Package: apcalc
Version: 2.12.1.13-3
Severity: normal
What works, and what fails:
# add 2 to index with 'for' loop (this works)
% for f in `seq 3` ; do calc $f + 2 ; done
3
4
5
# same code, but with a 'while read' loop (it fails)
% seq 3 | while read f ; do calc $f + 2 ; done
3
2
3
'calc' behaves correctly at first, (it prints 3), then outputs the
index '$f' without adding 2. Most utils aren't confused by 'while
read':
% seq 3 | while read f ; do expr $f + 2 ; done
3
4
5
I'd guess that a variable input with 'read' is subtly different,
(how?), and that 'calc' parses the command line in an unusual way. If
that's not a bug, then it should be documented in 'man calc'. (It makes
it hard to pump in a big list of numbers to 'calc'.)
Hope this helps...
