Programming in UNIX Environment : Using the shell

A greater than sign ‘>’ followed by a name makes a file of that name. the -n option of echo command is for omiting the newline. the ‘-l’ option for the ‘who’ command shows the details of users. The shell is a command like all unix commands. It is represented by ‘sh’.

$ > file //creates a file named file.
$ echo -n you are lucky
$ echo /* //prints the all the folders in root (not recursively)
$ echo \* //prints a ‘*’ character
$ who -l
