Directing same output from a 'for' loop to two files?
To direct the same output from a for
loop to two different files, you can use the tee
command. However, the tee
command is not natively available in Windows. If you are using Windows, you can install Git Bash, which provides a compatible tee
command. Here's an example:
bashfor %%i in (1 2 3) do (
your_command_here | tee -a output1.txt >> output2.txt
)
In the above example, replace your_command_here
with the actual command you want to execute in the loop. The output of that command will be directed to both output1.txt
and output2.txt
simultaneously.
Here's a breakdown of the command:
tee -a output1.txt
: Thetee
command reads from standard input and writes to standard output and files. The-a
option appends the output to the specified file (output1.txt
in this case).>> output2.txt
: The>>
redirection operator appends the output of the command to the specified file (output2.txt
in this case).
Make sure to adjust the file names (output1.txt
and output2.txt
) to your desired file names or paths. The -a
option in tee
ensures that the output is appended to the file instead of overwriting it.
Note that the example uses double percent signs (%%i
) when using the for
loop in a batch file. If you are running the loop directly in the command prompt, you can use a single percent sign (%i
) instead.
