Exclude range of directories in find command
Firstly, you can help find
by using -prune
rather than -not -path
- that will avoid even looking inside the relevant directories.
To your main point - you can build a wildcard for your example (numeric 01 to 19):
find . -path './0[1-9]' -prune -o -path './1[0-9]' -prune -o -print
If your range is less convenient (e.g. 05 to 25) you might want to build the range into a bash variable, then interpolate that into the find
command:
a=("-path ./"{05..25}" -prune -o")find . ${a[*]} -print -prune
(you might want to echo "${a[*]}"
or printf '%s\n' ${a[*]}
to see how it's working)
For me, I found the find command as a standalone tool somehow cumbersome. Therefore, I always end up using a combination of find just for the recursive file search and grep to make the actual exculsion/inclusion stuff. Finally I hand over the results to a third command which will perform the actions, like rm to remove files for example.
My generic command would look something like this:
find [root-path] | grep (-v)? -E "cond1|cond2|...|condN" | [action-performing-tool]
- root-path is where to start the search recursively
- add -v option is used to invert the matching results.
- cond1 - condN, the conditions for the matching. When -v is involed then this are the conditions to not match.
- the action-performing-tool does the actual work
For example you want to remove all files not matching some conditions in the current directory:
find . -not -name "\." | grep -v -E "cond1|cond2|cond3|...|condN" | xargs rm -rf
As you can see, we are searching in the current directory indicated by the dot as root-path: then we want to invert the matching results, because we want all files not matching our conditions: and finally we pass all files found to rm in order to delete them: I add -rf to recursive/force delete all files. I used the find command with -not -name "." to exclude the current directory indicated normally by dot.
For the actuall question: Assume we have a directory using .git and .metadata directory and we want to exclude them in our search:
find . -not -name "\." | grep -v -E ".git|.metadata" | [action-performing-tool]
Hope that helps!
