I am writing a long bash script under CentOS 7 where perl is used for 
manipulating some external files. So far I am using perl one-liners to do so 
but ran into a problem when I need to append text to an external file.

Here is a simplified example in the bash script where txt is a bash variable 
which I built containing a longish text with multiple newlines:

txt="a b$'\n'cd ef$'\n'g h$'\n'ij kl"

A simplified perl one-liner to append the text in the variable above to some 
file in the bash script would be:

perl -pe 'eof && do{print $_'"${txt}"'; exit}' someexternalfile.txt

This works when fine when $txt does /not/ contain any spaces but falls apart 
when it does.

In a shell script why not stick to shell tools?

  printf "%s" "${txt}" >> someexternalfile.txt
