[SOLVED] Need Help Scripting?

amber1 · 03-04-2013, 11:47 AM

I am new to scripting and just needed some help writing a script please. How can I write a script which prints the numbers 1-29 on one line of the standard output, with a white space between each number?

I would appreciate it if someone can please help.
thanks

What language do you want to use? In bash, it would be something like

Code:

for i in $(seq 1 29); do
    echo -n "$i "
done
echo ""

Seems homework... But try this one as well:

Code:

#!/bin/bash
i=1
while [ $i -le 30 ]; do
echo -n "$i "
i=$((i+1))
done
echo

Or just:

Code:

echo {1..29}

Yea after reading the first two was wondering why they were doing loops. Maybe as training?

Why dont you try reading over http://www.tldp.org/LDP/Bash-Beginne...tml/index.html so you can get a full understanding of what is actually happening here. The brackets in the echo will do something called "bash expansion" try looking up that term if you are curious.

When extended brace expansion (see post #4) is not available:

Code:

seq -s' ' 1 29

Post #7 was edited after I responded, so my response now makes no sense...it used to make sense, I promise!

I'll take your word for it

... in which case @amber1: don't edit posts, it just confuses people.

Or more precisely, don't edit your post to substantially change its content. It's normally considered better to edit your post to append content than to double-post, and of course editing your post to correct typos is fine
