[Scottish] editors

[David Irvine]

Assuming your a glutten for punishment :)

cat - >>newfile will allow you to create files, ctrl-z when your done

now you can create files....

and assuming you have perl.....

you can now paste into your terminal the following:

#!/usr/bin/perl
#

my @lines;
my $line=0;

while (my $oldfile=<STDIN>){
@lines[$line++]=$oldfile;
}

my @newfile;
foreach $line(@lines){
print $line;
my $newline=<STDIN>;
if ($newline=~m/^\n/){
  push @newfile,$line;
 }else{
  push  @newfile,$newline;
  }
}

foreach $line(@newfile){
print $line;
}


which will give you a very crude text editor in perl....

so
$ perl foo.pl <oldfile 

it goes through each line and asks for the replacement line (I todl you
it was crude)

press enter if its correct, amend it if its not and when it gets through
each line it spits it all out. 

Of course you could add file handlers to save the file to a new name,
but that was just to illustrate the point.

You could also use awk or sed to amend the file. Remember when using
sed/awk not to redirect to the input file, since that has a tendancy to
hose it compeltely.
