Hi, I am trying to modify a LaTex file which is plain text.
The file contains lines similar to the following, but each line is
followed by text, so that:
Article 1 Cats
Article 2 Dogs
Article 3 Fish
Article 4 Ferrets
etc.
I would like to modify the file so that each referenced line is
changed as follows:
\subsection*{Article 1 Cats}
\subsection*{Article 2 Dogs}
\subsection*{Article 3 Fish}
\subsection*{Article 4 Ferrets}
Here's code which was suggested to me, but when I execute it I'm
returned to the command line and nothing happens:
#!/usr/bin/perl
s/^(Article\s+[0-9]+\s+\N*\S)/\\subsection*{$1}/gm
I called this script "Article" and saved it as article.pl
The usage then was $perl article.pl oldfile.tex newfile.tex
and I got the following error message:
Missing braces on \N{} at article.pl line 2, within pattern
Nested quantifiers in regex; marked by <-- HERE in m/^(Article\s+[0-9]+
\s+* <-- HERE \S)/ at article.pl line 2.
So I added braces as follows: \{N}
I ran the script again; there was no error message but no newfile.tex
either.
I then ran the program as follows:
$perl article.pl oldfile
And the response is the command prompt and the file hasn't been
modified.
any suggestions?
