I tried finding some files (*.e*) that are in the same directory as another file (md.tpr). I needed to list them (for further processing) using the following:

find . -name md.tpr -execdir ls *.e* \;

I tried a few variants of this command and some others (including single quoting the command passed to -execdir or passing it as sh -c 'ls *.e*' or eval 'ls *.e*' to name a few). It appears that globbing is not working when passed to -exec or -execdir. The error I get when running the above command is:

ls: *.e*: No such file or directory

Just as a sanity check, I did -execdir pwd and it prints what it should, so it appears that it's a problem with globbing, as those *.e* files do exist in the directories listed with this test.

Now, I was able to solve this problem in a much less elegant way but it just baffled me why globbing and wildcards wouldn't work here. Any ideas? Or am I completely off the track?

I use bash 3.2.25 (old but I don't have admin rights on that system).

Also, interestingly, if I do

find ~ -name .bashrc -maxdepth 2 -execdir ls -d .b* \;

it doesn't work unless it's done from $HOME.

Using find to ls seems a bit redundant, and I hope you were careful if you tried to parse the output. – jw013 Nov 9 '12 at 21:46
Yes, I am not worried about any unexpected characters in file names, so I wasn't bothered about the ls. The point was to find some files that live in the same file as another file (and then process them further). – Wojtek Rzepala Nov 9 '12 at 23:09

The shell does globbing, not find. When you type a command that includes an unquoted glob like .b* or *.e*, the shell will expand that for you. This happens before find ever sees it.

You probably have files like .bashrc, .bash_history, etc. in your $HOME directory. So when run from $HOME, your command turns into find ... -execdir ls -d .bashrc .bash_history ... \;. When run from other places, the .b* glob doesn't match anything, so it gets passed through. This still doesn't work, as it is the shell that does globbing, not find -exec. If you wanted the glob to be expanded for the -exec, you would need to invoke a shell to do it:

find ... -execdir sh -c 'echo globs: *' \;

Yes, true. I guess I'm baffled about the behaviour because doing things like find ... -name '*.txt' works (yes, yes, single quotes) and handles those globs properly, but when I pass such globs to -exec[dir], it fails. I made a comment in my post about single quotes and no quotes as at some point I did try everything, so dropping the quotes was the first thing I did, trying to figure out why things failed. The last example was to show that even the obvious thing didn't work (yes, I was expecting to see .bashrc, .bash_history, etc.). – Wojtek Rzepala Nov 9 '12 at 23:12
@WojtekRzepala -exec and -name work differently. -name does support globs. – jw013 Nov 10 '12 at 0:00
