I appreciate the responses, but I don't think that's quite what I'm looking for. Adding a date to the file... really doesn't get me anywhere, nor does a manual file by file copy to replace. Let me try to clarify...

I have approx 3,000 .htaccess files I am planning on targeting with a script to update them all at once removing a specified RE.

/dir1/.htaccess
/dir1/sub1/.htaccess
/dir1/sub2/.htaccess
/dir1/sub2/nest1/.htaccess
/dir2/.htaccess
/dir2/sub1/.htaccess
/dir2/sub2/.htaccess
/dir2/sub2/nest1/.htaccess
etc...

I've used:

Code:

find <start_directory> -iname ".htaccess" -exec cp -v {} {}_bak \;

To create a backup of each .htaccess to sit along side the original in every directory, so it now sits like this:

/dir1/.htaccess
/dir1/.htaccess_bak
/dir1/sub1/.htaccess
/dir1/sub1/.htaccess_bak
/dir1/sub2/.htaccess
/dir1/sub2/.htaccess_bak
/dir1/sub2/nest1/.htaccess
/dir1/sub2/nest1/.htaccess_bak
/dir2/.htaccess
/dir2/.htaccess_bak
/dir2/sub1/.htaccess
/dir2/sub1/.htaccess_bak
/dir2/sub2/.htaccess
/dir2/sub2/.htaccess_bak
/dir2/sub2/nest1/.htaccess
/dir2/sub2/nest1/.htaccess_bak
etc...

Now I'm going to run a script through all the original .htaccess files using find and sed -i to remove a selection of unwanted rewrite rules, while leaving the remaining rules in place. I'm pretty sure it is going to go as planned, but I want to be on the safe side and have backups in place, and a method to restore the original .htaccess files with the backups that reside along side them, if something goes wrong.

I need a method to find all .htaccess_bak files and rename them as .htaccess to overwrite the .htaccess files that are sitting along side them.

So in other words:

/dir1/.htaccess_bak is renamed to /dir1/.htaccess ... overwriting and replacing the .htaccess that is in place.
/dir1/sub1/.htaccess_bak is renamed to /dir1/sub1/.htaccess ... overwriting and replacing the .htaccess that is in place.
/dir1/sub2/.htaccess_bak is renamed to /dir1/sub2/.htaccess ... overwriting and replacing the .htaccess that is in place.

leaving a file structure like the original.

/dir1/.htacces
/dir1/sub1/.htaccess
/dir1/sub2/.htaccess
etc

But I need to do this for 3000 files at one time, not a cp or mv or rename... one by one by one manually..

I think this can be accomplished much along the lines of what I'm already using to create the backups. something like...

Code:

find <start_dir> -iname ".htaccess_bak" -exec rename {} {.htaccess} \;

I'm pretty sure the syntax there isn't correct, but I think it gives you an idea of what I'm trying to accomplish.

Any other thoughts or tips?

Thanks much!

SYNOPSIS

       dircmp [-ds] [-w n] dir1 dir2

DESCRIPTION

       The  dircmp  command  examines dir1 and dir2 and generates various tabulated information about the contents of the directories. Listings of

OPTIONS

       The following options are supported:

       -d      Compares  the  contents	of  files with the same name in both directories and output a list telling what must be changed in the two
	       files to bring them into agreement. The list format is described in diff(1).

       -s      Suppresses messages about identical files.

       -w n    Changes the width of the output line to n characters. The default width is  72.

OPERANDS

       The following operands are supported:

       dir1    A path name of a directory to be compared.
