Your problem here could well be that your command line shell is consuming the \ before the $ so there's no \ in the Perl program you are executing (What command shell are you using?) The RHS of s/// is a double-quotish string context you Perl thinks you are trying to interpolate the perl variable $bURL. You need to protect the $ twice. There are numerous ways to do this. Assuming a Bourne-like shell any of the following should work perl -w -i -p -e "s/testtext/<% \\$bURL %>/g" test.html perl -w -i -p -e "s/testtext/'<% \$bURL %>'/eg" test.html perl -w -i -p -e 's/testtext/<% \$bURL %>/g' test.html perl -w -i -p -e "s'testtext'<% \$bURL %>'g" test.html -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
