Substitution with sed + bash function

Question

my question seems to be general, but i can\'t find any answers.

In sed command, how can you replace the substitution pattern by a value returned by a simple bash fun

Answer 1

you can use the "e" option in sed command like this:

cat t.sh

myecho() {
        echo ">>hello,$1<<"
}
export -f myecho
sed -e "s/.*/myecho &/e" <

you can see the result without "e":

cat t.sh

myecho() {
        echo ">>hello,$1<<"
}
export -f myecho
sed -e "s/.*/myecho &/" <
