Question

I have a Unix Aix Server which I log in.

When i try to create a file using touch filename.txt I get an error saying :

touch: 0652-046 Cannot create filename.txt

I have executed id and ls -lad . commands and posted the results:

Response of id : uid=290975(gaara) gid=10(audit)
Response of ls -lad . : drwxr-xr-x    2 sigadmin student  256 Jan 11 05:57 .

Answer 1

First, check file permissions.

ls -lad .

You’ll get a response like this:

drwxrwxr-x   2 user group 4096 Jan 11 11:26 .

Those permissions indicate rwx (user) rwx (group) and r-x (others). I.e only user and group can create files in this directory (w=write permission).

Compare these to you own UID/GIDs.

id

In your case the directory is owned by sigadmin. Group student and others have no permission to create in this directory (r-x). So it’s not supposed to work, since sigadmin is the only one having permissions to write in this directory.
