linux - Why doea $IFS act as a whitespace in the command "ls$ISF-l" but not "Echo hello"? -


ls -l has same output ls$isf-l, echo$ifshello not have same output echo hello.

i'm aware $ifs default equal white space. i'm wondering why $ifs behaving differently in between these 2 scenario.

peace.

in case "echo$ifshello" there no variable name "ifshello". need "echo${ifs}hello" same output "echo hello"
