Hi I'm looking for a script that searches through multiple files for a string and the line where this string is found should be moved three lines down, for example:



now what I want is for each time the script finds "host_name " it should move this complete line three rows down like this:



I have hundreds of these files and each file have host_name in it multiple time, I would be truly greatful if this could be automated somehow. Thanks in advance!

No easy way, I fear. You have to write the whole code that opens each file, reads it line by line and prints the line unless it is the line to move, in which case a counter is initialized and the line is remembered to be printed three lines later. I would probably use perl for that to make sure no host_name gets moved out of the curly brackets etc.

Seems to work but currently removes the tab formatting, it's something to start from

Same principle as DarthWavy, except in awk. Keeping any (tab)formatting as-is and possibly quicker than a 'read line' shell loop.
I'm not sure you want to move the host_name line '3 down' though. Perhaps you want to move it to the end of the section, before the closing curly bracket?

Thanks!I think having it right over the closing curly bracket would work great! might be more error proof if the syntax is of in some cases! would be great if you could edit the script, thanks a bunch! I love this site! (and everyone who posted their suggestions!! thanks!! ):)
