Shell programming oracle10g installation preparations before rhel6.4, oracle10grhel6.4

OS: rhel6.4

Oracle: 10.2.0.1

Because oracle10g has been released for a long time and many packages used for 10g have been updated to a new version, many strange problems may occur during the installation process.

For example, 64 requires many 32-bit packages for the system. For example, after completing the following steps

Bug 8993720: error invoking target 'collector 'OF makefile' $ O_H/SYSMAN/LIB/INS_EMDB.MK'

But you can ignore it directly.

Incomplete

1. Change the number of kernel memory and resource limits by changing the file. If the script is repeatedly executed in the same environment, the file content is repeated.

Summarize the knowledge points

1. Use of sed stream Editor

Delete the sed/match content in the matched row/d/tmp/ceshi.txt. It only outputs the result and does not change the original file.

Replace sed s/replaced content/g/tmp/ceshi.txt, which replaces all matching characters, that is, the global

-I stores the content in the file, such as sed/matched content/d-I/tmp/ceshi.txt

2. grep matches multiple conditions.

Grep-E 'a | B | C'

3. The mkdir directory already exists.

If the directory already exists, an error is reported.

If the "-p" parameter is added, no error is reported. However, the "-p" parameter is used to create a parent directory. If this parameter is used, no directory is created again, that is, files in the original directory will not be deleted.

4. cut command review

Cut-d': '-f 2/tmp/123.txt

5. Review of the date command

Date sets the time display format.
