Linux shell generally uses-f to determine whether the file exists;-d to determine the directory.

[[- f file name]] & & echo yes

If printing a yes indicates that the file can be detected by the current user

-e filename if filename exists, true-d filename if filename is directory, true-f filename if filename is regular file, true-L filename if filename is symbolic link, true-r filename if filename is readable, true-w filename if filename is writable, true-x filename if filename executable, true-s filename if file length is not 0, true-h filename if file is soft link

Common examples

If a file exists, delete it

If [- f trials]; then rm ${result_path} trials; fi

If there is no folder, create

If [!-d $result_name]; then mkdir-p $result_namefi on the method of judging the existence of files in the linux system is shared here. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
