When using the 'for i in`, how do you get it to read a whole line in the file? For example, I have a file 'A' with the following line in it: $ cat A Hello World So when I do for i in `cat A \| awk '{print $1}' I get i=Hello But I want it to equal Hello World Is it possible to do this with 'for i in' ?

use $0 instead of $1 , $0 is the whole line argument in awk

use IFS. In a script you can throw away the value if you're not needing it later. On the CLI, you need to save it OLDIFS="$IFS" IFS=$'\n' for i in `cat A`; do echo "$i" done IFS="$OLDIFS"
