jot gotcha
Seeing that I run into this jot gotcha every couple of months while writing shell scripts, I thought I would add a reminder for myself here (and so that google can pick this up for me next time).
On FreeBSD, by default you don't get access to the seq command to generate sequences, so you naturally will use jot for your shell scripting needs for generating number sequences.
So for example, we want to start with 0 and increment to 4 (one cannot use variables in the bash sequence generator, so {0..$max} won't work here. So for example we have 5 logfiles that we want to grok on a server and another has 6 so instead of hardcoding the varible on each server like {0..4} where we have 4, {0..6} where we have 6, we use jot and some nasty piping commands to get that number.
root# jot 4 1 2 3 4
Okay so misread the manual very quickly and try:
root# jot 0 4 4 5 6 7 8 9 10 *snip* 93211 93212 93213 93214
Pass the number of iterations (5), start (0) and where it ends (4):
root# jot 5 0 4 0 1 2 3 4
