Use the > to redirect the output to a file. This will however override the existing content of the file. Use >> if you want to append the result.
You would use a pipe. For example. ls | grep cool The output of ls(the list of files in your current directory) is given to grep. Grep then finds and prints file names that include the word cool in them.
">" redirects all output to a file, overwriting any preexisting content.
If the perl script outputs to the standard output device, use the I/O redirection operators (>, >>, |) to redirect it somewhere else.
'grep' searches a file for lines which match a given regular expression.
DSGET
It depends on the shell interpreter you are using, but in general the I/O redirection operators are >, >>, |.
Redirect the output to a file on the other computer.
grep filename "http:" assuming that the URL's you want to find being in http.
grep clients Mercury
The C standard library provides stderr as the standard error file. It is an output file, much like stdout, except it cannot be redirected via the command line. By default, error messages via stderr are output to the console, the same as the undirected stdout. However, the programmer may choose to redirect stderr to a disk file or allow the user to choose a location via command line switches. Although error messages can also be output to stdout (or indeed to any output stream), it is best to keep error messages separate from the standard output stream. For instance, the user may choose to redirect standard output to a disk file or to the input stream of another program, while error messages are directed to the console.
To search a file for lines which match a given regular expression.
Redirect the output to a file via the command line. Print the file. For example, if the program is named foo.exe, the output can be redirected to a file named foo.txt with the following command: foo.exe > foo.txt Everything sent to std::cout by the program will now be sent to the file instead. Everything sent to std::cerr will be displayed on screen as normal.
