Question
Write a script that runs a C file through the preprocessor and save the result into another file.The C file name will be saved in the variable $CFILEThe output should be saved in the file c
Solution
Here is a simple bash script that will run a C file through the preprocessor and save the result into another file:
#!/bin/bash
# Check if CFILE variable is set
if [ -z "$CFILE" ]
then
echo "CFILE variable is not set. Please set it to the path of the C file."
exit 1
fi
# Run the C file through the preprocessor
gcc -E $CFILE -o c
This script first checks if the CFILE variable is set. If it's not, it prints an error message and exits. If CFILE is set, it runs the C file through the preprocessor using the gcc -E command and saves the output into a file named c.
