Shell script :: Reading a column from file & store it in array
20,538
Solution 1
You can also do:
name=( $(awk '{print $3}' ./info.txt) )
I find this a little simpler. You can then access the array like ${name[1]} ${name[2]} or use * instead of a number for all elements.
Solution 2
name=( $(cut -d ' ' -f 3 "./info.txt") )
will do what you want (starting with index 0 however).
