Since the source file and destination file are the same, consider doing something like this.

Input file called inputfile.txt contains just the word 'This'

commandline
perl -pi -w -e 's/This/I did it/g;' inputfile.txt
#This replaces the word This with I did it all from the commandline

inside script called myscript.pl
perl -pi -w -e 's/This/I did it/g;' $1
#Put this perl line inside a script and run it. Passing your input file to the script

Run script from commandline.

#myscript.pl inputfile.txt

-X
