How to convert values in a line to rows?
hi,

I am basically running a sql that returns me values and I have stored them to a variable for example value of the variable will be:

123 124 345

now I want to write values stored in the variable into a file as
123
124
345

thanks in advance

Code:
$ tr ' ' '\n' < infile > outfile

EDIT: sorry, from a variable you could do:
Code:
echo "$VAR" | tr ' ' '\n' > outfile

Try also:
Code:
x="123 124 345"
echo "${x// /$'\n'}"
123
124
345

Should work in recent bash, ksh.
