command-line – How to Display Numbers in Reverse Order Using seq(1)

Do you mean jot?

$ jot 
jot: jot - print sequential or random data
usage:  jot [ options ] [ reps [ begin [ end [ s ] ] ] ]
Options:
    -r      random data
    -c      character data
    -n      no final newline
    -b word     repeated word
    -w word     context word
    -s string   data separator
    -p precision    number of characters

If you use Ubuntu the package is athena-jot. A simple example:

$ jot -r 10 12 27
26
13
22
18
25
12
13
23
15
23

Bye.

You can just pipe the output to shuf.

$ seq 100 | shuf

Example

$ seq 10 | shuf
2
6
4
8
1
3
10
7
9
5

If you want the output to be horizontal then pipe it to paste.

$ seq 10 | shuf | paste - -s -d ' '
1 6 9 3 8 4 10 7 2 5 

$ seq 10 | shuf | paste - -s -d ' '
7 4 6 1 8 3 10 5 9 2 

$ seq 10 | shuf | paste - -s -d ' '
9 8 3 6 1 2 10 4 7 5 

Want it with commas in between? Change the delimiter to paste:

$ seq 10 | shuf | paste - -s -d ','
2,4,9,1,8,7,3,5,10,6
