How can I list the file/directory names in a directory recursively that are the same, but with different capitalization/case? ex.:
INPUT (not the ls command, the directories):
[user@localhost ~/a] ls -R
.:
b
./b:
ize Ize
./b/ize:
./b/Ize:
[user@localhost ~/a]
OUTPUT:
/b/ize
If you have GNU uniq, you can sort case insensitively (-i), and use -d to print only duplicate lines:
find . | sort -f | uniq -di
As @StephaneChazelas mentioned in his answer, this might not do what you expect if you can have duplicate paths that only differ in case (like a/b/foo and A/b/foo).
