Embedding Text in Find Output
We recently did a migration of large files to another server, and needed to create a bunch of redirect commands to point at the new location. This turned out to be quite easy with find. First, we need to find the files over 570K:
find . -size +570k -printf '%k %p\n'
|
The quotes after printf include both text and variables. %k is the size in K, and %p is the relative path of the file. The output looks like this:
1484 ./files/bigfile.exe
4148 ./files/biggerfile.exe
.
.
.

To copy these files into a single folder:
find . -size +570k -exec cp {} /placetostore/files/ \;
|
To create redirect statements suitable for httpd.conf:
find * -size +570k -printf 'Redirect permanent /%p http://new.example.com/%f\n'
|
The output looks something like this:
Redirect permanent /files/bigfile.exe http://new.example.com/bigfile.exe
|
The cool thing we didn't know was that you could embed text in the output of find. This made our job quite easy in this case, even easier than Perl!
