file permissions

Hi!

Is there any shell parameter that I can use in my script to check the file-permissions I have in the currect directory!?

The history behind is: My script tries to create some log files in the folder and I want to see whether I have enough permissions to do that. And exit in case I dont have.

currently I create a temp file using touch command, and check the return code ($?) of that command, and exit if it is non-zero, and remove the temp file if zero. This is a unwanted process!!

Thanks in advance,

Mohan. Smilie

You could use

Code:
stat -c=%a logfile

That would return something like

=600 which is equivalent to -rw-------

instead of creating a temp file --- create the logfile instead, check for it and exit your script if you can't create the logfile ...

echo > $logfile
[ ! -f $logfile ] && exit

Code:
$ mkdir tmpdir
$ ls -ld tmpdir
drwxr-xr-x 2 bozo bozogroup 0 May 31 23:02 tmpdir
$ [ -w "./tmpdir" ] && echo "Yes I can write..."
Yes I can write...
$ chmod 500 tmpdir             
$ ls -ld tmpdir
dr-x------ 2 bozo bozogroup 0 May 31 23:02 tmpdir
$ [ -w "./tmpdir" ] && echo "Yes I can write..."
$

Cheers
