(Solved) How to use tmpfs for /tmp?

[zhangyou]

I notice that there is a tmp folder in my home folder, which is ~/tmp. Apparently it is functioned as the /tmp in other distros. Now I want to move it to RAM so that I can get more use of my 4GB RAM and clean the content in there every reboot.

I already added a line of tmpfs /dev/shm tmpfs defaults 0 0 in /etc/fstab according to my previous Bodacious Bacon setting but it doesn't help.

I tried to create a link of ~/tmp to /tmp, but there is already a folder named tmp in home folder so never succeeded.

What should I do?

Many of us have /tmp in RAM. So if ~/tmp is a link to /tmp, both /tmp and ~/tmp will be in RAM.

To get /tmp into ram you need the line

Code: [Select]

none /tmp tmpfs defaults 0 0in /etc/fstab. Its created automatically if you check "Clean /tmp at each boot" in PCC.

If you add it manually, remember to empty /tmp before you reboot (or everything in /tmp will remain on your hard drive but hidden under the tmp in RAM).

If you wish to make ~/tmp a symbolic link to /tmp, first check that it isn't a link already; if it isn't, remove your existing ~/tmp and, as your normal user, create the link with the command

Code: [Select]

ln -s /tmp ~/tmpor by drag and drop in Konqueror or Dolphin.

Thanks Bald Brick
the ~/tmp is a folder not a link. so every time i delete it, it is automatically created again in no time. therefore it is impossible to create a link named tmp in home folder.

You could try doing it from outside KDE, e.g. from a tty. Hold down Ctrl and Alt and hit F1; then log in as your normal user and enter

Code: [Select]

rm -rf ~/tmp && ln -s /tmp ~/tmp
(But remember that rm with the options -r and -f is dangerous.)

Edit:

Ctrl+Alt+F8 should give you your desktop back. If ~/tmp is still recreated too fast, log out of KDE and start a terminal session as your normal user.

Edit 2:

I was just able to create ~/tmp as a link to /tmp by running

Code: [Select]

rm -rf ~/tmp && ln -s /tmp ~/tmpin Konsole, i.e. from within KDE. Even if ~/tmp is recreated fast and automatically these days, it wasn't fast enough....

The command of

Code: [Select]

rm -rf ~/tmp && ln -s /tmp ~/tmp however didn't work. But I managed to make it work by using:

Code: [Select]

rm -rf tmp && ln -s /tmp tmp when opening a konsole in home folder.

Thanks very very much!!!

I wonder why not. Bash does normally understand "~" to mean the user's home directory. (That's why I told you to run the command as your normal user. If you did, "~" should have been interpreted as "/home/<user>". If you run the command as root, "~" just means "/root".)

But I managed to make it work by using:

Code: [Select]

rm -rf tmp && ln -s /tmp tmp when opening a konsole in home folder.

That's the main thing. (But then you must have run the command from within /home/<user>, or it wouldn't have worked....)

Thanks very very much!!!

You are very welcome.
