如何覆盖现有的 .rar 档案？

如何添加文件.txt到现存的档案拱形，但在某种程度上拱形将仅包含文件.txt? 我使用下面的命令，但是拱形已更新，并且也包含旧文件。我没有看到可以执行此操作的开关。

rar a arch.rar file.txt

这没有任何意义；）但你可以做这样的事情：

$ FILE2UPD=file.2; RARCH=arch.rar && for i in `rar l $RARCH | grep -v $FILE2UPD | tail -n +9 | head -n -3 | cut -f2 -d' '`; do rar d $RARCH $i; done && rar u $RARCH $FILE2UPD

例子：

$ cat file.1
test 1
$ cat file.2
test 2
$ cat file.3
test 3
$ rar a arch.rar file.*
