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}
Comment by asmoore82 335 weeks and 5 days ago

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 335 weeks and 5 days 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 335 weeks and 4 days 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. ;-)
