[SOLVED] Exact same 'find' command works then doesn't

lucmove · 04-09-2022, 08:39 PM

I want to get the md5 hash of all files in a directory:

Code:

$ find ./ -type f -exec md5sum {} \; > ./md5.txt

Note: my shell is Fish.

That works on a Debian 10 machine. I just tested. It works.

But it doesn't work on a Debian 9 machine.

There are 14 files in the directory. Here is the output:

Code:

$ find ./ -type f -exec md5sum {} \; > ./md5.txt
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory
md5sum: '': No such file or directory

What is going on?

Probably has something to do with this:

Different versions of fish between debian 9 and 10 treat {} differently? Who knows. Try escaping the \{.

Well, that's embarrassing. I've been using Fish for some 10 years and I didn't realize curly brackets had special meaning. I grep'ped my old scripts and found that I use them very rarily, almost invariably in regex. I see I need to brush up on my fishing skills.

Thank you.

Yeah, most of us don't go fishing, we just bash things around.
