Question

I’m working on an assignment to write a program mirroring ac(1). The output of ac and my aac are both:

"       total        5.80\n"

I ran aac -file xyz > out1 and ac -file xyz > out2

However, when using diff out1 and out2 I get:

1c1
<        total        5.80
---
>       total        5.80

Getting the hex codes using od I get:

-bash-3.2$ od out1
0000000 020040 020040 020040 072040 072157 066141 020040 020040
0000020 020040 020040 027065 030070 000012
0000031
-bash-3.2$ od out2
0000000 072011 072157 066141 020040 020040 020040 020040 027065
0000020 030070 000012
0000023

I’m not sure where the difference is coming from.

See an ASCII table and note that 011 is tab, whereas you are using 040 spaces.
