rpm -qpl dhad-9.0.27891-2.x86_64.rpm允许显示此包的所有文件路径和目录路径。

我想要仅过滤文件路径

我尝试:

rpm -qpl dhad-9.0.27891-2.x86_64.rpm | find -type f

还 :

rpm -qpl dhad-9.0.27891-2.x86_64.rpm|grep -f

还 :

rpm -qpl dhad-9.0.27891-2.x86_64.rpm |ls -f

一切都没起作用。

答案1

那太糟糕了。不过,如果输出是这样排序的,我们可以反向查看它:

  1. 采取最后一行
  2. 删除最后一个之后的所有内容/并存储起来,然后转到下一行
  3. 如果没有等于最后一个目录名,打印
  4. 上移输出并返回步骤2。

为了保持顺序,我们还需要重新反转输出。幸运的是,有一个名为tac(的反转cat)的小命令可以简化这一过程。我们只需在 Bash 脚本之前和之后调用它即可:

... | tac | while read p; do [ "$l" != "$p" ] && echo "$p"; l="$(dirname "$p")"; done | tac

请注意,只有当我们能够依赖文件顺序时,这才会起作用。我想我们可能可以;我只见过像这样排序的包文件,所以我认为这是标准的。


当尝试回答这个问题时,我开始使用不同的方法awk。这些天我似乎以 -form 的形式给出了大部分答案,awk因此上面是 awk 看到的内容:

... | tac | awk 'l!=$0{print}{sub(/\/[^\/]*$/,"",$1);l=$0}' | tac

它稍微短了一点,但我怀疑它会更快。

答案2

README 和 LICENSE 似乎都是文件。因此你可以尝试,

rpm -qpl dhad-9.0.27891-2.x86_64.rpm | grep -P '.*\..*|README|LICENSE'

答案3

你需要测试我认为每个文件路径例如

some command \
| xargs -I{} sh -c 'test -f "$0" && printf "%s\n" "$0"' {}

或者

while read -r f; do 
  [[ -f "$f" ]] && printf "%s\n" "$f"
done < <(some command)
