Sorry Denys, but the current git is a regression.
For ex try:
$ echo "{print $2;}" > test.awk
$ echo "do re mi" > test.txt
$ busybox awk -f test.awk test.txt
^C
$ busybox awk -e '{print $2;}' test.txt
^C
$
It does not see the input file, so it hangs waiting for
an input.
Try my last patch, or based on the current git:
parse_program(llist_pop(&list_e));
}
#endif
- if (!(opt & (OPT_f | OPT_e))) {
+ if (opt & (OPT_f | OPT_e)) {
+ argc++;
+ } else { // no -f nor -e: take program from 1st parameter
if (!*argv)
bb_show_usage();
parse_program(*argv++);
- argc++;
}
if (opt & OPT_W) // -W
bb_error_msg("warning: option -W is ignored");
