bash for loop multiple statements
# Basic syntax: for i in a b; do echo $i; printf "$i\t$i\n"; done # Where: # - each command in the for loop needs to be separated by semicolons. Here # we echo $i and then print $i<tab>$i<newline> # - over several lines this would be equivalent to: for i in a b do echo $i printf "$i\t$i\n" done
