Linux / Unix Commandinstall


ginstall - copy files and set attributes  


install [OPTION]... SOURCE DEST (1st format) 
install [OPTION]... SOURCE... DIRECTORY (2nd format) 
install -d [OPTION]... DIRECTORY... (3rd format)  


In the first two formats, copy SOURCE to DEST or multiple SOURCE(s) to the existing DIRECTORY, while setting permission modes and owner/group. In the third format, create all components of the given DIRECTORY(ies).

Mandatory arguments to long options are mandatory for short options too.

--backup[=CONTROL] make a backup of each existing destination file


like --backup but does not accept an argument




Install file, unless target already exists and is the same as the new file, in which case the modification time won't be changed.


treat all arguments as directory names; create all components of the specified directories


create all leading components of DEST except the last, then copy SOURCE to DEST; useful in the 1st format


set group ownership, instead of process' current group


set permission mode (as in chmod), instead of rwxr-xr-x


set ownership (super-user only)


apply access/modification times of SOURCE files to corresponding destination files


strip symbol tables, only for 1st and 2nd formats

-S--suffix=SUFFIX override the usual backup suffix


print the name of each directory as it is created


display this help and exit


output version information and exit

The backup suffix is `~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX. The version control method may be selected via the --backup option or through the VERSION_CONTROL environment variable.

Here are the values:

none, off

never make backups (even if --backup is given)

numbered, t

make numbered backups

existing, nil

numbered if numbered backups exist, simple otherwise

simple, never

always make simple backups


The full documentation for install is maintained as a Texinfo manual. If the info and installprograms are properly installed at your site, the command

info install

should give you access to the complete manual.

Important: Use the man command (% man) to see how a command is used on your particular computer.
