a description of the bug From: https://tiswww.cwru.edu/php/chet/readline/readline.html#index-rl_005fstartup_005fhook > Variable: rl_hook_func_t * rl_startup_hook > If non-zero, this is the address of a function to call just before readline prints the first prompt. rl_startup_hook is called before readline prints every prompt. a recipe for recreating the bug reliably --- rl.c ---- #include <stdlib.h> #include <stdio.h> #include <readline/readline.h> static int startup () { printf("startup\n"); return 0; } int main (int c, char **v) { char *temp; rl_startup_hook = startup; while ((temp = readline ("> ")) != 0) { printf ("%s\n", temp); } exit (0); } ---- $ ./rl startup > foo foo startup > bar bar startup ... a fix for the bug if you have one! add a flag variable to check the first call. -- Hiroo Hayashi
