Shell Script - Need to Understand

[Walidsi]

I am new to Linux and I need to understand what the following script does in details please. I totally do not understand steps 5 to 8. Thanks a million!!


AIX Team:
2.) Login to server and switch to root

3.) Create a new lv

smitty lv -> Add a Logical Volume -> choose rootvg ; lv name: versatalib_lv ; lv type: jfs2 ; Number of
logical partitions: 1

4.) Create a new fs

smitty fs -> Add File Systems -> Enhanced Journaled File systems -> Add an Enhanced Journaled File System on a Previously Defined Logical Volume -> lv name choose: versatalib_lv ; mount point: /usr/Versata/VLSComponents/Classes/RDWWPRT.ear/RDWWPRT.war/WEB-INF/lib ; Mount automatically at system restart: yes ; Permissions: read/write

5.) mount the newly created filesystem to another directory (ex.: /tmp/versata_lib)

6.) Copy the content of the lib directory to the new filesystem

cp -R /usr/Versata/VLSComponents/Classes/RDWWPRT.ear/RDWWPRT.war/WEB-INF/lib /tmp/versata_lib

7.)smitty fs -> change file systems -> Enhanced Journaled File systems -> Change Characteristics of an Enhaced Journaled File systems : choose the newly created fs -> switch Permissions to read-only

8.) mount up /usr/Versata/VLSComponents/Classes/RDWWPRT.ear/RDWWPRT.war/WEB-INF/lib
