Redirecting output to a file
The output of a process can be redirected to a file by typing the command followed by the output redirection operator and file name.
For example, to redirect the results of the who command to a file named users, type the following:
who > usersNote: If
the users file already exists, it is deleted and replaced,
unless the noclobber option of the set built-in ksh (Korn
shell) or csh (C shell) command is specified.
To see the contents of the users file, type the following:
cat usersA list similar to the following is displayed:
