for loop problem

mdap · #1 (**permalink**) 08-16-2008

hi,

how do you create a loop command given the following requirements?

go = ( out1 out2 out3 )

for i in go
do

echo $go

done

the script aboe does not work for me.

what i want the script to do is it will echo each variable until it reaches the last variable inside go.

im assuming that the output would be somewhat like:

out1
out2
out3

thanks.

Place the string between quotes and there should be no spaces around the "=" sign:

Code:

go=("out1 out2 out3")

for i in $go
do
  echo "$i"
done

The parentheses might also need to be taken out, depending on your shell.

Code:

go="out1 out2 out3"

The for loop simply splits its arguments on whitespace.

ya era i am agree with you "(" may not work in all shell
or else you can simply try
echo "$go"|awk '{printf $1"\n"$2"\n"$3"\n"}'
provided you have less no of out
