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.

Universal configuration monitoring and system of record for IT.

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.

Your command is appreciated, especially for those who use gnuplot 4.2.4

Comment by Sunng 291 weeks and 4 days ago

which version does your command work with? I could not get it to work with 4.2.4. I see that the latest is 4.2.5, is that what you are using?

Comment by syssyphus 291 weeks and 3 days ago

yes, since gnuplot 4.2.5, the -e option is introduced in...

Comment by Sunng 290 weeks ago

oh, well that stinks, then your command is just fine, i bet people voted you down because they were running 4.2.4 or earlier, if you want i will delete my command, lemme know.

Comment by syssyphus 289 weeks and 6 days ago

oh, you don't have to. I know many people still running gnuplot 4.2.4 on thier ubuntu jaunty. Your command will be helpful and appreciated for them.
