Change the mode of each FILE to OCTAL-MODE.
ruby -run -e chmod -- [OPTION] OCTAL-MODE FILE -v verbose
# File un.rb, line 195
def chmod
setup do |argv, options|
mode = argv.shift.oct
FileUtils.chmod mode, argv, options
end
end
Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY
ruby -run -e cp -- [OPTION] SOURCE DEST -p preserve file attributes if possible -r copy recursively -v verbose
# File un.rb, line 68
def cp
setup("pr") do |argv, options|
cmd = "cp"
cmd += "_r" if options.delete :r
options[:preserve] = true if options.delete :p
dest = argv.pop
argv = argv[0] if argv.size == 1
FileUtils.send cmd, argv, dest, options
end
end
Display help message.
ruby -run -e help [COMMAND]
# File un.rb, line 222
def help
setup do |argv,|
all = argv.empty?
open(__FILE__) do |me|
while me.gets("##\n")

if all or argv.delete help[/-e \w+/].sub(/-e /, "")
print help.gsub(/^# ?/, "")
end
end
end
end
end
end
Copy SOURCE to DEST.
ruby -run -e install -- [OPTION] SOURCE DEST
-p apply access/modification times of SOURCE files to
corresponding destination files
-m set permission mode (as in chmod), instead of 0755
-v verbose
# File un.rb, line 177
def install
setup("pm:") do |argv, options|
options[:mode] = (mode = options.delete :m) ? mode.oct : 0755
options[:preserve] = true if options.delete :p
dest = argv.pop
argv = argv[0] if argv.size == 1
FileUtils.install argv, dest, options
end
end
Create a link to the specified TARGET with LINK_NAME.
ruby -run -e ln -- [OPTION] TARGET LINK_NAME -s make symbolic links instead of hard links -f remove existing destination files -v verbose
# File un.rb, line 89
def ln
setup("sf") do |argv, options|
cmd = "ln"

options[:force] = true if options.delete :f
dest = argv.pop
argv = argv[0] if argv.size == 1
FileUtils.send cmd, argv, dest, options
end
end
Create the DIR, if they do not already exist.
ruby -run -e mkdir -- [OPTION] DIR -p no error if existing, make parent directories as needed -v verbose
# File un.rb, line 144
def mkdir
setup("p") do |argv, options|
cmd = "mkdir"
cmd += "_p" if options.delete :p
FileUtils.send cmd, argv, options
end
end
Rename SOURCE to DEST, or move SOURCE(s) to DIRECTORY.
ruby -run -e mv -- [OPTION] SOURCE DEST -v verbose
# File un.rb, line 108
def mv
setup do |argv, options|
dest = argv.pop
argv = argv[0] if argv.size == 1
FileUtils.mv argv, dest, options
end
end
Remove the FILE
ruby -run -e rm -- [OPTION] FILE -f ignore nonexistent files -r remove the contents of directories recursively -v verbose
# File un.rb, line 126
def rm
setup("fr") do |argv, options|
cmd = "rm"
cmd += "_r" if options.delete :r
options[:force] = true if options.delete :f
FileUtils.send cmd, argv, options
end
end
Remove the DIR.
ruby -run -e rmdir -- [OPTION] DIR -v verbose
# File un.rb, line 160
def rmdir
setup do |argv, options|
FileUtils.rmdir argv, options
end
end
# File un.rb, line 32
def setup(options = "")
