How to redirect output of a command to a file of which name is defined in an environment variable?

You can redirect the output of a command to a file using the > operator in the command prompt or shell. To use an environment variable as the filename, you need to expand the variable using the appropriate syntax for your shell.

For Windows Command Prompt:

batchCopy code
@echo off

setlocal



:: Define the environment variable with the filename

set OUTPUT_FILE=output.txt



:: Run your command and redirect output to the file

your_command > %OUTPUT_FILE%



endlocal

For Unix-like shells (Bash):

bashCopy code
#!/bin/bash



# Define the environment variable with the filename

OUTPUT_FILE="output.txt"



# Run your command and redirect output to the file

your_command > "$OUTPUT_FILE"

Replace your_command with the actual command you want to run and redirect the output from.

In both cases, the output of the command will be redirected to the file specified by the OUTPUT_FILE environment variable. Make sure to replace "output.txt" with the actual filename you want to use.
