In this simple C program, we demonstrate how to use Remove System call from C to delete the file created in current working directory. You can modify, extend the code as needed. $ vim remove_delete_file.c #include <stdio.h> int main(int argc, char **argv) { int r; const char *filename = "./testfile"; r = remove(filename); if (r == 0) printf("file : %s removed successfully\n", filename); else perror(filename); return 0; } $ gcc -o remove_delete_file remove_delete_file.c Create a test file, $ echo "This is testfile" > testfile Now, we try to delete this same file we created as above, $ ./remove_delete_file Once we executed the binary created by compiling C program, we can see that the test file we created gets deleted.

Command line execution

Terminalbash
gcc -o remove_delete_file remove_delete_file.c Create a test file, $ echo "This is testfile" > testfile Now, we try to delete this same file we created as above, $ ./remove_delete_file Once we executed the binary created by compiling C program, we can see that the test file we created gets deleted.

Gotchas and common issues

  • Permission checks - verify user access rights and sudo privileges before executing system-level operations.

  • Environment configuration - double-check path variables and dependency versions to prevent runtime failures.

  • Backup safeguards - maintain configuration backups before applying system or database modifications.

Following these steps ensures clean configuration and reliable execution for c program to delete a file – remove api.
