Redirecting command output to a file z/OS UNIX System Services User's Guide SA23-2279-00 |
|
Commands entered at the command line typically use the three standard files described previously, but you can redirect the output for a command to a file you name. If you redirect output to a file that does not already exist, the system creates the file automatically. Most z/OS® shell commands
display information on your workstation screen, standard output.
If you redirect the output, you can save the output from a command
in a file instead. The output is sent to the file rather than to the
screen. At the end of any command, enter:
For
example:
writes
the contents of the three files into another file called outfile.
All the information in the original three files is concatenated into
a single file, outfile.When you redirect output with >filename and
it is an existing file, the output writes over any information that
the file already contains. To append command output at the
end of the file, use:
instead.
For example:
redirects
the result of the sort to the file named output (instead of
standard output) and appends any error messages to the file outerr,
which is a record of errors encountered during various sorts.Suppose you entered:
In
this command, you see two redirections:
Here is another example with two redirections, sending both standard
error and standard output to a file. This command produces the program hello and
a listing with error messages in a file called hello.list:
