Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

So, i'd like to use that command but I am, on the other hand, not sure about how to use it? Where do I put the weblink into that comman?

thanks in advance,

Set it up as an alias, and feed the full url in as an argument.

Comment by Amorymeltzer 384 weeks and 2 days ago

Hm, the alias-version doesn't work, bash can't load the alias, if I try to use alias alias chan="curl $1 | grep -i "File

. chan won't be recommendet wenn pressing tab and the bash says "bash: a: No such file or directory", so what am I supposed to do?

best regards,


Comment by bugmenot 384 weeks and 2 days ago

there is some confusion, i'm using it as a function that i source at login, i've modified the command to reflect this. sorry for the confusion, it really does work quite well.
