I have a number of image files that have duplicates across case (ie file.jpg File.jpg). I need a script like the following except I want to completely remove all uppercase. I know that fslint can do this, but I want to do it in terminal because there are so many..
find . -maxdepth 1 -print0 | sort -z | uniq -diz The following script may do what you want (I have it set to echo what it would do, rather than actually do it, so you can see)
#!/bin/bash # This variable will always be in lower case. That means that if you do # l=Hello the result will be $l==hello. typeset -l l for f in * do l=$f # Forces to lowercase due to typeset if [ "$l" != "$f" -a -e "$l" ] then echo rm "$f" fi done So, for example:
$ ls FIle.JpG File.jpg file.jpg $ rem_case_dup.sh rm FIle.JpG rm File.jpg 
if diff >/dev/null 2>&1 will do it, lots of other choices too). $l can be different from $f right after you’ve assigned l=$f. Please do not respond in comments; edit your answer to make it clearer and more complete. (2) The use if -a (and -o) in […] expressions is discouraged. Consider using if [ "$l" != "$f" ] && [ -e "$l" ] instead. typeset features needed explaining; they've only been around for 25+ years, so aren't new! A couple of comments added. Why is -a discouraged? for loop to something like find . -type f | while read -r f - have the find` statement determine the scope of your checks; the rest of the loop will compare to files in the same directory as the upper case file was found in.
./mydir/myfiLe.jpgbe considered a duplicate of./otherdir/myfile.jpg?
