We can use echo $PS1 to view
test#testauto:~$ echo $PS1
\[\e]0;\u#\h: \w\a\]${debian_chroot:+($debian_chroot)}\u#\h:\w\$
test#testauto:~$
But what I want is "test#testauto:~$" not "[\e]0;\u#\h: \w\a]${debian_chroot:+($debian_chroot)}\u#\h:\w$"
How can I get it?
For Bash
echo "${PS1#P}"
For ZSH
echo "${(%%)PS1}"

Is there a easy way to list all open named pipes on linux? O a bash command to show all open named pipes?
An option: you can use the lsof command line tool: https://www.simplehelp.net/2010/04/09/how-to-get-a-list-of-open-files-sockets-and-pipes-in-linux/

When I was setting up my Ubuntu environment, I think I mistyped and did something like this:
echo 'srouce /opt/whatever'
And now when I open terminal, the first line is always:
srouce: command not found

Fix the misspelling in your shell startup files:
sed -i 's/srouce/source/' .bashrc .profile

Error when running this command, i think the command is clear to get the idea.
cp file.txt /folder/*/*/*/file.txt
You need a loop to do that:
for dir in /folder/*/*/*/; do cp file.txt "$dir"; done

alias bp="cat $# > $#.BACK"
My second idea was:
alias bp="cp $#{,.BACK}"
So i want to have a command to backup a file.
It does not raise any error but it simply doesn't work.
Aliases are purely a textual replacement. If you want to use or manipulate the arguments, you need to create a function:
bp () {
for file; do
cp -i "$file" "$file".BACK
done
}
