+ 1] [4 + 0 + 1] [4 + 0 + 0] = 754. Therefore, you need to issue the command chmod 754 filename. The most common problem is that after we edit shell text files using vi, the attribute is usually-rw-, that is, the 666 attribute, if you want to change it to an executable file and do not want others to modify it, you need the 755 Attribute-rwxr-xr-x, so you need to use chmod 755 test. sh.In addition, some files do not want to be viewed by others, such as-rwxr --. Therefore, use the command chmod
