Ding! ... hurrying back to keyboard ... try this! (don't have the time
to test it all)
var="ab/cd"
echo ${var/\\//xxx}
--> abxxxcd
echo "${var/\//xxx}" (bash compatible!)
-->abxxxcd
allows to replace ? and *
var="ab*cd"
echo "${var/\*/xxx}"
-->abxxxcd
This fixes at least three problems I had in serveral startup scripts.
static char *
parse_sub_pattern(char *arg, int inquotes)
{
char *idx, *repl = NULL;
unsigned char c;
idx = arg;
while (1) {
if (!(c = *arg++))
break;
if (c == '\\') {
*idx++ = c;
if ((c = *arg++) == '\\' && !inquotes)
c = *arg++;
if (!c)
break;
} else if (c == '/') {
/* Only the first '/' seen is our separator */
if (!repl) {
repl = idx + 1;
c = '\0';
}
}
*idx++ = c;
}
*idx = c; /* NUL */
return repl;
}
