Issues using Gnu bc for scripts.

saslg · 01-20-2016, 02:00 PM

I've done stuff like this for a long time;

$ cat sum.bc
#!/usr/bin/bc
total=0
while (i = read()) {
total += i
}
print total, "\n"

$ cat numbers
33
78
21

$ cat numbers | sum.bc
132

But on some system this just hangs. It seem to be an issue more and more so I assumed somewhere along the way bc changed but I haven't tracked it down to a specific version.

Does anyone know what changed or when (version wise)?

All I've got is that if I add a "set -xv" to that before the read loop, it outputs 0. It hangs for me too.

Code:

bc 1.06.95
