rename a string in a perl script eg name("this stays the same") -

- 

perl -pi-back -e 's/actual_word\(`something`\)/expected_word\(`something`\)/g;' \ inputfile.txt

i need "something" stay same. variable changes.

i think should it?

perl -pi-back -e 's/actual_word(.*)/expected_word($1)/g;' inputfile.txt

you capture word in brackets , reuse via $1 in replacement. (you may need more brackets - it's unclear if additional required based on input).
