First of all as others already saied: HISTCONTROL=ignoredups
...and then maybe a script like:
----8<------------------------------------------------------------------
#!/bin/bash
if [ ! -f ~/.bash_history.lock ] ; then
echo -n "Please wait, eleminating dups in the ~/.bash_history... "
touch ~/.bash_history.lock
if [ -f ~/.bash_history ] ; then
touch ~/.bash_history.tmp
(cat ~/.bash_history) |
while read LINE
do
if [ -z "$(grep "${LINE}" ~/.bash_history.tmp)" ] ; then
echo -e "${LINE}" >>~/.bash_history.tmp
fi
done
mv --force ~/.bash_history.tmp ~/.bash_history
fi
rm --force ~/.bash_history.lock
LINES=$(cat ~/.bash_history |wc --lines)
echo "${LINES} lines currently."
fi
