Parsing Columns From Files WITHOUT awk

# awk is cool - but sometimes jumping from bash to awk to bash gets clunky. # We don't actually have use awk - we can just leverage bash internal parsing. # This is a classic awk example but now we have the really useful function map # which lets us do the same time in bash. function size_name {     print $5 $9 } function map {     local l;     while read -r l; do         $1 $l;     done } ls -l SonicField/src/cpp/lib/ | map size_name | column -t 168       build.sh 2108      stream.hpp 15676048  stream.hpp_out # Let's try this as a one liner: _tmp () { print $5 $9; }; ls -l SonicField/src/cpp/lib/ | map _tmp  | column -t # awk is simpler but not by much if we assume map is part of your utils ls -l SonicField/src/cpp/lib/ | awk '{print $5, $9}'  | column -t 168       build.sh 2108      stream.hpp 15676048  stream.hpp_out # But remember that awk is a separate process space so you do not  # have access to the bash state in the same way.
