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

do it step by step. (also you could use an alternate delimiter , such as "|" instead of "/"

function parseDates(){
    #Some process here with $1 (the pattern found)
    return "dateParsed;
}

value=$(parseDates)
sed -n "s|[0-3][0-9]/[0-1][0-9]/[0-9][0-9]|& $value &|p" myfile

Note the use of double quotes instead of single quotes, so that $value can be interpolated
