Hello Cybersquir,
Why don’t you simply use the Find in Files dialog, with a suitable regular expression ? Of course, all your concerned files should be located in a same directory !
IMPORTANT : As you intend to change many files, simultaneously, may I suggest you to do a copy of this directory, as a backup, first ?
Now, open the Find in Files dialog ( CTRL + SHIFT + F )
Choose the absolute path of the folder, containing all your files
Possibly, filter with one or several specific extension(s)
Set the Regular expression search mode
Check/uncheck the other options, as needed
Then, for instance :
To remove the first 5 lines of every file, of this folder, use :SEARCH \A(?:.*\R){5}
REPLACE Nothing
To change some consecutive tabulation characters with a comma, use :SEARCH \t+
REPLACE ,
And so on…
Best Regards,
