INSTALL(1) User Commands INSTALL(1) NAME install - copy files and set attributes SYNOPSIS install [OPTION]... [-T] SOURCE DEST install [OPTION]... SOURCE... DIRECTORY install [OPTION]... -t DIRECTORY SOURCE... install [OPTION]... -d DIRECTORY... DESCRIPTION This install program copies files (often just compiled) into destina‐ tion locations you choose. If you want to download and install a ready-to-use package on a GNU/Linux system, you should instead be using a package manager like yum(1) or apt-get(1). In the first three forms, copy SOURCE to DEST or multiple SOURCE(s) to the existing DIRECTORY, while setting permission modes and owner/group. In the 4th form, 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 -b like --backup but does not accept an argument -c (ignored) -C, --compare compare content of source and destination files, and if no change to content, ownership, and permissions, do not modify the destination at all -d, --directory treat all arguments as directory names; create all components of the specified directories -D create all leading components of DEST except the last, or all components of --target-directory, then copy SOURCE to DEST --debug explain how a file is copied. Implies -v -g, --group=GROUP set group ownership, instead of process' current group -m, --mode=MODE set permission mode (as in chmod), instead of rwxr-xr-x -o, --owner=OWNER set ownership (super-user only) -p, --preserve-timestamps apply access/modification times of SOURCE files to corresponding destination files -s, --strip strip symbol tables --strip-program=PROGRAM program used to strip binaries -S, --suffix=SUFFIX override the usual backup suffix -t, --target-directory=DIRECTORY copy all SOURCE arguments into DIRECTORY -T, --no-target-directory treat DEST as a normal file -v, --verbose print the name of each created file or directory --preserve-context preserve SELinux security context -Z set SELinux security context of destination file and each cre‐ ated directory to default type --context[=CTX] like -Z, or if CTX is specified then set the SELinux or SMACK security context to CTX --help display this help and exit --version output version information and exit The backup suffix is '~', unless set with --suffix or SIM‐ PLE_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 AUTHOR Written by David MacKenzie.
