RLWRAP

rlwrap.sh

# Basic usage: Tell iex to write all history to 
# rlwrap -a iex # --always-readline

# Full working script:

# Increment the file name with the session pattern. based on what files currently exist:
rlwrapVersion=$(ls $HOME/.$filePrefix* | wc -l | awk '{print 0$1 + 1}');

# This is the path we will be writing to:
rlwrapTempPath="$HOME"/."$filePrefix"_"$rlwrapVersion"_history;
echo $rlwrapTempPath;

# Run rlwrap on iex with appropriate commands:
filePrefix=iex; rlwrap -a --history-filename="$rlwrapTempPath" "$filePrefix";

# Check after the session that everything worked:
# vi "$rlwrapTempPath";

# Other cleanup commands
echo $HOME/.iex_*
ls $HOME/.iex_*
rm -rf $HOME/.iex_*
