.190.237.66,41.188.46.121

And it gives:

[mihamina@dell-f17 ~]$ pdsh  'sudo grep sshd /etc/hosts.allow'
recette53: sshd:LOCAL,41.190.237.66,41.188.46.121
prod53: sshd:LOCAL,41.190.237.66,41.188.46.121
filer: sshd:LOCAL,41.190.237.66,41.188.46.121
hosting: sshd:LOCAL,41.190.237.66,41.188.46.121
recette52: sshd:LOCAL,41.190.237.66,41.188.46.121
prod52: sshd:LOCAL,41.190.237.66,41.188.46.121

npm run build base-href

Using NPM to specify base-href When building an Angular application, people usually use "ng" and pass arguments to that invocation. Typically, when wanting to hard code "base-href" in "index.html", one will issue: ng build --base-href='https://ngx.rktmb.org/foo' I used to build my angular apps through Bamboo or Jenkins and they have a "npm" plugin. I got the habit to build the application with "npm run build" before deploying it. But the development team once asked me to set the "--base-href='https://ngx.rktmb.org/foo'" parameter. npm run build --base-href='https://ngx.rktmb.org/foo did not set the base href in indext.html After looking for a while, I found https://github.com/angular/angular-cli/issues/13560 where it says: You need to use −− to pass arguments to npm scripts. This did the job! The command to issue is then: npm run build -- --base-href='https://ngx.rktmb.org/foo&
