Unable to run files with 700-777 permissions
I finally installed Chakra Linux and noticed whether I create or extract a file with 700, 755, 775 permissions a * sign is listed at the end of the filename:
Code:
[user@mybox bitcoin-0.8.6-linux]$ ls -l bin/32 
total 16440 
-rwxr-xr-x 1 501 utmp  6321496 09.12.2013 04:02 bitcoind* 
-rwxr-xr-x 1 501 utmp 10508613 09.12.2013 04:02 bitcoin-qt*

When I try to run these files I get an error that they do not exist:

Code:
[user@mybox bitcoin-0.8.6-linux]$ bin/32/bitcoin-qt  
bash: bin/32/bitcoin-qt: No such file or directory  

[user@mybox bitcoin-0.8.6-linux]$ bin/32/bitcoin-qt* 
bash: bin/32/bitcoin-qt: No such file or directory

I even tried using an escape, but no such luck:

Code:
[user@mybox bitcoin-0.8.6-linux]$ bin/32/bitcoin-qt\*  
bash: bin/32/bitcoin-qt*: No such file or directory

Any suggestions?

Read your error report...
You need the absolute path...
Code:
/bin/32/bitcoin-qt*

EDIT:
OR...
Code:
/full/path/to/bin/32/bitcoin-qt*

NOTE:
On CygWin a file with a star at the end can exist and be part of that filename.
However you may be using an alias for ls that is doing the same as ls -lF...

The * is probably not part of the filename.

It does not know where to find the file, because it does not search from the current path for security reasons.

To tell it to search from the current path, prefix the filename with ./

like ./path/to/file

The original ls is using a relative path. Using the absolute path you suggest will lead to a different directory if the current working directory of the relative path is anything other than /.

This is not a PATH issue, since PATH is not used when the command name contains slashes.

To the OP:

To exec a file, not only must it have the executable mode/permissions bit set, but so must all of the directories leading to it. Have you confirmed that bin, bin/32, and the directory components leading to the the current working directory (inclusive) all have the execute bit enabled?

Also, "no such file or directory" can sometimes mean "can't find all the libraries it needs" or "wrong file type", so ldd executablename and see if anything's missing.
