Oracle sqlplus in Linux cannot be used properly.

When Oracle sqlplus is used in linux, the arrow keys do not move the cursor left or right by default, and the commands are up and down. Therefore, if you want to execute the commands that have already been executed

When Oracle sqlplus is used in linux, the arrow keys do not move the cursor left or right by default, and the commands are up and down. Therefore, if you want to execute the commands that have already been executed, you should try again or use the CV method of other terminal tools. To modify a command, you only need to use the edit command to call vi or another editor, and then save it to a buffer file (the default file name is afiedt. buf) for execution. In short, it is inconvenient.

Rlwrap, a small tool, is a "readline wrapper" tool. You can use the left and right arrows to move the cursor between the left and right sides of a row, and use the up and down arrows to flip up and down the callback command, very easy to use. I use the 0.24 source code version. Installation and Simplicity:

./Configure

Make

Make install

For other installation situations, such as non-root installation, you can check the readme and install files, which is also very simple. And now there is an rpm version. After installation, add two sentences to the. bash_profile file of the Oracle user:

Alias sqlplus = "rlwrap sqlplus"

Alias rman = "rlwrap rman"

Log on to Oracle again or execute./home/oracle/. bash_profile to make the change take effect. The arrow keys can be used as expected in sqlplus and rman.

Run the "du-sh" command to view the folder size.
