NO match word and perform find and replace in sed

[ianirudhrawat]

there is Exception when we try " match word and perform find and replace ".
Eg. sed "/^hello/s/tom/jerry/g" gives "invalid sed arguments" exception .
its a functionality supported in sed

Hi there Ian,
Unfortunately the (unix4j) sed command doesn't support sequential sed commands. e.g. a search followed by a search/replace.

Another approach might be:

System.out.println(Unix4j.fromString(input)
        .grep(Grep.Options.v, "hello")
        .sed("s/tom/jerry/g")
        .toStringResult());

Cheers,
Ben
