Linux commands are commands entered into a Linux terminal (command line interface) and it performs accordingly. For example: if you entered 'pwd' into the terminal prompt and pressed ENTER it would return the current working directory be it /home or /etc

'ls' will list all files and directories the specified directory. If no directory is given, the current one will be used as default.

the best way to learn Linux commands is to try them out for yourself which you can via installing Linux or downloading a live Linux CD, booting into it and type in different commands (as a normal, non-root user -- root has all kinds of super-duper powers and can break things easily).

AnswerIn fact, the 'commands' are programs. They can be stored in different directories, usually:




For example, when you type 'date' into a command line, the program /bin/date is launched. Programs in Linux don't usually have .exe in name. This program prints current date on users screen.




just type:

which command

at the prompt where command is what you are searching for and the Linux style computer will tell you.

i.e. :

%which CD


CD: /usr/bin/CD /usr/share/man/man1/CD.1.gz

so it says that the command CD is at /usr/bin and the manual is at /usr/share/man/man1.

There are many different commands available in Linux. Some of the most basic are:

  • ls - lists the contents of a directory
  • dir - same as above but with escaped spaces
  • mv - move a file
  • rm - delete a file (semi-permanent)
  • cat - reads a file
  • less - used to pipe lengthy output from a command so that it can be scrolled through. Use like ls | less.
  • cp - copy files. cp file1 file1copy
  • grep - search for text in a file. Can also be used to search for words in a command output. Example: ls | grep partoffilename
