Change all single-quotes to double-quotes in your shell script, like so -

Code:
$
$
$ cat word_extractor_script.sh
perl -p -e "s/^.*?$1/$2/" cleanme > CleanerExtract
 
sed "s/^/$1 /g" CleanerExtract > CleanerExtract1
 
sed -n "/$2/p" CleanerExtract1 > CleanerExtract2
 
sed G CleanerExtract2 > CleanerExtract3
 
sed -e "s/.*$1//" -e "s/$2.*//" CleanerExtract3 > CleanerExtract4
 
sed "/^.\{1000\}/d" CleanerExtract4 > OutputShorter_$1_$2
 
rm CleanerExtract
rm CleanerExtract1
rm CleanerExtract2
rm CleanerExtract3
rm CleanerExtract4
$
$

It should work thereafter -

Code:
$
$ # show the contents of file "cleanme"
$ cat cleanme
There is a cat next to a dog. The dog is next to the cat. The elephant is behind the dog but under the cat which is to one side of the elephant and underneath the dog.
$
$ # show the contents of script "word_extractor_script.sh"
$ cat word_extractor_script.sh
perl -p -e "s/^.*?$1/$2/" cleanme > CleanerExtract
 
sed "s/^/$1 /g" CleanerExtract > CleanerExtract1
 
sed -n "/$2/p" CleanerExtract1 > CleanerExtract2
 
sed G CleanerExtract2 > CleanerExtract3
 
sed -e "s/.*$1//" -e "s/$2.*//" CleanerExtract3 > CleanerExtract4
 
sed "/^.\{1000\}/d" CleanerExtract4 > OutputShorter_$1_$2
 
rm CleanerExtract
rm CleanerExtract1
rm CleanerExtract2
rm CleanerExtract3
rm CleanerExtract4
$
$ # execute the script passing "cat" and "dog" as parameters
$ ./word_extractor_script.sh cat dog
$
$ # show the contents of "OutputShorter_cat_dog"
$ cat OutputShorter_cat_dog
 which is to one side of the elephant and underneath the
$
$

In any case, are you trying to do this ?

Code:
$
$ perl -plne 's/^.*cat(.*?)dog.*$/$1/' cleanme
 which is to one side of the elephant and underneath the
$

You don't need so many calls to sed in such a case.
