Printing output in columes

[Larshg]

Hi

I want to print a variable with spaces in front og it.

ex.
a=123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890

>echo $a - should loog like this
123456789012345678901234567890
123456789012345678901234567890
123456789012345678901234567890
>

all I want t do is to have a margin infront of the print - so that it won't use the first 5 spaces eventhou it shifts lines.

A nother thing is that I want only to ptint the first 30 caraters of $a

Thanks

Try something like this:

echo $a | fold -w 30 | pr -o 5 -t

thanks it works like a charm

How can I write something infront of it?
and how can I make a line brake right before the first 0


ex.
writing test infront of the first line, and making a line brake right before the first 0
test 123456789
012345678901234567890123456789
012345678901234567890123456789
012345678901234567890

How about:

[tt]echo $a | nawk '{
i=match($0,"0&quot-1
print "test " substr($0,0,i)
i++
for (; i<length; i+=30) {
print &quot; &quot; substr($0,i,30)
}
}'[/tt]

You may need to use just awk or gawk depending on your environment.
