command line - What Does Parameter Stand For? - Ask Ubuntu


i learn ubuntu commands , commands can take parameter. want ask 2 questions.

first (more general): parameters use same abbreviation (like "-n"), used same task?

second (more particular): if yes, stand -n parameter , task? if no, stand -n parameter , task gzip -n command?

each command has own parameters.

you can see running man command.

man gzip

 -n --name               when  compressing,   save original file name , time               stamp;  default.  when  decompressing,  restore                original  file  name  ,  time stamp if present. option               useful on systems have limit on file name length or when               time stamp has been lost after file transfer.
