os:rhel6.4

oracle:10.2.0.1

Because the oracle10g comes out for a long time, many 10g packages have been updated to the new version, so there are a lot of strange problems during the installation process.

For example, 64 requires a lot of 32-bit packages for the system, such as following the steps to complete the installation of the software process will still have

A Place not perfect

1, changing the way the file changes the kernel memory and resource limits, if the same environment in the repeated execution of this script, the contents of the file is duplicated.

Summarize the points of knowledge

1, the use of the SED flow editor

Delete match line sed/match content/d/tmp/ceshi.txt it only outputs the result and does not change the original file.

Replace the contents of the SED s/replaced content/replaced content/g/tmp/ceshi.txt it will replace all matching words nonalphanumeric, that is, the default global

-I saves the content in a file, such as sed/match content/d-i/tmp/ceshi.txt

2. grep matches multiple conditions

Grep-e ' a| b| C

3, mkdir already exists directory

If the directory already exists, the error will be directly.

Plus the parameter "-P" will not error, but the-p parameter to create the parent directory, using this parameter will not recreate the directory, that is, the files in the original directory will not be deleted.

4. Cut Command Review

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

5. Date Command Review

Date sets the time display format.
