Wrap Oracle SQL*Plus
One of the key problems with Oracle’s deployment is that you can not use the up-arrow key to navigate the sqlplus command-line history. Here’s little Bash shell function that you can put in your .bashrc file. It requires you to have your system administrator install the rlwrap package, which wraps the sqlplus command-line history.
You should also set the $ORACLE_HOME environment variable before you put this function in your .bashrc file.
sqlplus () { # Discover the fully qualified program name. path=`which rlwrap 2>/dev/null` file='' # Parse the program name from the path. if [ -n ${path} ]; then file=${path##/*/} fi; # Wrap when there is a file and it is rewrap. if [ -n ${file} ] && [[ ${file} = "rlwrap" ]]; then rlwrap sqlplus "${@}" else echo "Command-line history unavailable: Install the rlwrap package." $ORACLE_HOME/bin/sqlplus "${@}" fi } |
If you port this shell script to an environment where rlwrap is not installed, it simply prints the error message and advises you to install the rlwrap package.
As always, I hope this helps those looking for a solution.
