NevDull’s Take On Things

GNU seq’s cousin on FreeBSD is… jot

September 24th, 2007

This is another of my placeholders for reference.

I’ve got a FreeBSD system which is lacking some of the tools which I’ve gotten used to having, whether from Linux or Solaris.

I’ll often use the GNU tool seq to iterate through things on the command line… for example, if I’m going to ping 192.168.1.20-40, I might, at my bash prompt,

for i in `seq 20 40`; do ping 192.168.1.${i}; done

Quite handy, though FreeBSD doesn’t have it, and I haven’t installed whatever port contains it.

So… I’ll use jot, now that I’ve once again looked up what it is and how it works.

The equivalent line to that above?

for i in `jot 21 20`; do ping 192.168.1.${i}; done
