I have put together a list of useful commands for Unixes and Linux. These are Linux variants of the commands.
ls -alh list directory history lists a history of commands run cat Display file on screen grep keyword search less read a file and format for pages host displays server name clear clears the terminal screen exit exits terminal log in kill kills processes rm remove file cp copy a file mv move a file vi advanced text editor nano text editor strings Interprets Binary files and shows what can be printed on the screen cd change working directory pwd print working directory tail displays the last 10 lines of the file unless -n is used to tell it how many lines to go up -c is how many bytes you want. -f to follow the log. touch creates an empty text file and updates the modified date outputs the current date of the system which gives full binary path to commands
