Eu tenho o código abaixo no arquivo perl. A intenção deste comando é adicionar uma linha "- - test 0" no final do arquivo.txt.

system(" find  . -type f -name file.txt | xargs sed -i -e "$ a- - test 0" ");

Quando tento executar o script, recebo o erro mostrado abaixo.

Scalar found where operator expected at timeStampConfig.pl line 24, near "" find  . -type f -name file.txt | xargs sed -i -e "$ a"
    (Missing operator before $ a?)
Number found where operator expected at timeStampConfig.pl line 24, near "test 0"
    (Do you need to predeclare test?)
String found where operator expected at timeStampConfig.pl line 24, near "0" ""
    (Missing operator before " "?)
syntax error at timeStampConfig.pl line 24, near "" find  . -type f -name file.txt | xargs sed -i -e "$ a"
Execution of timeStampConfig.pl aborted due to compilation errors.

Tentei executar a linha abaixo no prompt de comando e funcionou bem.

find . -type f -name file.txt | xargs sed -i -e '$ a- - test 0'

Também tentei usar aspas simples conforme mostrado abaixo, mas acabei com um erro.

system("find  . -type f -name file.txt | xargs sed -i -e '$ a- - test 0'");

sed: -e expression #1, char 1: unknown command: `-'

Sou novo em perl, preciso de ajuda com isso.
