Dynamic prompt line

Two lines to put on your .bashrc file to have a nice dynamic prompt line.

export MAX_PATH_LENGTH=25

export PROMPT_COMMAND='PS1="\\[\\033[32m\\][\u@\h:\`if [[ \$? = "0" ]]; then echo "\\[\\033[35m\\]"; else echo "\\[\\033[31m\\]"; fi\` \`if [[ `pwd|wc -c|tr -d " "` > $MAX_PATH_LENGTH ]]; then echo "\\W"; else echo "\\w"; fi\`\\[\\033[32m\\]]\$\[\033[0m\] "; echo -ne "\033]0;`hostname -s`:`pwd`\007"'

NB : The color of the path change if the last command written is unknown or wrong, and shortens for long directories path.

[Vim] highlight a search or not, that is the question

As default, when you make a search, Vim highlight the result.
This option can sometimes be irritating, especialy when you search "=" or "," characters.

So, here is a line to put on your .vimrc (Vim default configuration file) :
noremap ‹F7› :set hls!‹cr›:set hls?‹cr›
So now, with the [F7] key you can highlight or not a search result. Usefull, isn't it?
