Redirection
Redirection
where command is the name of the command you want to look up. For
example,
help lc
summarizes the format and options of the lc command. If you just
say
help
you get a summary of help itself.
The information provided by help serves as a memory aid for people
who have already read the command’s reference page in the MKS
Toolkit Utilities Reference. help is not a replacement for the reference
pages.
Most of the commands we have discussed so far display information
on your screen. You can save this information in a file instead, by
typing
>filename
on the end of any command. For example,
cat file1 file2 file3 >xxx
writes the contents of the three files into another file called xxx. As a
result, all the information in the original three files is concatenated
into a single file.
Using >filename is called "redirecting output". The output from a
command is redirected from the screen to a file.
When you redirect output with >filename, the output writes over any
information that the file already contains. If you want to keep the
file's current contents, you can enter
>>filename
instead. This appends command output on the end of whatever the
file contains already. For example,
cat file1 file2 >>file3
appends the contents of file1 and file2 to the contents of file3. In
this way, file3 would consist of its original contents, followed by the
contents of file1, followed by the contents of file2.
