Linux sticky bit and stickybit

Only the root or owner can delete or rename the file when setting the stick position.

 

Example:

The default apple group is fruit.

[Root @ titan ~] # Id apple

Uid = 1001 (apple) gid = 1001 (fruit) group = 1001 (fruit)

 

Step 1 shows the water Folder Information, which is not currently set with a sticking bit.

[Root @ titan/] # ls-l | grep water

Drwxr-xrwx. 4 root 4096 August 10 21:02 water

 

Step 2 shows the water subfolders.

[Root @ titan/] # ls-l water

Total usage 8

Drwxr-xr-x. 2 root 4096 August 10 21:02 mineral

Drwxr-xr-x. 2 root 4096 August 10 21:02 pure

 

Step 3 Delete the mineral folder.

[Apple @ titan water] $ rm-r mineral/

Rm: Do you want to delete the write-protected directory 'Mineral /'? Y

 

Step 4: display the water subfolders.

[Apple @ titan water] $ ls-l

Total usage 4

Drwxr-xr-x. 2 root 4096 August 10 21:02 pure

 

Step 5 set the adhesion bit for the water folder.

[Root @ titan/] # chmod o + t water

[Root @ titan/] # ls-l | grep water

Drwxr-xrwt. 3 root 4096 August 10 21:08 water

 

Step 6 Delete the pure folder as an apple user.

[Apple @ titan water] $ rm-r pure

Rm: Do you want to delete the write-protected directory 'pure '? Y

Rm: Unable to delete 'pure ': Operation not permitted

 

Step 7 delete the pure folder as the root user.

[Root @ titan water] # rm-r pure/

Rm: Do you want to delete the 'ure/'directory /'? Y

 

Step 8 shows the water subfolders.

[Root @ titan water] # ls-l
