If, for any reason, you want to use the IO redirection
indicators <,> or >> without having them function as such,
you can precede them with the ! sign.
For example, suppose you wanted to construct a command file to
explain how to use I/O redirection which contained the following
echo command:
echo To redirect $STDLIST use the construct, >filename.
|
This would cause filename to be a newly-created, temporary file
containing the string preceding it.
To prevent this from happening, insert ! before >filename, as
follows:
echo To redirect $STDLIST use the construct !>filename
|
The resulting display would be:
To redirect $STDLIST use the construct >filename
|
The ! can be used in the same way to escape the other redirection
indicators (< and >>) also.
