Excluding results of a ‘find’ command (inverting tests)
Tuesday, November 10th, 2009
In kind of a follow up to my previous post on using find and sed to search and replace multiple files, I found out something else.
I needed to find and replace something in every file, except for any files which had “.svn” in them. After struggling for a few fruitless minutes with -regex, I stumbled upon this example in the manual page:
find /sbin /usr/sbin -executable \! -readable -print Search for files which are executable but not readable.
The \! allows us to invert the tests after it. Perfect! All we need to do is use -regex to do our excluding:
find . -type f \! -regex ".*\.svn.*"
And we can now search and replace in all files except those that have “.svn” in them:
find . -type f \! -regex ".*\.svn.*" -print0 | xargs -0 sed -i "s/foo/bar/"
Neat. Note that, again, -regex is a GNU find only construct.
