[SOLVED] Cannot Modify Folder Created By Program And Not By Me

hitmen · 11-12-2011, 11:48 AM

Basically I used photorec to rescue my photos.
However, the program created a locked folder and I cant change the photos inside.

sudo chmod +x [folder name] does not help since I the user did not create the folder.

Help!

Have you tried chowning the file to you?

edit: P.S. Why are you trying to make a directory executable?

hitmen · 11-12-2011, 11:59 AM

I am trying to make the files executable. I made the folder executable by mistake.

How do you chown?

Also, what is my root password? I tried su but i dont know the passwd

You are almost certainly going to need it. A list of pages about doing so here.

First do 'sudo bash' to become an elevated user.
Then when you do 'id' it should show say "uid=0(root) gid=0(root) groups=0(root)" or something to ensure you're a root user. That will allow you to chown c *.jpg. Just be sure to be in the directory with the jpg files

ok done. Now how do I go back in user mode?

hitmen · 11-12-2011, 11:27 PM

up. How do I go back to user mode, (other than restarting).

What is the diff between sudo bash and su?

fukawi1 · 11-12-2011, 11:31 PM

Code:

exit

man su

Code:

DESCRIPTION
       The su command is used to become another user during a login session.
       Invoked without a username, su defaults to becoming the superuser. The
       optional argument - may be used to provide an environment similar to
       what the user would expect had the user logged in directly.

man sudo

Code:

DESCRIPTION
       sudo allows a permitted user to execute a command as the superuser or
       another user, as specified in the sudoers file.

They sound about the same to me.
Is a superuser also known as root? What is the difference ?

chrism01 · 12-19-2011, 11:09 PM

superuser = root (this is the real admin's username; see first entry in /etc/passwd)

Code:

su = switch user
#As above, by default it switches you to root unless you specify otherwise
#http://linux.die.net/man/1/su

su <someuser>

note as above that this will switch user, but leave you with your original env. To get the target user's env, add '-' thus

Code:

# to root
su - 

# to otheruser
su - newuser

sudo http://linux.die.net/man/8/sudo temporarily enables you as a target user as allowed by the sudoers file http://linux.die.net/man/5/sudoers & limited to the cmds defined therein.
