Shell I/O and REDIRECTIONS
The standard input and standard output of a command may be redirected using
the special characters described below.
Use the file 'name' as the standard input:
command < name
Use the file 'name' as the standard output:
command > name
command >& name
If the file does not exist then it is created; if the file exists, it is
truncated, its previous contents being lost. You can use 'set noclobber' to
prevent yourself from doing this accidentally.
The form involving '&' routes the diagnostic (error) output, in
addition to the standard output, into the specified file.
Use the file 'name' as the standard output like `>', but append the output at
the end of the file.
command >> name
command >>& name
If you want to learn more about input and output redirection, you can read the
'csh' manual page by using the 'man' command:
man csh
