我最近开始学习 linux，因为接下来几个月就要举办 ctf 比赛了。我遇到的问题是我试图制作一个从目录开始的 bash 脚本，检查内容是目录还是其他类型的文件。如果它是一个文件，图像等应用 strings $f | grep -i 'abcdef'，如果它是目录 cd 到该目录并重新开始。我有 C++ 经验，我理解其中的逻辑，但我无法真正让它发挥作用。我无法成功实现遍历所有子目录的循环。我们将不胜感激!
最佳答案
这个实现不需要循环。 find命令可以做你正在寻找的事情。 例如:
find /home -type f -exec sh -c " strings {} | grep abcd " \;
解释:
/home 是你的基本目录，可以是任何东西
-type f:表示普通文件
-exec 来自手册页:
"Execute command; true if 0 status is returned. All following arguments to find are taken to be arguments to the command until an argument consisting of
;' is encountered. The string{}' is replaced by the current file name being processed everywhere it occurs in the arguments to the command, not just in arguments where it is alone, as in some versions of find. Both of these constructions might need to be escaped (with a `') or quoted to protect them from expansion by the shell. See the EXAMPLES section for examples of the use of the -exec option. The specified command is run once for each matched file. The command is executed in the starting directory. There are unavoidable security problems surrounding use of the -exec action; you should use the -execdir option instead."
