- NAME
- install - install files
- SYNOPSIS
- install [-lcszN] [-o owner] [-g group] [-m mode] [-S stack] [file1] file2
- install [-lcszN] [-o owner] [-g group] [-m mode] [-S stack] file ... dir
- install -d [-o owner] [-g group] [-m mode] directory
- DESCRIPTION
- Install puts executables, manual pages, and library files in their proper
- place in the bin, man, and lib directories. The first two forms of the
- command are like cp(1) copying either one file to another or copying
- several files to a directory. The "-d" form is like mkdir(1) with the -p
- flag. File1 may be omitted if neither -l nor -c is given to change the
- attributes of file2.
- Attributes are always copied from the source file, use the options to
- change. Note that the source file's attributes are changed with the
- destination file if they are linked. So copy the file if you change it
- in a way that makes it read-only. You would otherwise not be able to
- compile a command again.
- OPTIONS
- -l Link the destination to the source file instead of copying it. This
- is done to either save space on a file system with both the source
- and the bin directories on it, or to install synonyms to a command.
- -c Copy the source file to its proper place. This option is the
- default if -l is not given. With -l, the file is copied if the link
- fails.
- -s Strip the destination file of its symbol table, if it is an
- executable, and if it is actually copied. It has no effect on a
- link or a non-executable.
- -z Compress the executable using compress(1) and prepend a header line
- that calls zexec(1) to decompress and execute the binary. This will
- on average save 40% disk space at the expense of a slower startup
- time. Like -s the file must be actually copied for the flag to have
- effect.
- -N Use gzip -N to compress the binary. You may see up to 60% space
- savings, but it will take much longer. N is a digit from 1 to 9
- telling the compression effort, see gzip(1).
- -d Make a directory, usually to install files in a separate directory
- in a library. Intermediate directories in the path are created with
- the same attributes as the final directory. Only the attributes of
- the final directory are set if the directory exists.

- -o owner
- Set the owner of the target. This only works if the invoker is the
- super-user, or if install is run setuid root and the invoker is a
- member of group zero. If -o is omitted then the ownership is copied
- from the source file, or set to the id of the invoker if a directory
- is made.
- -g group
- Like -o, but for the group ownership of the target.
- -m mode
- Mode is an octal number that specifies the mode the target should
- get. The default is the source file's mode with a chmod a+rX
- applied to it, or 755 for a new directory. Implies -o 0, or -g 0 if
- a file is to be set-uid or set-gid and the invoker has permission to
- change ownership. This trick allows a group 0 member to install
- third party software, even though it expects to be installed by
- root.
- -S stack
- Sets the maximum amount of heap + stack that an executable may have
- when running. The argument is a C-style decimal, octal or
- hexadecimal number, optionally followed by the multipliers m, k, w,
- and b for mega (1024*1024), kilo (1024), "word" (2 or 4), and byte
- (1). Uppercase M is also accepted for those who know what S.I.
- means. The compilers use -S 32kw by default, that translates to
- 64kb for an 8086, and 128kb for other architectures. This option is
- ignored on a non-executable.
- SEE ALSO
- ln(1), cp(1), strip(1), compress(1), gzip(1), zexec(1), chown(8),
- chgrp(8), chmod(1), chmem(1), mkdir(1).
- BUGS
- Uppercase K, W, and B are also accepted for those who don't know what
- S.I. means.
