Install install or upgrade software or backup data

Add that the install command is similar to the cp command in that you can copy files / directories to a specified location. However, install allows you to control the properties of the target file. Install is usually used for the makefile of a program and is used to copy the program to the target (installation) directory.

Syntax install [OPTION]... [- T] SOURCE DEST install [OPTION]... SOURCE... DIRECTORY install [OPTION]... -t DIRECTORY SOURCE... Install [OPTION]... -d DIRECTORY... In the first two formats, multiple files are copied to or to existing ones, and the permission mode and owner / group are set. In the third format, all specified directories and their home directories are created. The parameters that the long option must use are also necessary when using the short option.

Option-- backup [= CONTROL]: back up each existing destination file. -b: similar to-- backup, but does not accept any parameters. -c: (this option is not processed). All parameters are treated as directories, and all home directories of the specified directory are created. -D: all home directories before creation, and then will be copied to; useful in the first use format. -GMAT talk group = group: set the group to which you belong, rather than the group to which the process currently belongs. -mmam talk mode = mode: set your own permission mode (like chmod) instead of rwxr-xr-x. Owner: set the owner by yourself (for superusers only). -pmam talk about the visit / modification time of the file as the time attribute of the corresponding destination file. -smam copyright strip: use the strip command to delete symbol table, which is only applicable to the first and second formats. -Smam copyright suffix = suffix: the backup file is specified by yourself. -vmam Meltel verbose: print the name when processing each file / directory. -- help: display this help and leave. -- version: displays the version information and leaves. Instance install-d [option] DIRECTORY [DIRECTORY...] Support multiple, similar to mkdir-p support recursion. For example, the result of install-d a/b/c e _ bind f is the same as that of mkdir-p a/b/c e _ hand f.

Install [option] SOURCE DEST copy the SOURCE file (the test cannot be a directory) to DEST file (file):

The result of install a _ d _ e c is similar: cp a _ r _ e c # Note that c must be a file. Useful options-D:

The effect of install-D x a/b/c is similar: mkdir-p an a/b/c install b & & cp x a/b/c install [option] SOURCE [SOURCE...] DIRECTORY copies multiple SOURCE files to the destination directory:

Install a _ b * d, where d is the directory.
