vcs 警告 egrep obsolescent

smhr

操作系统比较新
vcs2018.9 在仿真时提示警告：

1. egrep: warning: egrep is obsolescent; using grep -E
   
2. grep: warning: stray \ before -
   
3. egrep: warning: egrep is obsolescent; using grep -E
   
4. grep: warning: stray \ before -
   
5. /bin/grep: warning: stray \ before -
   
6. /bin/grep: warning: stray \ before -
   
7. /bin/grep: warning: stray \ before -

这应该是跟我的egrep grep 的版本有关系，但是这应该如何修改呢？有懂得大佬希望可以帮忙解决以下谢谢啦
使用的是 grep (GNU grep) 3.11

mv /usr/bin/egrep /usr/bin/egrep.backup
echo 'grep -E $@' > /usr/bin/egrep
chmod a+x /usr/bin/egrep

mv /usr/bin/egrep /usr/bin/egrep.backup
echo 'grep -E $@' > /usr/bin/egrep
chmod a+x /usr/bin/egrep ...

非常感谢，我看了一下我的egrep 里面已经跟您发的改得一样了，只是爆出了警告

1. #!/bin/sh
   
2. cmd=${0##*/}
   
3. echo "$cmd: warning: $cmd is obsolescent; using grep -E" >&2
   
4. exec grep -E "$@"
