duplicate files

How can I find a list of files that are named duplicates i.e. have same name but in different case that exist in the same directory?

Hi and welcome to LinuxQuestions!

From the top-level directory (if you need to descend recursively into a directory tree) you might try:

Code:

find | uniq -id

That doesn't produce anything useful when I try it.

I think the first thing to note is that "same name but in different case" is actually something of an oxymoron. If the case is different, they do not have the same name. E.g. hello and HeLLO are two different names.

The closest I've been able to get is this

Code:

mike@continuity:/tmp$ touch hello
mike@continuity:/tmp$ touch HEllO
mike@continuity:/tmp$ touch Hello
mike@continuity:/tmp$ find . -iname \* 2>/dev/null | sort | uniq -id 
./hello
mike@continuity:/tmp$

The output of the find command tells me that there is more than one file with a name that is a variant of hello. But it doesn't tell me that the other files are call. I can find them with another find command though

Code:

mike@continuity:/tmp$ find . -iname hello 2>/dev/null
./HEllO
./Hello
./hello

as root run 'updatedb'

when the process is finished, and you are looking for file 'gobbledigook' run

Code:

locate gobbledigook

Done.

updatedb runs as a cron job and executes every day at 10 PM.

locate, of course! I should have thought of that. It's not installed by default by all distributions. On SUSE distros it's in the package findutils-locate.

You need to use the -i option to get a case insensitive search.

Code:

locate -i gobbledigook

It might run at 10PM on your machine, that doesn't mean it runs at 10PM on all Linux machines. It probably will be run at least once a day, but when it runs will vary depending on the Linux distribution being used.

Hey thanks for that. I'm using locate so long now that I never came to reading the man pages...

True. I was not completely clear there. On my slackware systems it is installed by default. I put it in crontab to run at 10 PM, that being a time the machine will be running in the majority of times.
