I was looking at a log file and needed to highlight multiple search items to make the logs more readable. I got into multiple threads suggesting various cryptic vim commands but I was in no mood to remember them. So, I finally hit this.
This is a cool vim script which you can use to highlight multiple search patter. You can simply add a search term by doing

This is the third part of a seven-part article on famous Perl one-liners. In this part I will create various one-liners for calculations. See part one for introduction of the series.
Famous Perl one-liners is my attempt to create “perl1line.txt” that is similar to “awk1line.txt” and “sed1line.txt” that have been so popular among Awk and Sed programmers.
The article on famous Perl one-liners will consist of at least seven parts:
- Part I: File spacing.
- Part II: Line numbering.
- Part III: Calculations (this part).
- Part IV: String creation. Array creation.
- Part V: Text conversion and substitution.
- Part VI: Selective printing and deleting of certain lines.
- Part VII: Release of perl1line.txt.
After I’m done explaining all these one-liners, I’ll publish an ebook. Everyone who’s subscribed to my blog will get a free copy! Subscribe now!
The one-liners will make heavy use of Perl special variables. A few years ago I compiled all the Perl special variables in a single file and called it Perl special variable cheat-sheet. Even tho it’s mostly copied out of perldoc perlvar, it’s still handy to have in front of you, so print it.
I having been looking for something like this for sometime. Found this while searching.
A very good thing about this tutorial is its comprehensiveness and the details. A lot of examples are gives which too are quite useful.
