Perl substitution using string that contains a dollar sign on windows

Question

I\'m using perl on windows and am trying to do a one liner using perl to substitute a placeholder in a file using a windows variable that contains a dollar sign. Does anyone kno

Answer 1

Use ' as regexp delimeter symbol. It will disable all variable substitution:

perl -p -i.bak -e "s'!MYPASSWORD!'%NEWPASSWORD%'g" a.properties

Answer 2

I presume you are getting password from user input. why not just do that in Perl without having to go through batch since you are already using Perl? Its easier. you can then use modules like Term::Inkey to mask password and stuff.
