I got a hack to the hack ... but that works :-)
It protects the slash, if it is in a range specification [/], so that
slash is ignored as a pattern/repl separator and the next slash is used.
static char *
parse_sub_pattern(char *arg, int inquotes)
{
char *idx, *repl = NULL;
unsigned char c, rg = 0;
idx = arg;
while (1) {
c = *arg;
if (!c)
break;
if (c == '[') rg++;
if (c == ']') rg--;
if (c == '/' && rg == 0) {
/* Only the first '/' seen is our separator */
if (!repl) {
repl = idx + 1;
c = '\0';
}
}
*idx++ = c;
if (!inquotes && c == '\\' && arg[1] == '\\')
arg++; /* skip both \\, not just first one */
arg++;
}
*idx = c; /* NUL */
return repl;
}
VAR="ab/cd"
echo ${VAR/[\/]/xxx}
--> abxxxcd
