I have a somehow big file (almost 3000 lines long and thirteen columns). Some lines have no value at all or, at least, are incomplete. The columns' values that have no data are marked with a "-" and the corresponding line (the line that owns that value) should be discarded and not used.
Due to text formatting problems, any excerpt of the real data cannot be posted here. Sorry.
The first and second columns doesn't interest us, since they are just countries' names (first column) and year (the second one).
I take two columns per calculation and if some column value is missing (if it has a "-"), then, the corresponding line (the line that owns that value) must be discarded.
In order to discard the line, I use a simple conditional statement:
That is, if some column has a "-", the value (or line) is not used. $COL1 and $COL2 are defined through the command line.
Using the third and the thirteenth columns of the dataset aforementioned, I got this as a result:
cat .servers | while read LINE; do
ssh jason@$LINE $1
done
exit 1
./command.ksh "ls -l ~jason"
Why does this ONLY iterate on the first server in the list? It's not doing the command on all the servers in the list, what am I missing?
Thanks!

Hi. I've been playing around a bit. This isn't for any practical purpose-- it's really just a theoretical exercise. I wrote this little thing:
foreach num ( 6 5 4 )
awk -v "number=$num" 'BEGIN{for(x=0;x<$number;x++) printf "-"; printf "\n"}'
end
I would expect the following output:

If there exists a field in stdin, print it, otherwise, print hello.....
These print nothing:

Hi,
I am using korn shell.
until ]
do
echo "\$# = " $#
echo "$1"
shift
done
To the above script, I passed 2 parameters and the program control doesn't enter inside "until" loop. If I change it to until ] then it does work.
