Hello,
I am making this batch file :
as.sh
find="aaa";
perl -pi -e 's/$find/zzz/g' as.txt
and this file:
as.txt
aaabbbccc
When i run the as.sh, it gives :
zzzaaabbbccc
It is supposed to replace aaa with zzz, anyone knows why?
thx
Yes.
Oh, you want to know why too?
perl -pi -e "s/$find/zzz/g" as.txt
Using single quotes means $find is not expanded so perl sees: perl -pi -e 's//zzz/g' which means subsitute at the first opportunity, which is the beginning of the line.
__END__
I love Perl; it's the only language where you can bless your thingy.
Perl documentation is available at perldoc.perl.org. The list of standard modules and pragmatics is available in perlmodlib.
