A simple script to cache TLDR Node.JS client output to improve performance

tldr.sh

Generally each command takes ~500ms, but with this, they will take ~10ms to execute. Add this into shell profile page

function tldr () {
    mkdir -p /tmp/tldr_cache

    if [ "--flush-cache" == $1 ]; then
        rm /tmp/tldr_cache/*
        return
    fi

    if [ "--" == "${1:0:2}" ]; then
        command tldr $*
        if [ "--help" = $1 ]; then
            echo -e "To flush the custom caching\n"
            echo -e "    $ tldr --flush-cache"
        fi
        return
    fi

    if [ -f "/tmp/tldr_cache/$1" ]; then
        cat /tmp/tldr_cache/$1
    else
        script -q -c "tldr $1" /tmp/tldr_cache/$1
        sed '1d' /tmp/tldr_cache/$1 > /tmp/tldr_cache/$1.tmp;
        mv /tmp/tldr_cache/$1.tmp /tmp/tldr_cache/$1
    fi
