bash: rt: 未找到命令... (profile中没有 “tr”)

linux执行 “source /etc/profile” 时提示
“bash: rt: 未找到命令... 相似命令是: 'tr' ” 但是在profile中找了半天没发现“tr”,下面是源码 ,请哪位大神帮忙看看!!!万分感谢~~

# /etc/profile


# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

这里的脚本 可能带了rt 命令 去看看 ,也只有这里有可能有了

多谢老铁,我也是找了所有的,最后在redis.sh上找到的
