Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Terminal - sequence of numbers in a for loop

sequence of numbers in a for loop

Say you need to ping every 5th IP address on your network .. this will give you a way of doing that.

jot can also do counting ... like

jot 4





download from http://oreilly.com/catalog/upt2/examples/#jot or fins athena-jot in rpm format


There are 5 alternatives - vote for the best!

Terminal - Alternatives

What others think

You mean just like seq?

seq 4 seq 2 6 seq 2 5 13

and pure SHELL,

BASH v3:

for (( num=5; num<51; num+=5 )); do echo $num; done

or BASH v4:

echo {5..50..5}

Why limit yourself to only numbers :P?

echo {A..Z}

and mix'n match:

echo {A..E}{1..3}

Yeah, Came here to ask why would you install (or write) jot when seq and the built-ins both work.... and are pretty standard...

Comment by ozymandias 422 weeks and 1 day ago

This was intended for machines that don't have gnu coreutils installed by default like hpux and solaris

You would need to download and install something anyway in that case

Have only used seq for numbers, but jot also does letters and words

Comment by chinkshady 422 weeks and 1 day ago

FreeBSD also doesn't have seq but jot.

thanks @chinkshady

And of course FreeBSD doesn''t have that messy bash in the base system. ;-)
