How to gain Write-Access to a File System as Root


I am trying to get change a script in a directory of a Linux derivat. I am logged in over root. The directory /opt/... seems to be write locked, I cannot create or change files. What I need to do to get write access??

Thanks and Regards
Tobias

Hi tobiasw,

can you post the output of
ls -la in that directory,

If it is r-x r-x r-x you will have to enter

chmod -R 700 dirname

If you see something like t in the list you will have to:-

chmod -t filename


Hope this helps you,


Aniruddha

...or it could be the filesystem itself. To see if you have any readonly filesystems mounted, try this command:

Code:
mount |grep '(.*ro.*)'
If you have a readonly-mounted device on which you wish to modify a file, you can remount it readwrite like this:

Code:
mount -o remount,rw /mount/point
Of course, this won't work if the readonly-ness of it is from the filesystem type (e.g. a CDROM or a squashfs filesystem image).

How to access an iso image.

Nice thing about unix (Linux) is that all the tools are available to do what you want.
Try this:
# mount -o loop file_name.iso /mnt

No need to copy files ie: dd etc...

Now you can see that the iso image is now mounted just like all other partitions by a df command.
