我如何从另一个目录访问目录中的文件（linux）

Question

im trying to change permissions on a txt file founded in directory X While im in the directory Y

  kosay_sabbah@DESKTOP-87R0T4M:~/Kosay/grp2$ chmod 777 3.txt

  chmod: cannot access '3.txt': No such file or directory

Answer 1

You should use absolute or relative file path. For example you have file1.txt in directory /directory1/ - absolute file path is /directory1/file1.txt . If your current path is /directory2/ , you can run chmod for file1.txt in two ways:

1. Using relative path - chmod../directory1/file1.txt

2. Using absolute path - chmod /directory1/file1.txt
