lookup name
cd name |
| | Find name in the current directory and make its inode the current inode. Name may be a multi-component name or may begin with slash to indicate that the root inode should be used to start the lookup. If some component along the pathname is not found, the last valid directory encountered is left as the active inode. This command is valid only if the starting inode is a directory. |
active
print |
| | Print out the active inode. |
| blocks |
| | Print out the block list of the active inode. Note that the printout can become long for large files, since all indirect block pointers will also be printed. |
| uplink |
| | Increment the active inode’s link count. |
| downlink |
| | Decrement the active inode’s link count. |
| linkcount number |
| | Set the active inode’s link count to number. |
| ls | List the current inode’s directory entries. This command is valid only if the current inode is a directory. |
rm name
del name |

| chinum dirslot inum |
| | Change the i-number in directory entry dirslot to inum. |

| chtype type |
| | Change the type of the current inode to type. Type may be one of: file, dir, socket, or fifo. |
