Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I know it is pretty trivial but anyway...
I have php file that I am trying to read it looks like this
add_item_tabulky("Andílek na sáňkách","sanky.jpg","","","");
I dont*&^(^belong here
there are lines that begin with add_item_tabulky and also "weird lines" that dont begin with that...
now I need to echo both lines to a file but I need to transform the add_item_tabulky_line s first.
so I tried somehting like:
2 while read line
5 if [[ "$line" =~ "add_item_tabulky(.*" ]]
7 echo $line
9 done < $1
well bad news it has no output at all! Why is that? It is not the whole (rather complicated script but I just cant get this to work
Try taking the . out. A bash pattern is not the same as a regular expression so . there means ' not "any character". You could also remove the * because the =~ operator matches anywhere in the line, not the whole line. If you want to anchor the pattern to the beginning of the line use ^. The quotes on the RHS of a =~ operator are taken as part of the pattern so are not needed (I'm a little hazy about this -- could be bash version dependent).
Putting those all together gives (not tested) if [[ "$line" =~ ^add_item_tabulky( ]]
