What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Stay in the loop…

Follow the Tweets.

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.

What others think

I think is more useful if just use this like:

man -t YOUR_COMMAND | open -f -a preview

and this just work on Mac OS.

It's a function on my system because I find it's easier to remember this way (to each their own). I also commented (OSX) in the subject line in an attempt to be specific that this was for OSX only. Thanks for your feedback though.

this is awesome

Comment by katylava 470 weeks and 4 days ago

For a Gnome (linux) compatible version, try

TF=`mktemp` && man -t YOUR_COMMAND >> $TF && gnome-open $TF

I don't know how to get gnome-open to accept std in

Should be doable in KDE too (Anyone?)

For KDE:

man -t COMMAND | okular -

Thanks, this is great :)

furicle's tmp file version works here on Ubuntu. Awesome tip!

Comment by hank 460 weeks and 6 days ago

On Fedora 12, this seems to work better:

function man2pdf(){ man -t ${1:?Specify man as arg} | ps2pdf -dCompatibility=1.3 - - > ${1}.pdf; }
