not worry you cat a dir

alias_cat_cd_clear.sh

# Author: Esonhugh

# 
# c is an alias for clear cd and cat
# c with no param will clear
# c with one param(file) will like a cat a file
# c with one param(dir) will like cd into dir
# experimental: if c has more params will cat this all like cat command (finished)
# logic is 
# 1. clear and cd doesn't have second param. if second param exists must cat 
# 2. if 1 is False, Conditions are param number is 1 or 0.
# 3. in condition (param num is 0)clear has no param just clear the screen in terminal
# 4. test the param 1 is file or dictionary
# 5. dic is cd
# 6. file is cat

function c () {
        if [ -n "$2" ]
        then
                \cat $*
        elif [ -z "$1" ]
        then
                \clear
        else
                if [ -f "$1" ]
                then
                        \cat "$1"
                elif [ -d "$1" ]
                then
                        \cd "$1"
                else
                        echo "\033[1m   $1\033[0m is error name to file or dir"
                fi
        fi
}
