How to split a line into words separated by one or more spaces in bash? [duplicate]

Answer 1

echo $line | tr " " "\n"

gives the output similar to those of most of the answers above; without using loops.


In your case, you also mention ll=<...output...>,
so, (given that I don't know much python and assuming you need to assign output to a variable),

ll=`echo $line | tr " " "\n"`

should suffice (remember to echo "$ll" instead of echo $ll)

Answer 2

More simple,

echo $line | sed 's/\s/\n/g'

\s --> whitespace character (space, tab, NL, FF, VT, CR). In many systems also valid [:space:]

\n --> new line

Answer 3

do this

while read -r line
do
  set -- $line
  echo "$1 $2"
done <"file"

$1, $2 etc will be your 1st and 2nd splitted "fields". use $@ to get all values..use $# to get length of the "fields".
