$：命令未找到错误
在开放式终端上它显示在顶部
$: command not found $: command not found $: command not found yogesh@yogesh-WNB8PHF4710C-0030:~$ 和我的.bashrc文件有

这不是一个完整的答案。 我会发表评论，但这太浪漫了。
在评论中，您提到您将回声放入.bashrc中以找出问题所在。 如果我理解正确，你有这样的事情：
echo 1 if [ -f ~/.bash_aliases ]; then . ~/.bash_aliases fi echo 2
而对于输出，你得到了
1 $: command not found $: command not found $: command not found 2 yogesh@yogesh-WNB8PHF4710C-0030:~$
如果这是正确的，请在终端中运行此命令，并将输出编辑到您的问题中。
if [ -f ~/.bash_aliases ]; then echo "~/.bash_aliases exists." echo ls -l ~/.bash_aliases echo cat ~/.bash_aliases echo source ~/.bash_aliases else echo "~/.bash_aliases does not exist." fi
其中一个原因可能是“dos”行的结尾或者：
“＃： 没有找到指令”
a）在Krusader中打开〜.bashrc
b）在Krusader的菜单中，额外开启：“添加字节顺序标记（BOM）”
c）在.bashrc文件的第一行写“＃”
d）保存文件
e）运行ctrl + alt + T – lxterminal
f）你会得到：
＃：Befehl nicht gefunden。
要么
＃： 没有找到指令
如果你把“echo”放在.bashrc文件的第一行，那么你得到：
“Der Befehl»echo«wurde nicht gefunden，meinten Sie vielleicht：
Befehl»aecho«aus dem Paket»netatalk«（宇宙）
Befehl»echo«aus dem Paket»coreutils«（主要）
回声：Befehl nicht gefunden。“
等等。
如果您在Krusader的菜单中关闭额外function：“添加字节订单标记（BOM）”
然后在文件“.bashrc”的第一行输入“＃”或“echo”
“＃：command not found”错误消失了。
因此请注意您已关闭“添加字节订单标记（BOM）”
