bash: if export PROMPT_COMMAND then remove rm $( ls -t | head -1) is not working

Question

Below function name will set the the current working directory name as tab name using function myfunc but if I pass argument to name then it will set tab name to passed argument.
for e.g.
name mytab [----> this will set the current tab name to mytab]

my bashrc is as follows :

function myfunc {  
echo -n -e "\033]0;${PWD##*/}\007" 
#--- some other thing ---
} 
function name {  
    if [ "$1" ]  
    then  
        unset PROMPT_COMMAND  
        echo -ne "\033]0;${*}\007"  
    else  
        unset PROMPT_COMMAND  
        export PROMPT_COMMAND="history -n; history -w; history -c; history -r; myfunc;$PROMPT_COMMAND"  
    fi  
}  
name

So if I execute rm $(ls -t | head -1)
I am getting error as /bin/rm: cannot lstat `\033[0m\033[0mReadme.txt\033[0m': No such file or directory

can you show the output of `which ls` – shafeeq Apr 25 '16 at 11:36 — shafeeq, Apr 25 '16 at 11:36
`which ls` >> `alias ls='ls --color'` `/bin/ls` – ypp Apr 25 '16 at 11:57 — ypp, Apr 25 '16 at 11:57
can you test the command `rm $(ls --color=no -t | head -1)` – shafeeq Apr 25 '16 at 12:01 — shafeeq, Apr 25 '16 at 12:01

Please use the following command

rm $(ls --color=no -t | head -1)

This outputs the result of ls without colors in it, which is what makes your Readme.txt to be shown, instead, as \033[0m\033[0mReadme.txt\033[0m.

Alternatively, you can circumvent the alias of ls by saying \ls --> \ls -t | head -1. More info in Why start a shell command with a backslash?.

Yes, worked gr8. I just changed it to `rm $(/bin/ls -t | head -1)` – ypp Apr 25 '16 at 13:49
