usage=“\ Usage: $0 [OPTION]… [-T] SRCFILE DSTFILE
or: $0 [OPTION]... SRCFILES... DIRECTORY or: $0 [OPTION]... -t DIRECTORY SRCFILES... or: $0 [OPTION]... -d DIRECTORIES...
In the 1st form, copy SRCFILE to DSTFILE. In the 2nd and 3rd, copy all SRCFILES to DIRECTORY. In the 4th, create DIRECTORIES.
Options:
--help display this help and exit. --version display version info and exit. -c (ignored) -C install only if different (preserve data modification time) -d create directories instead of installing files. -g GROUP $chgrpprog installed files to GROUP. -m MODE $chmodprog installed files to MODE. -o USER $chownprog installed files to USER. -p pass -p to $cpprog. -s $stripprog installed files. -S SUFFIX attempt to back up existing files, with suffix SUFFIX. -t DIRECTORY install into DIRECTORY. -T report an error if DSTFILE is a directory.
Environment variables override the default commands:
CHGRPPROG CHMODPROG CHOWNPROG CMPPROG CPPROG MKDIRPROG MVPROG RMPROG STRIPPROG
By default, rm is invoked with -f; when overridden with RMPROG, it’s up to you to specify -f if you want it.
If -S is not specified, no backups are attempted.
