cat question
hello! why this works?

Code:
cd /home/user
cat * | ecasound -i stdin -o jack

and this doesn't?

Code:
cd /home/user/somedirectory
cat * | ecasound -i stdin -o jack

somedirectory are full with exe files which are the best source for this sort of noise thing

Unless you define what "doesn't work" means, it's possible that no one can help you.

cat * will exapnd to cat file1 file2... file1, file2 etc files being in the current directory. So chances are there that the "somedirectory" is empty!

i mean first example "cat's" files in my home directory to my soundcard and makes noise but second example throws error
cat: invalid option -- ' '
so how to use subfolder in home directory and cat all files from that directory to | ecasound -i stdin -o jack?

Perhaps you have a file name '-- '?

Code:
$ touch -- '-- '
$ cat *
cat: unrecognized option `-- '
Try `cat --help' for more information.
