You can use this when you need to process a grep output:

echo "some/path/exex.c:some text" | awk -F: '{ "basename "$1"" |& getline $1; print $1 " ==> " $2}'

"basename "$1"" execute shell command basename on first field

|& getline $1 reads output of previous shell command in substream

output:
exex.c ==> some text
