There is no need to keep track of the number of lines with a separate
variable. Perl already does this with the $. variable. Also, a regex
that replaces everything is pointless, just assign to $_.
perl -pi -le '$_ = "something" if $. == 10' your_file
So if this was in a script rather than a oneliner how would it work?
I was playing and can not get it to work in an actual test script.
Not surprising since it's not correct.
perl -pi -e '$_ = "something\n" if $. == 10' your_file
See `perldoc perlrun` for a description of the command line switches.
As a script:
#!/usr/bin/perl
use strict;
use warnings;
while(<>){
if( $. == 10 ){
print "something\n";
}else{
print;
}
}
