Bash script to compile and run a C program in one step

with 3 comments

Here is a simple script to compile and run a C program:

#!/bin/bash
# Script to compile and execute a c program in one step.

# Get file name without the .c extension
file_name=$(echo $1|sed 's/\(.*\)\.c/\1/')

# Compile the program with -o option to specify the name of the binary
gcc -o $file_name.out $1

# If there were no compilation errors, run the program
if [[ $? -eq 0 ]]; then
        ./$file_name.out
fi

The same could be done for C++ programs as well. Just replace the .c in the sed expression with .cpp and replace gcc with g++

  2. Could this be expanded? No demonstration of how it works, no explanation of a bunch of seemingly random characters. Very unhelpful to a beginner.
