Directory Structure in AIX
AIX uses the same file and directory structures as other UNIX operating systems. The structures are called file trees. In a file tree, directories are root nodes, which orderly organize data and programs in groups. Files are leaf nodes owned by directories.
Table 2-1 describes the commonly used directories in AIX.
Directory |
Description |
|---|---|
/ |

/etc |

/dev |

/home |
Root directory that stores all accounts except account root. |
/u |
Link directory that navigates to /home. |
/tmp |
Stores temporary files created by users or the system. |
/usr |
Stores AIX operation commands, databases, and other applications. |
/var |
Stores system operation logs. |
/opt |
Used for installing common application systems. |
/admin |

/sbin |
Stores commands and scripts that are important for file system /usr and system startup. |
/lost+found |
