I have a variable like this:
var1=Makefile .xcompile /root/build/.config src/arch/i386/Makefile.inc
means some words separated by spaces. I want to print each word on a
separate line. I think I have to use "awk" or "sed" string processing
tools. I wonder if anybody have experience with them or any other
means to do it.
Neither:
var1='Makefile .xcompile /root/build/.config src/arch/i386/Makefile.inc'
v2=($var1) # Now v2 is an array with the elements delimited by IFS
IFS=$'\n' # Change IFS to newlines and use it as the separator
# when expanding using [@]
echo "${v2[*]}"
Easy peasy.
